Our take on the JBL Synchros Reflect BT

Lots of things can slow you down when you're working out, but your music shouldn't be one of them. Cut the cord connecting your headphones to your smartphone with the JBL Synchros Reflect BT. These wireless headphones use Bluetooth to sync with your phone, so you can run, walk, climb, or bike unimpeded by dangling cables. Heart-pounding JBL sound will keep you moving, with clear detail and punchy bass. The sweat-proof earpieces aren't afraid of a little moisture, giving you no excuses to give up on that last lap or final few reps.

Music and fitness shouldn't be at odds

JBL Synchros Reflect BT wireless sports headphones

The Sychros Reflect BT headphones use special ear tips designed to keep them in place during movement (shown in Green).

The sweat-proof earpieces aren't afraid of a little moisture, giving you no excuses to give up on that last lap or final few reps.

Wireless music and calls

A wireless Bluetooth connection lets you stream music and audio from your smartphone to the Synchros Reflect BT headphones from as far as 40 feet away. That's helpful if you'd rather set your phone down instead of having it strapped to your arm. The built-in rechargeable battery offers up to five hours of playback and can be refueled via the included micro USB cable. A three-button remote on the reflective cable that connects the earpieces is designed for an iPhone® or iPod®, so you can adjust the volume, skip songs, and play and pause music. There's also a tiny built-in microphone so you can take hands-free calls.

Clever design

A couple of cool design features set these headphones apart from other Bluetooth models. The earpieces are magnetic. When you're taking a water break and want to remove the headphones, just clasp the earpieces together and hang them around your neck so you don't have to set them down and risk losing them. You can also adjust the length of the cord that connects the earpieces using the retractable tether.

Product Highlights:

  • 8.5mm dynamic driver in each earpiece
  • Bluetooth 4.0 and A2DP connectivity for wireless music listening and phone calls with compatible smartphones
  • sweat-proof
  • magnetic earpieces let you connect them to wear around neck when not in use
  • three-button remote for controlling music playback and volume with an iPhone, iPad, and iPod
  • built-in microphone for making calls with an iPhone
  • wireless range: up to 40 feet
  • built-in rechargeable battery offers 5 hours of listening (USB charging cable included)
  • earpieces are connected by a bright, reflective cord with a retractable tether for custom length
  • includes 3 pairs of silicone ear tips to ensure a comfortable fit and proper noise isolation
  • frequency response: 10-22,000 Hz
  • warranty: 1 year
  • Our 60-day money-back guarantee

Excellent product. Very usefull in my training.

JBL Synchros Reflect BT

Greg from Houston, TX on 12/13/2016

Crutchfield Customer Review (What's this?)

They worked well for about 6 months and then started to cut out. Maybe due to sweating on them. I stopped using them because they would cut in and out so much.

Pros: Priced well Great fit

Cons: They did not last very long

Don't fit all ear types

Adam from Houston,TX on 5/15/2016

These might be great for some people, can't keep them in my ears. Crutchfield was great about exchanging them!

Pros: Sound great.

Cons: Ear attachments don't work for me

Crutchfield Customer Review (What's this?)

Decent Bluetooth to work out with. Needs to be a little bit louder and better bass

Pros: sleek and light

Cons: Falls out easily, and not enough bass for JBL


david from denver, CO on 2/13/2016

Crutchfield Customer Review (What's this?)

I bought these because of the JBL brand. Had I not torn up the box, I would have returned it. Good sound, but not a good design for going in the ear or staying in. Falls out easily. Bluetooth pairing was very easy. Difficult to adjust volume without pulling out of your ear.



Just OK

Anonymous from Hendersonville, NC on 2/7/2016

Crutchfield Customer Review (What's this?)

Looked to be a good product for hands-free use. Took forever to link to phone. Only directions was a Quick Start Guide with mostly pictures. Hard to find plug-in port to charge. (It's behind right plug.) When it is charged, it is in the on position. You have to turn it off, then on again. It flashes blue when on, but no indicator when it is off. Apparently, you cannot turn it off after is is synced. Will go off by itself after a period (??) of time. Ear buds can be tiring after long usage. Sound quality is good. Considering return.

Pros: Good sound quality. Compact design.

Cons: No extensive instructions for use. Charging port hard to find initially. Does not seem to allow turning off manually.

Brothabush from New York on 12/28/2015

Crutchfield Customer Review (What's this?)

I love the JBL brand and it doesn't matter what it is from speakers to amplifiers, however the JBL refelects are poorly made and the sound quality is not all that. Maybe it is because you get what you pay for, the price was reasonable and I wanted wireless during my workouts. The earbuds fell out of my ears during my workout and I was not happy with that to try and keep adjusting.

Pros: Price was Reasonable

Cons: Poor quality, JBL puts out better product then these ear pphones.

John from Missouri on 12/27/2015

Crutchfield Customer Review (What's this?)

Nice build and comfortable. Sound is pretty good for buds. Blue tooth is excellent. I've read the poor reviews with respect to connectivity and almost thought twice on purchasing. But happy I did. I can leave my phone in one area of the house and be 20-30 feet away and have good sound with no cutting out.

Pros: Sound quality Connectivity

Cons: Price but you get what you pay for

Great Companion

LECZ3 from Puerto Rico on 12/27/2015

Crutchfield Customer Review (What's this?)

Very good product for outdoors to keep you with away from wires and your smartphone away from environment conditions.

Pros: Good sound and noise reduction

Cons: Lost of signal if smartphone is in the back pocket. On and off button need to be pressed several times to operate.

Do not stay put

B from Missouri on 12/21/2015

Will not stay in my ears at the gym. I bought hem for exercises like squats, because I always crush regular cords after about a month. These will last a long time, but do not stay in my ears. I'm always reinserting them.

Pros: Sounds good when fully inserted. Don't move. Sit still, and they are great.

Cons: No bass because they always get loose. Horrible for working out. Wish I would have tried another style of Bluetooth headphones. Don't get these if you are active.

After further review

Seagull from Alabama on 12/9/2015

Crutchfield Customer Review (What's this?)

Originally I was going to give these headphones a 4 star rating based on their design alone. I don't find them as obtrusive as some other reviews did but that's a matter of personal preference. The sound quality is pretty good. They aren't as good as Bose Quiet Comfort headphones but what can you expect. I bought them to use while running. After I started to use them I noticed quite a bit of dropout and breakup in the sound as I ran. I had m iPod in an armband about 8 inches from the headset and the connection was horrible. Normally when I run I listen to podcasts so I could put up with it for a bit but after a while it became unbearable. There is. O way you could listen t music with this kind of choppy sound. At that point I would have dropped the rating to one star and I was ready to go back to the old hardwired earbuds. Today when I was running it got so bad that I took off my armband to turn it off completely. When I got the iPod into my hand at normal arms length, the dropouts ceased completely. I continued on with my run and my iPod in my hand and experienced no more breakups or choppiness. It's a bit of a pain to run with it in my hand but it's not really that big a deal so I've raised my rating to 3 stars. The sound is good. They are very small and lightweight and the charge lasts through my entire run. If you run with your iPod or phone in your pocket or around your waist this might work for you but otherwise forget it.

Pros: Small size. Decent sound. Good battery life (for me anyway)

Cons: Dropouts and sound breakup when worn with an armband.


AdamD from Kansas on 11/27/2015

Crutchfield Customer Review (What's this?)

Pretty good sound for their size. Battery life is 3-5 hours depending on volume level. Their size makes them very convenient.

Pros: Wireless and good sound.

Cons: No cons for their size.

Good fo the price

Sonicfidelity from Virginia on 11/22/2015

Crutchfield Customer Review (What's this?)

These are pretty good for the price. The sound does change while working out. This is due to the design of the earbud not the Bluetooth (which works quite wee and consistently). Getting them to stay in my ears is difficult at times; it has taken some getting used to. Overall they are a good value compared to other more expensive wireless workout headphones.

Pros: Bluetooth

Cons: Design Sound

First Wireless Headphones

Scott from Illinois on 11/2/2015

Crutchfield Customer Review (What's this?)

I purchased these after my second pair of Klipsch rugged 4i headphones broke. I have had these for a week so far and only used them at the gym every day for an hour to hour and a half work out. This fit takes some getting use to, however they block out more sound than my old Klipsch and seemed louder. They ever felt like they were going to fall out do to sweat, I was drenched pretty much every work out. I have small ears so finding a good fit is a pain. I was definitely surprised how loud they are and they do charge rather quickly. Two issues prevented me from giving them 5stars, I thought the battery should last a little longer and the lack of a function to skip tracks directly from the headset itself.

Pros: Price, a great price to go wireless at a cost 130 cheaper than Beats. Loud, good secure sound isolating fit with a little trial and error.

Cons: Cant fast forward tracks from the headphones controls. Wish the battery last a little longer. The stated 5 hour time is on the money.


Dotyn from Los angeles on 10/20/2015

Crutchfield Customer Review (What's this?)

I Was disappointed at first as not have a charger but after that I figured it out I love the headsets great sound not enough bass, adjusted the iPhone that help would highly recommend this to anyone looking for wireless headsets to exercise by.

Pros: Comfortable

Cons: No charger

Richie from Massachusetts on 9/15/2015

Crutchfield Customer Review (What's this?)

A bit confusing to use for the first time, but once I figured it out it's OK. Would be better if the battery life was longer as I have a 12 hour flight to the Orient on my horizon.

Pros: I works: Beats didn't X3.

Cons: Short battery life

Crutchfield Customer Review (What's this?)

Would not recommend. Had to return after less than one month because they will not hold a charge. I have an exact same pair of these corded which I had to go back to using.

Pros: Sound is okay

Cons: Will not hold a charge

JBL Synchros Reflect BT

Mark T from California on 8/31/2015

Crutchfield Customer Review (What's this?)

So far, I like them, but the sound quality could be better. I've tried adjusting the equalizer in my iPhone to almost all the available settings, and while the sound quality does change, it's still not quite as good as I'd hoped.

Pros: Comfort, Bluetooth, microphone for talking on my phone.

Cons: Sound quality.

Lightning strike twice?

Ben from Delaware on 8/15/2015

Crutchfield Customer Review (What's this?)

Ordered, was excited about going wireless. Headphones were larger than expected (stuck out further from the ear than it appeared in the photos) but style won't keep me from using. Like any device made to be used in a unique surface, the fit wasn't that great but normal for every other headphone I've ever used. The soft rubber tip that "hooks" into your ear is unique and while not entirely comfortable during the first few lengthy sessions is no worse than an over-the-ear hook. Overall sound quality, for a small device, not bad. *Big issue* *Two returns for this* *Does lightning strike twice?* After the 3rd / 4th use, headphone either quit powering on completely, required 10+sec on the "on" button to turn-on if at all, and would not powered-on- first time it turned off about 15min into use, then would turn-off after 60 seconds or so. First time I figured it was a fluke. Second time, same issue? No thanks. Return for refund and will shop elsewhere.

Pros: wireless

Cons: bulky, two products returned for same issue- failure to power-on/stay-powered on.

Great Technology

MarkA from Nevada on 7/26/2015

Crutchfield Customer Review (What's this?)

Excellent product, connected fast, worked smoothly, great sound Highly recommend

Pros: Paired easily to phone and tablet, worked smoothly, great sound quality, comfortable fit

Cons: no issues found

Me like my new JBL Synchros

GP Green from Alaska on 7/14/2015

Crutchfield Customer Review (What's this?)

These headphones are my first wireless bluetooth headphones. I reviewed other headphones & it came down to two makes. I asked Crutchfield customer support which of the two they thought were best. They said of the two this one was the best sounding period. They do sound good. Easy to operate. Talked on the phone in a loud truck & the people on the other end had no problems hearing me speak normally. I run & they're perfect for that too. I'd buy again.

Pros: sound quality & ease of use.

Cons: big earbuds.

Happy Father's Day!

Kayln from Oklahoma on 6/23/2015

Crutchfield Customer Review (What's this?)

Mu daughter was looking for a father's day gift for her dad who seems to have everything when you try to think of something to get him. She came to my office and saw a colleague with the headphones and knew that was the gift!! My co-worker was very pleased and highly recommended the product. So we ordered and we couldn't agree more! It was the perfect gift...he absolutely loves it.



Not bad for blue tooth

SeanS from Virginia on 6/11/2015

Crutchfield Customer Review (What's this?)

These are def above average but not perfect headphones. I was in search of ones I could use while exercising. Pros are comfort on your ears, and after a brief connection period where the sound drops in and out, they seem to lock on and your music is mostly fluid and doesn't skip. Cons are they do take a little while to get there. The buttons are a little small and hard to get your hands on, and the other con is that delay while you wait for the skipping to stop. When it does you're golden. I've noticed this doesn't happen as much if you're not moving and walking, but I want them for exercise so...? Also the buds are a little bit bigger then ,most in ear (I guess to house the BT technology? All said I would still recommend these to others.



Noise reduction

Koot from Idaho on 5/24/2015

Crutchfield Customer Review (What's this?)

All in all a nice product. Mostly use while gardening and mowing the lawn. Less decibels are required to filter out outside noise when compared to using other quality earbuds during similar activities.

Pros: Frankenstein ears while wearing them. So cool

Cons: A bit bulky

JBL Earbuds

Barbara D from Wisconsin on 4/20/2015

Crutchfield Customer Review (What's this?)

They are hard to keep in my ears. I am not sure I have figured out the best way to set them in my ears. The main problem is that the sound breaks up even though my iPhone is in my pocket. The range is not very good. However, the sound quality when it is not breaking up is good.

Pros: Good sound quality

Cons: Small range and hard to keep in ears when exercising.

Crutchfield Customer Review (What's this?)

I have been fighting to keep these in my ears I use them for work and they continually come out. Sound is real good but I bought them specifically to stay in while I work and so far a big fat zero.

Pros: Lack of cable to ipoh is nice.

Cons: Won't stay in ears.

Crutchfield Customer Review (What's this?)

I bought these bluetooth wireless headphones for working out. I was tired of the cable from my wired ones getting caught on machines and slapping against me while I run.

Pros: No cable connecting headphones to your phone. Easy to use.

Cons: If phone is more than 5-6ft away the music with start to break up. Not a big deal for me cause my phone is either in my pocket or in my gym bag next to whatever machine im using at the time.

Great product

MarkR from Culpeper, Virginia on 2/12/2015

I love this wireless/Bluetooth headphone. It is much lighter and less cumbersome than one I had purchased a few years ago. It is light and the sound quality is great. The fit in the ear is good and keeps it secure. Great product!

Pros: lightness, ease of use, quality of sound


JBL Synchros Reflect BT

reg from California on 1/22/2015

I saw these and decided to try them because I use them in a gym setting and like not having to hassle with wires.

Pros: look great, like the idea of reflecting light for safety, sounds good and connects quickly with my device.

Cons: did not matter what size ear buds, they slipped out of my ears. It was kind of annoying to be working out and needing to readjust the buds on a regular basis.

JBL Synchros Reflect BT Review

AndyM from Arlington, VA on 1/16/2015

Crutchfield Customer Review (What's this?)

I love the ergonomics and the sound of these headphones (when they work correctly). However, the Bluetooth connectivity is horrendous (using with iPhone5S). I use these when I workout (strength training) and get terrible connectivity with my iPhone in my pocket. Music skips in and out even after unpairing/pairing, restarting phone etc. If all you do is cardio on treadmill/elliptical/bike and you keep your phone stationary these work great. Anything other than that, prepare to be very disappointed. I expected more from the JBL reputation. Perhaps, I got a defective unit.

Pros: Ergonomics & Sound

Cons: Bluetooth (music skips in and out constantly while working out)

Nailed it!

Jay Likes his music from New Mexico on 1/15/2015

Crutchfield Customer Review (What's this?)

Amazing design. So. Earphones. Don't expect to the world to come alive in new colors! Go get some nice open ears, dedicated tube amp, and QUALITY signal. I stress Signal. These ear phones kick. First and fore most. If they don't fit right, they will nvr sound right. In a mobile headphone you cant be fussin' with em' all the time either, defeats the purpose. The design on these are perfect! Oval shaped because your ear canals not round. Derp. They don't intrude into your ear canal! This is big! The design seals that "gap" with a large flange that doubles as noise reduction, and fit. Finished of by the crazy ear spike. Works Great. I paint, Workout, drive around, no cables, no excessive cable brush noise! Gold. So Audio Quality, I run a new Denon to NHT's at home. yadda. The key is quality signal. Spotify, sounds really good. mixes at a higher bit and depth rate sound better. I run FLACC files through the house player on a samsung galaxy 3? The house player utilizes the BT 4.0 energy benefit and the new algorithmic codec, can't remember name. Point being... Get good Signal. They Sound Awesome! And the fit seals the deal. Great Buy!

Pros: All good!

Cons: They will die in a year, Li ion. oh well.

Doesn't hook up

Steven from the Washington, DC Area on 1/2/2015

Crutchfield Customer Review (What's this?)

I purchased these as a gift for my wife. After charging them they won't hook-up to my wife's Android phone or my IPhone 6. We consider ourselves to be tech savvy, however, these operate on an older system and don't seem to be compatible w/our phones. BTW, Crutchfield's tech dept. is so overloaded (post holiday) that one can't get through.

Pros: Shipping was prompt.

Cons: Don't work.

Pros: Light weight, multiple size ear cups, easy to use while jogging or as a passenger in a car. good design

Cons: non so far

All about the earpiece

Anonymous from Jacksonville, FL on 12/30/2014

Received as a Christmas gift, and I started with the small earpiece thinking it would fit better and it did! However the sound was bad almost tinny. When I switched to the large earpiece it made a complete 180 difference. I am a taller guy and the large fit even better than I imagined. I did some hardcore gardening and hole digging and these stayed in place the whole time. The bass is no joke, perfect for earbuds. It's not DAC quality but it's better than I expected. Only annoyance is having to move the cord to front of neck to have better call quality for voice. It works behind he head but you will sound like you are a mile away when you are talking to someone.

Pros: Super comfortable. Virtually nonexistent. Awesome Bluetooth headset, the best and most comfortable.

Cons: Cord placement for calls.

whitneylee.p from Lincoln, NE on 12/22/2014

Crutchfield Customer Review (What's this?)

These headphones are great. They are especially useful when running or at the gym. Not having a cord in the way when you run is ideal and the quality is spot on. The adjustable ear bud sizes are a life saver.

Pros: Small, Great quality, Bluetooth ready, multiple uses

Cons: expensive

JBL Synchros

GWags from Buffalo, New York on 12/20/2014

Crutchfield Customer Review (What's this?)

Work in lab where freedom of movement is essential. These provide all I need as far as sound quality and ease of use. Over ear models provide better sound quality and noise reduction. but for my use these are a very good product

Pros: Sound quality


JBL Synchros Reflect BT

TDM from Houston, TX on 12/19/2014

Classy look however, tough to get a good fit as well as very uncomfortable after ~30 minutes. BT feature sucks - cuts in and out with every step. Have to hold phone close to headset then works great. After a week of use gave them to my son went back to my old BOSE.

Pros: Coll color

Cons: Horrible BT feature Uncomfortable after ~30 minutes

Not so good for the price

Arod from Puerto Rico on 12/18/2014

They look great, the fit is ok once you find the right ear piece, but the sound quality and the Bluetooth range is not good. Original iphone headphones have a much better sound and deep bass than the JBL. I had my phone on my back pocket and the connection started to get disrupted. I place the phone on my bed and walk 15 feet from it and had interruption on the connection. I tried this since they are intended to be used mostly on bike riding and I just realize they won'e be as good as what paid for them. Will return to look for the Jaybird.

Pros: Look and weight. Easy to pair.

Cons: Sound quality, Bluetooth range, control are small and not so easy to identify by the touch.

Jorge J. from California on 12/16/2014

Crutchfield Customer Review (What's this?)

These JBL work great, easy set up and removes the hassle having long cords hanging around. As far as comfort, after 30 minutes or so, you feel some discomfort and have to readjust. Great sound and also work very well when on phone mode.

Pros: Easy to set up and use.

Cons: Some discomfort after extensive use and have to readjust and only 5 hours of continuous playtime.

Not what I was hoping for. They don't stay in while working out and the ear buds stick out quite a bit from your ears. The picture is misleading, I thought they were banded to keep spring tension on your ears so they would stay in better...but not



JBL Synchros Reflect BT

Justin S. from Fort Collins, CO on 12/12/2014

Crutchfield Customer Review (What's this?)

So far it's a test and trial period to get the right fit in my ears. There has also been a learning curve on how to get used to using them. With all that said, I love the freedom from being tethered to my iPhone! I hated when working out and the old head phone cord would get caught or snugged the ear piece out of my ear! It's really quiet amazing to see something so small and compact that has blue tooth and phone control capabilities. The volume doesn't go as loud as a normal pair of ear phones, but that might not be such a bad thing, maybe save my ears a little! Over all I am really liking these and would suggest them to anybody who works out, rides bikes, runs, anything!

Pros: No cords, doesn't drain your phone as fast, phone controls, and simple to use!

Cons: Volume isn't extremely loud, and getting a good fit has been difficult

Cool bluetooth earbuds!

Saw them on sale and I was looking for Bluetooth headphones. Excited to get them but after 3 rounds with them I knew it was not ment to be.

Pros: Comes in a cool green color.

Cons: Falls out of ear consistently regardless of size adaptor. Sound quality lacks bass otherwise alright. Connector band never feels right on the back of neck.

Sound Quality Very Poor

ITC3 from California on 11/13/2014

Crutchfield Customer Review (What's this?)

The look cool while wearing. Very convenient when walking or working out. However, the sound quality is dramatically different from my BOSE SoundTrue's. The difference was dramatic enough for me to return the JBLs & keep using my wired BOSE SoundTrue's. Everything else was ok but sound quality is a deal breaker for me......JBLs just aren't comparable to BOSE.

JBL Synchros

Crutchfield Customer Review (What's this?)

I absolutely enjoy having the JBL Synchros added to my iTouch. it allows me to workout without having the cord catch on anything when lifting weights, running, or cycling. My friends are jealous and that battery lasts a decent time even with long rides. I don't ever want to go back to normal ear buds.

Pros: Setup, use, and quality are representative of JBL brand name. Sound quality meets/exceeds my needs to enable me to workout and enjoy music. The fit is adjustable and I have experienced no problems. bottom line: I would purchase again, I will purchase for my wife and would recommend them to anyone. If the next version is waterproof it may support triathletes.

Cons: Sometimes it can lose the Bluetooth link with my iTouch but it rapidly re-establishes link. I keep my iTounch on my arm and that helps.

Closest out there, but still not quite perfect yet.

Crutchfield Customer Review (What's this?)

I'm actually really impressed with the durability of these and even more impressed with the sound quality. They sound great for how light they are. I use these strictly for my training, which is pretty intense. So far they've stayed in 100% and haven't had any issues with the comfortability during training sessions. I believe these are the best workout headphone out there (bluetooth, or even wired for that matter) but I'll list 2 areas where I think they dropped the ball on these. First issue is the bluetooth connection, it's surprising, good and bad. I thought it would be stronger while my iPod was on my body, doesn't matter if I'm holding it or wearing it on my hip, my music seems to cut out regularly. On the flip side, my solution in the gym is to clip my iPod to my water bottle and can walk around up to ~75ft away with no connection issues at all. 2nd issue I have with these is the tension clips, these are such a bad design. I can appreciate an adjustable fit, it was a major selling point for me, however for active headphones there needs to be a way to lock these clips in place. I like a fit closer to my head but I find these clips move out all workout and I have to adjust them at least 10x workout. It's so annoying I'll either return these until JBL fixes it or put some janky electrical tape on them. These just aren't in that perfect realm just yet, but at this price, these are the best out compared to everything else.

JBL Synchros Reflect BT

CWEEKS from Hirqm, Ga on 10/13/2014

Crutchfield Customer Review (What's this?)

Used while riding a road bicycle. Connecting strap was not a problem, once you spread the two black clips apart, which eliminates the "bowtie" and locks in the adjusted strap length. On a ~40 mile ride they stayed in place, no problem with wind noise, no interruptions in sound, and no snags from strap on clothing or helmet straps. They were comfortable and sound quality was excellent. Also used on a 3.1 mile run. They stayed in place the entire run, no snagging of strap on clothes. Although, with iphone in my pocket while running, the audio would interrupt briefly, but with phone in hand or in an arm band I had no interruptions. The magnets on the back of the plugs held in place flawlessly around my neck while walking/driving. Great buy!



JBL Synchros

Dennis from Dallas, TX on 9/17/2014

Crutchfield Customer Review (What's this?)

Overall I'm very satisfied with the JBL wireless headphones. They are great during exercise or using during travel. I've synched them to my iPhone, GPS, iPad and iPod with no issues. When using conventional headphones I would constantly be pulling the headphones from the device during any physical activity which is no longer the case with the JBLs. Very satisfied with this purchase.

Pros: No cables to tangle and/or pull out of your device. Bluetooth, good price.

Cons: Cable connect right and left headphone could be more flexible.

Good sound, stay in place decently

Mike from Evanston, IL on 8/25/2014

Crutchfield Customer Review (What's this?)

I looked long and hard for a set of headphones to replace my broken Motorola S9-HDs. I finally found them with these JBL Reflect's. The sound quality won't blow you away but it won't leave you disappointed either. I'm not an audiophile but I know what good sound is. I like the design of these, though I find the strap adjustment is mostly useless. I have to expand it all the way or when I turn my head the cord sticks to my neck and pulls a plug out of one ear. My only problem so far is that these do tend to slip out even when I'm just sitting at my desk (which is where I mostly use these). It's not that big of an issue. Considering all the other options on the market right now I think these are hands-down the best given the price and functionality. I really wanted headphones I could use at work without disturbing my co-workers. All the over-ear ones I tried leaked sound so bad my co-workers could hear every word (yes, I listen to music a little loud for most people). These don't leak at all and, as I said, they sound pretty darn good. I can't even crank these all the way up because it would be too loud.

Pros: Sound, Bluetooth, Price

Cons: Fit could be more secure, Inline controls don't change track

Not so cool looking

hChristopher from Birmingham, Al on 8/19/2014

Good concept but lacking basic track control features. The wire band is very rigid contributing to awkward fit around neck. Magnetic feature to hold ends together around neck while not in use are ineffective as magnets are too weak to keep held together.

Pros: Good, snug fit in ear; Appears to be of good quality

Cons: Button controls adjusts volume only and does not advance track like the competition offers


Brenda from Arcata CA on 8/10/2014

These are great good sound not too expensive nothing better than not being connected to your ipod/ipad by a tether.

Pros: looks good sounds good

Drivers: The headphones are equipped with premium 8.5mm drivers for solid bass response and clear highs.

Bluetooth: The Synchros Reflect BT features Bluetooth 4.0 technology for a wireless connection. You can keep your smartphone or Bluetooth music player in your pocket or gym bag while you workout. The Bluetooth connection has a range of up to 40 feet.

Note: The headphones do not include a wired connection.

Compatibility: The in-line 3-button remote and microphone is compatible with a wide range of smartphones and mobile devices. The outer buttons turn the volume up or down as needed, while the center button turns on the power, pause/play your music, or answer/end your phone calls. The remote/mic works with iPad (mini, 3rd and 4th generation), iPhone (5s, 5c, 5, and 4s), iPod touch, MacBook Air, MacBook Pro, Mac mini, Android 1.5 (Cupcake) to Android 4.4 (KitKat), and Blackberry 1.0 to Blackberry 10 OS.

Go into your settings for the Bluetooth. I answer phone calls all the time on my headphones, just click the reflect option wen answering a phone call. Really an easy flawless system. [ Mark  Feb 23, 2016 ]
Hi Mark. I'm not sure if they'll work with the S5. I use mine with a Motorola Moto X and a Samsung Rugby and they work fine with both. Hope this helps. [ Norma  Dec 31, 2015 ]
Don't know all I have are apple products but I imagine so [ christopher  Dec 29, 2015 ]

Yes you do just like answering call with headphones [ christopher  Apr 21, 2015 ]
Yes press the middle of the black bar until you hear the chime . [ Patrick  Apr 21, 2015 ]
Yes. The power button is located on the controls pad up near one of the ear buds. The volume controls are there, as well. To skip to the next track, just double "click" the power button. When the headphones are powered on, they immediately connect to your blue tooth device (at least to my iPhone). You only have to sync to them on the first use/connection. [ Brian  Apr 21, 2015 ]
It's simple: on the right earbud you lift up the cover (the JBL logo) and it will expose the micro USB port, then plug in the cable and the other end into a USB power source and it will start charging. It's easy to overlook the cover because they designed it to look cool, but if you look really carefully you'll see a small tab you can stick your fingernail in to lift it up. [ Richard  Jan 24, 2015 ]
end of the right ear piece flips open [ Don  Jan 24, 2015 ]
On the ear bud opposite the control bar, if you look closely you'll notice a little cutout on the JBL plate. That JBL plate covers where you connect the charger. Get your fingernail under the cover and lift up. Viola! Hope this helps! [ Matthew  Jan 24, 2015 ]
Hi, Lana, You can either plug the USB end into a computer or plug it into the wall using an adapter. I find that plugging into the wall with the adapter charges it much faster. Now, if you're asking where to plug into the headphones themselves, there is little, round, plastic cover on either the left or right ear piece. The removable cover has a notch in it so you can get under it to release it. Just pull the little cover away from the ear piece, and plug the cable into the ear piece. The removable cover is where the JBL logo is printed, if I'm not mistaken. Hope this helps! - Brian D. [ Brian  Jan 24, 2015 ]
The right ear bud has a charging port. Your finger nail works great to lift the jbl tab. [ Juan  Jan 24, 2015 ]
The end of the lighted earpiece that appears solid is actually removable. Look very closely and you will see a "pry slot" that you can work with a fingernail or small, thin tool. [ MICHAEL W  Jan 24, 2015 ]
On the back of one of the earphones where it reads jbl is a clip you have to pull up with you finger nail. Use the provided charger or any android phone charger [ nathan  Jan 24, 2015 ]
The back of one of the ear pieces opens to USB mini [ christopher  Jan 24, 2015 ]
The cable has to make ends. The larger one is for a computer USB port. The other plugs into the earphones port, usually under a plus on the outside of the right earpiece. When you make the connections a red light goes on that is on the right earphone showing it is charging. When the re light turns blue, it is all charged and ready to use. [ David C.  Jan 24, 2015 ]
safest charge is to plug into computer. charging into another type of usb charger such as apple iphone charger will burn your headphones out making them useless. [ Roger  Jan 24, 2015 ]
In the ear plug there is a folding cover that says JBL with a small lach on the bottom pull it up and you will see the port . [ Patrick  Jan 24, 2015 ]
Hi Lana. To charge, just pull the small cover that says JBL from the right earpiece and you'll find a spot to plug in your cable. Hope this helps. Larry. [ Norma  Jan 24, 2015 ]

Not good for noise cancelation, you need to use the right size fittings which come in three sizes. Also depends on your device as well and the volume setting. Both my Samsung tab 4 and iPhone 4 put out just about the same sound range. You may need the ear muff ear phones, the noise cancelation pricy ones to mow the lawn. More so, after about 30 minutes or so you start feeling some discomfort and need to readjust. Otherwise beats having that long wire hanging around, sounds very clear when talking in phone mode. [ Jorge J.  Dec 16, 2014 ]
I think so. I'm a mechanic and they drown out the surrounding noise. I Couldn't be happier with mine. [ marvin  Dec 15, 2014 ]
Yes they sounded great. The only problem I had was in my diesel truck the person on the other end could not hear me when I was on the phone. [ DANNY  Dec 15, 2014 ]
No. Not quite. I disagree with some of the reviews that don't like the sound - it is very good as long as you get a good fit. Still not as loud as wired though. [ JOHN  Dec 15, 2014 ]
Sorry but they are a gift for our son & he hasn't opened them yet. [ LISA  Dec 15, 2014 ]
I use them in the gym with 75% of volium capacity I'm very happy [ YAIR  Dec 15, 2014 ]
Yes you can [ christopher  Dec 08, 2014 ]
I make them with my I phone so I would say yes you can and they work great [ L  Dec 08, 2014 ]

Yes. Just know that the reliability of these lasting long is poor. I had to send them back to JBL for a replacement after 6 months, they just died. Also the buttons to work them are very small and hard to work if you have large hands/fingers. Sound quality is great but they do have issues. [ KEVIN  Jan 12, 2016 ]
Yes you can. Don't really like the ear bud type headphones though as they are always falling out. They also briefly lose connection is phone iline of site is blocked. [ BOB  Jan 12, 2016 ]
A couple of hours, but don't buy these if you plan to use them during activity. I jogged with mine; first pair lasted 8 months, and the replacement pair 6 weeks. [ charles  Sep 17, 2015 ]
My recommendation would be not to purchase these head phones. They have many gliches for something so simple and don't hold a charge for an extended period of time. [ Paul  Sep 16, 2015 ]
Wife's earphones. She says and hour, two tops [ Bruce from Boonton  Sep 16, 2015 ]
