Our take on the JBL Synchros E50BT

It's happened to all of us. You're lost in your music when, suddenly, you're jolted as you feel your headphones pull at your head and your music suddenly stops. You've accidentally pulled the headphone cable out of your smartphone. There are two known cures for this problem: be more careful, or get a pair of wireless headphones like the JBL Synchros E50BT. These headphones have Bluetooth built in, so they can connect wirelessly to your smartphone or tablet. Lose the cable and use the earcup controls to play and pause music, adjust the volume, or even take a hands-free call with the built-in microphone.

The cure for a common problem

JBL Synchros E50BT wireless headphones

Connect the Synchros E50BT headphones to your smartphone wirelessly via Bluetooth and control music and calls with the earcup buttons (shown in Blue).

Lose the cable and use the earcup controls to play and pause music, adjust the volume, or even take a hands-free call with the built-in microphone.

Cleverly styled and well built, the Synchros E50BT headphones offer JBL's legendary sound, with large 50mm drivers producing plenty of clear detail and PureBass technology bringing the low frequencies to life. The over-the-ear design helps ensure outside noise stays out of your headphones, while keeping your music inside so it doesn't bother others at home or in the office. The earcups swivel and fold for easy storage when they're not in use.

Wireless or wired listening

The Synchros E50BT run on a built-in rechargeable battery, which provides up to 18 hours of use. If your battery runs down, you won't be stuck without music. Simply connect the included headphone cable and keep listening in wired mode. Then, use your computer or a USB AC charger to get your headphones charged up for more wireless use.

Share a song wirelessly

One pair of E50BT headphones is cool. Two pairs can do something really cool. You can stream music to another pair of headphones wirelessly using JBL's ShareMe™ technology. This allows two people to listen to the same song from the same source at the same time. You can share music with any two pairs of ShareMe compatible headphones.

Connects to blue-tooth very well. Sound fair but a little muddy. Overall an ok set of headphones when on sale. I would probably have been disappointed if I had paid full price

Pros: Easily connects to blue-tooth Fairly comfortable Great range

Cons: Mediocre sound Multi-function buttons are difficult.

Looking for something that my 20 & 23 year kids could use for working out. Read several reviews and even consulted a Crutch field rep. Made the purchase and so far extremely satisfied. They seem durable and have a very balanced sound. I only hope the new version is just as good.

At this price point you will not find better sounding bluetooth headphones. Not the most comfortable for my slightly larger head, and is more on the ear than over....Plastic head band makes me a little nervous, but holding up so far.

Pros: Sound

Cons: Comfort on larger head. Plastic build

Great sound!!!

Crutchfield Customer Review (What's this?)

WOW!!! Great Wireless-Headphones and the price wasn't bad either! They sound better far better thean my Bose headphones I purchase a couple of years from here. More volume, bass and clear too. I also like the built-in phone mic and the quailty at this point is great too. Now I'm wondering if the JBL Everest 700 have better sounding quality. Also, much PROPS to Crutchfield for having great products and they never sold me any Lemons...

Pros: It's all good!!!

Cons: Hmmmm, time will tell...

gregory from Pascoag, RI on 12/10/2016

Mid range and highs sound good. Bass is adequate. My biggest complaint is the unit's complete absence of outside noise-canceling.

Pros: Decent sound Good battery life

Cons: No noise canceling

best value in bluetooth headphones

jeffrey from ma on 10/18/2016

Crutchfield Customer Review (What's this?)

The JBL headphones are almost as good as some of the best wired headphones that you can buy. I recommend them highly because they sound terrific, with plently of volume and musicality, and a great price. I use them with my IPOD which doesn't have enough power to drive wired headphones effectively but connects to bluetooth just fine. A solid and modestly priced investment. A really good product from a company that I've been buying from for 40 years.

Pros: price, quality, sound, power, and battery life.

Cons: current limitations of bluetooth technology vs wired headphones

They broke

Scott from Elsberry, MO on 7/9/2016

The headphones had an over all great quality, but one day the right speaker stopped playing sound. It's disappointing that headphones that sounded so nice broke so easily.

Pros: They sounded great. They were comfortable. They had a long battery life.

Cons: The right side speaker went dead after only 2 weeks.

Great price and great sound. JBL makes great products and does not rely on marketing for all their success. Not as popular as other earphones but sound is much better



Works great. Volume is low

Mike from Louisville KY on 2/14/2016

Crutchfield Customer Review (What's this?)

The headsets work great. Bluetooth instantly to my iPhone without issue. Easy to configure. The sound quality is the typical high standard JBL is famous for. The phone functions are serviceable. There are a couple of negatives. The max volume is pretty low if you want to rock out. OK for most uses though. Also, the on the ear controls---there are 4 buttons--- are all flat with no noticeable to the touch quality so hitting the buttons without looking is a challenge. As for the categories of this review. Really! Coolness factor? What is that? If you are bigger or have bigger ears,the over the ear feature is really more like on the ear. That's why I give only 4 star for comfort. Sound quality takes a hit because of the lack of power. Looks to be built OK.

Pros: Sound quality ease of Bluetooth.

Cons: Buttons. Volume.

Who Knew

ken from NC on 1/1/2016

Crutchfield Customer Review (What's this?)

We purchased these as a Christmas present. Who knew the sound would be this good? THey are more powerful than the Beats bluetooth and half the cost with super clear mids, sharp High's, and realistic lows without distorting the true sound of the music.. Color choice was the cool bit and have a nice fit and finish to them. If your not sure who made them, well it is on all sides. "JBL" just to make sure everyone knows what your wearing! Control plate/disk is a nice idea but makes noise while listening to your tunes at higher levels. Bluetooth range exceeded my expectations along with battery life. Corded use also surprised with even more volume available. The headset feels like a solid performer and pairing with the phone was smooth. For the price they are a great deal

Pros: Sound is Fantastic! Blows the beats away with cleaner sound. Volume levels out perform those also. Choice of colors is a nice touch with easy music controls. When making & taking phone calls the E50BT handles them with excellent clarity, the built in mic is crystal clear without picking up back round noise to distract you. Then returns to your music where you left off. No wires, so the bluetooth freedom is what we were looking for. Simply put-again- BUY THEM!...

Cons: NO CASE........Who in their right or left mind has perfectly round ears? product description says 52mm "Around the Ears" we all found that the ear cups are a bit smaller when installed onto the "round cans" that changes the oval shape needed for extended comfortable around the ear use. Again NO protective travel/storage case! In my experience wearing for short periods were Fantastic with a large variety of music types. Control disk vibrates and has audible noise when used.

Far from great

Steve from Massachusetts on 11/21/2015

Crutchfield Customer Review (What's this?)

I usually like JBL products because it's always great value and reliable for the money. At this price point i wasn't expecting to be "blown away" but still I'm disappointed to say the least. First reason is comfort. After 1 hour of listening my ear lobes are so sore from being pressed up to the speakers because the padding is very hard and doesn't allow enough of a buffer between your ears and the speakers. It may not bother some but for those watching TV and wearing glasses buyer beware! Second reason, I find the on/off button very temperamental. you need to press it several times before pairing can take place. And third, the lack of depth and sound effects when watching TV is noticeable ( FYI I only use JBL Synchros E50BT for watching movies and TV).

Pros: nice look

Cons: Many unfortunately, starting with comfort. The padding is way too hard and doesn't allow enough room between earlobes and speakers. Noticeable lack of punch and depth when watching movies and TV.

Pretty good, but for the money probabally the best value so far.

mando from Colorado on 9/18/2015

Crutchfield Customer Review (What's this?)

The pricier Bluetooth headphones I have sampled are slightly better in some factors but if you take into account how much these costs, the JBLs would top the list every time. Regardless, these headphones are a solid performer, I use them for everything, I can see how the other pricier headphones I might baby thereby reducing enjoyment level, but I am not afraid to put these through the paces. That includes gym, yard work, and construction. They sound fantastic, the range is impressive, the bass is good but as others have stated not as pronounced as Beats, which I personally appreciate. Don't get me wrong most of my favorite types of music reside in the lingering, resonating lower frequencies such as Dancehall, Dub, reggae, hip-hop, dubstep and the like, however at this point I really enjoy taking in all that a piece has to offer and in the end the bass and lower frequencies are represented very well with these headphones. They are very rugged, having tossed them around a bit, getting them a little wet and stuffing them every which where they so far are holding up great. Battery life exceeds my expectation and so does the reception range. I put my phone in my cubby at the gym and just roam freely, I also leave my phone inside the house and work outside with no problems. If you are on the fence and price is a factor in your total assessment I promise you this BT headphone will not disappoint. I definitely am going to buy again.

Pros: Great sound, great range, very durable, reception range is fantastic and best of all the Price!! Also love the color choices(I got Blue)

Cons: I don't get the fold design(the way it folds), doesn't make sense for me, the button function is not my favorite(I like swiping), and although in the end the bass and lower frequencies are represented great sometimes I wish there were more bang.

Crutchfield Customer Review (What's this?)

Headphones are very comfortable, have great sound quality, display lots of detail and clarity for the jazz I listen to both voice and instrumental.

Pros: clarity, ear fit, detail of voice and instrumental. Sound does not beat you up can listen for hours without getting tired. Without noise reduction unit manages block the majority of the background noise without playing and undue loud sound level.

Cons: could use more bass and a carrying case. Have some issues with connecting via Bluetooth to my Ipod and android phone.

Great Headphones

Alala from Hawaii on 8/10/2015

Crutchfield Customer Review (What's this?)

Bought these instead of noise cancelling headphones due to the great price and the over the ear design. Definitely not noise cancelling but for the money, does the job of muffling exterior noise and music sound is great. The low volume setting could be slightly lower, minor issue for sure. People near me can hear my music when at 1/2 volume and higher. Would be nice if there was a case or bag included (especially with the white) to keep headphones clean and wires all together. I like the fact that two headsets can be linked.

Pros: Great sound, great price. Will buy another pair to pair!

Cons: At 1/2 volume and higher, people around me can hear my music. No case.

Pros: Look great, function great, well built and amazing Bluetooth quality!

good product for the price

MG from MN on 3/10/2015

Crutchfield Customer Review (What's this?)

Good product for the money that's a no brainer. They don't really have the uhhhhh I had hoped for that JBL has produced for me I ln the past but I guess I should have bought the more expensive ones I guess. We really bought a pair of them for the BT pairing option for traveling. Works just like the show on the crutchfield website. Great idea with that video by the way, keep it up!! Overall I am satisfied with my purchase. Would I buy them again if these get lost, YES.

Pros: Look nice Block sound when actively listening Easy using

Cons: Maybe it's just me I have large ears but these don't really do over my ears. They more sandwich them onto my head.


Pat from Memphis, TN on 2/17/2015

Crutchfield Customer Review (What's this?)

Very good headphones for the money. The build quality is good, the earcups a little uncomfortable at first till there are broke in, sound quality is very detailed, good bass that's not taking over the music, and best of all it's wireless!

Pros: Build quality, sound, and wireless.

Cons: A little uncomfortable at first till there are broke in.

Great sound and BT range

D from Fort Collins, CO on 1/22/2015

Crutchfield Customer Review (What's this?)

I bought these for my daughter initially for road trips. With pillows, blankets, stuffed animals, etc. the cord of my Bose was constantly getting tangled and yanked on. The bluetooth looked to be a great option and proved to be a great choice. Surprisingly, the sound quality of the JBL's are outstanding, the design fits my daughter perfectly (although the ear cups are a bit shallow for me), and the BT range is fantastic (greater than any other BT device I own). It is also nice to have the cord as a back up for when the battery dies. My only complaint would be it does not come with a case.

Pros: Great sound quality, Good fit, and excellent BT range

Cons: Does not come with a case. BT does not turn off with the synced device, you must manually turn them off or the battery dies quickly.

Nice bang for your buck I suppose

Rob from Portland, Or on 1/19/2015

Crutchfield Customer Review (What's this?)

I just really like the product. I needed something without wires for talking in the phone but still sounded good and other people could still hear me in my loud semi truck. The Syncros does just that.

Pros: Perfect for wireless calling

Cons: Listening to music is fine but I wish it had more base and i wish it didn't have a limiter on how high the volume can go. That being said it is still loud enough and JBL is saving my hearing.

Great value.

Joseph from California on 1/9/2015

jb from Ohio on 1/1/2015

Crutchfield Customer Review (What's this?)

Wow! I love a quality sound, especially a good bass and this has it!! I got it for my grandson thinking he might not be happy because it isn't Beats, but he is really happy with them!!! I don't need wireless because I have great ear buds but I'm considering getting another pair for myself because the sound is better than my buds. They say wireless isn't as good but I'm telling you, this is great!!

Pros: Comfortable, great bass, clean clear tone quality, easy to use, biggest bang for the buck!!

Cons: Doesn't shut out noise completely but very good

Greg from Burke, VA on 9/7/2014

Crutchfield Customer Review (What's this?)

I am very impressed withe these headphones. I have used Beats Solo and Monster, these are far superior to both. The sound quality is excellent and for non noise canceling headphones they sure do cancel out just about everything. I bought these to use while mowing my fields and was quite surprised when I could barely hear my thirty hp diesel tractor. The volume level is very good and the fit on my big head and ears was surprisingly comfortable even after 8 hours of mowing. The Bluetooth works easily and has a very good range. Now we just need to see how they will hold up long term.

Pros: Very comfortable Very good at canceling noise even though they are not noise canceling headphones

Cons: Have not found one yet!

Overview: The JBL Synchros E50BT Bluetooth headphones offer convenience and performance in one stylish and comfortable package. With ShareMe technology, you can even share your experience with another set of headphones. The E50BTs have a built-in Lithium-ion rechargeable battery that provides all day music playback capability. When the battery becomes exhausted, you can plug in the supplied auxiliary cable and continue listening.

Drivers: The Synchros E50BT over-the-ear headphones feature large 50mm advanced drivers with PureBass performance in a lightweight closed design. The 32-ohm drivers give you crystal-clear stereo for enjoying your music or carrying on a phone conversation.

ShareMe can be enabled using two E50BT headphones, a E50BT and an E40BT, or two E40BT headphones.

Good reviews [ Glen  Dec 03, 2017 ]
I was an audio engineer in a former life and bought these for my son's birthday. For the sale price, I've not heard anything even close. They quickly fully charged & easily synced. I listened while cooking Thanksgiving dinner & cleaning up the house. After 3.5 hours, I had to get them back in the box before my son came ;-). VERY good sound, extended BT range, and were reasonably comfortable > 3.5 hours (slight earlobe fatigue). Liked the sound and value so much I just ordered myself a pair! [ MICHAEL  Nov 26, 2017 ]
Extensively researched blue tooth headphones and discovered these. Considerably less expensive than any other site. Excellent product at an excellent price! And, it ships free! [ Donald  Nov 25, 2017 ]
I like the JBL brand, and these headphones offer good features at a reasonable price. I primarily plan to use these with my Pixel 2 phone, but may pair them with other devices as well. [ Samir  Nov 24, 2017 ]
I like JBL products and these had good reviews. [ G  Nov 24, 2017 ]
Ive been a JBL listener since 1984 when I got my first set of speakers in the Navy, 350A towers. I still have those and they still sound great. I also have a JBL surround system. I have read reviews about the E50BTs and I have great confidence that I will love them as well! [ F  Nov 22, 2017 ]

Great sound. [ Spiro  Nov 13, 2016 ]
EXCELLENT highend, bass, and build quality! I compared this JBL E50BT over the ear design with two $299 models and I could not hear the difference! The tactile controls are easy to navigate to and the battery easily lasts 4-5 days at low listening levels. The sound quality during phone calls is clear and crisp even though these are not "noise canceling". The only con is these are large and I recommend trying them on at Target or Kohl's. [ Roger  Feb 05, 2016 ]
Great sound, wireless, and price compared with other brands. [ FRANCISCO  Jan 05, 2016 ]
For the price the sound quality is great and the battery lasts a very long time. [ Ramsey  Dec 14, 2015 ]
The JBL E50BT head set I purchase on Dec 2014 Is the best purchase i made. I purchase many Bose, Dr dre, Koss ,Sony & plantronic, but the JBL e50bt nice bass is my favorite I pay 130 on sale not bad for blue tooth over the ear. Plus free shipping Thanks Crutchfield! C F music lover [ cesar  Dec 11, 2015 ]
I like that they don't look as Bulky as the Skullkandy blue tooth earphones I bought (that i will be returning). Also, i watched several review videos on you tube and they say the sound is very good. [ Michael  Dec 07, 2015 ]
Decent reviews, cost and they are Bluetooth. [ John  Dec 06, 2015 ]

I like the color, despite my wife saying I look like a 5 year old. Also, she got the black ones and I don't want to mix mine up with hers. [ Michael  Dec 07, 2015 ]

7 questions already asked

Sorry, no. The PS4 does not offer the ability to pair with standard Bluetooth headphones as is (only "Official" and "Licensed" headsets). There may be third party accessories that enable this option but we do not carry any here at Crutchfield. [ Ryan  Nov 11, 2017 ]  Staff
Theyre Bluetooth so they should pair with anything. Unless they've changed the design, I'd recommend a different manufacturer. The model I owned used the sound port as a charging port as well, rather than USB. I lost one of the channels and returned them. Check out Bose. [ GEORGE  Sep 26, 2017 ]
Yes, If your TV is Bluetooth Capable. [ Armando  Feb 07, 2016 ]
I have been able to if you have blue tooth enabled speakers/amplifier that drive the sound coming from you tv. [ Sean  Feb 05, 2016 ]
i honestly don't know. Does the TV have Bluetooth. Call JBL would be a better was to go on this. [ Bruce from Boonton  Feb 05, 2016 ]

No [ Armando  Feb 07, 2016 ]
Yes you can the only thing is when one device emits a transmission to the device it will stop the other device transmitting, but it is still connected. Also it doesn't connect both at the same time u have to manual connect one. Example I connected my phone and tablet at the same time and ran music thru the phone and just played with the tablet. I had the sounds up on all and every time i touched something on the tablet it cut the music off so i had to keep restarting it. I muted everything on the tablet and it was fine, the music never stopped. Now the reverse will work too. Run music thru the tablet and phone idle. When you get a phone call it stops the music off the tablet and phone takes over. For me this just not practical, the music cuts off when I'm getting a phone call anyway if I'm just using my phone as the player. Hope that helps. [ Dwayne  Nov 03, 2014 ]
We are giving as a gift specifically for use with an iPhone 6. There is no reason it should not work but we have not yet tested. [ JESSE  Dec 17, 2014 ]
Yes, it will work great. [ Mudi  Dec 17, 2014 ]
I can not say for sure, They work great with the I 5s and latest generation I touch. Also, I have had no problem with any of our laptops, tablets or car radios. [ GREGORY S  Dec 17, 2014 ]
These will work with any Bluetooth. I have these connected with my I touch and android. [ ALEJANDRO  Dec 17, 2014 ]
I dont see why not, the work with my iphone 5, should work with anything BT. Plus they come with a cord! [ Diane  Dec 17, 2014 ]
Sorry I don't have the 6 yet... However I do like the headphones! [ MATTHEW  Dec 17, 2014 ]
As long as you have Bluetooth capabilities you should have no problem. I use mine on my Samsung S5 and my Samsung Tab S tablet. So with the iPhone 6 I would suspect you would have no problems. Hope this helps. [ Troy  Dec 17, 2014 ]
The over-ear design does block a reasonable amount of external sound from coming in,but these are not noise-canceling headphones. So far I am pleased. [ Bryce  Jan 13, 2015 ]
No, Im pretty sure they don't because they didn't advertise that they did. But if you want quality sound, I really love the bass on these better than Bose or Beats. I was amazed. [ Joy  Jan 09, 2015 ]
Not noise canceling. They are very quiet and gave awesome sound. Much better that Bose, Sony, Dre beats. I've had them all. Noise canceling headphones make me feel like I have a pressure on my ears. Hope this helps. [ TERRY  Jan 09, 2015 ]
they are not noise cancelling. [ Russell  Jan 09, 2015 ]
No just passive via the over the ear design. Works well. The sound is exceptional. A bit uncomfortable for extended wear in my opinion, but a quality pair of wireless headphones. [ JASON J  Jan 09, 2015 ]
