Our take on the JBL Synchros Reflect BT

by David Brown

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).

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.

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.

Overview: The JBL Synchros Reflect BT in-ear sport headphones are designed for active lifestyles. The ergonomic ear buds stay in your ear as you go through your workout. They are equipped with a highly-reflective cable to give you added visibility at night.

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.

Freebit Ear Tips: The JBL Synchros Reflect BT in-ear sport headphones include three pairs of Freebit ergonomic ear tips, making sure there's a size to fit most everyone. These ear tips are angled to match your ear canal, and have flanges that help keep them in your ears, even during the most rigorous activities.

Rechargeable Battery: These in-ear headphones are powered by a rechargeable battery located in the right ear bud. The battery can be charged in approximately 2 hours via the supplied Micro USB cable. A fully charged battery provides about 5 hours of battery life.

Retractable Cord: The headphones are connected together via a 2' sweat-proof retractable flat cable. You can adjust the length of the cable for the best fit, using the attached cord clips.

Magnetic Cable Management: Each ear bud has a magnet along the bottom that enables you to keep them securely clasped together around your neck when they're not in use.

JBL Synchros

Written By Dennis, Dallas, TX on Wednesday, September 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.
No cables to tangle and/or pull out of your device. Bluetooth, good price.
Cable connect right and left headphone could be more flexible.

Good sound, stay in place decently

Written By Mike, Evanston, IL on Monday, August 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.
Sound, Bluetooth, Price
Fit could be more secure, Inline controls don't change track

Not so cool looking

Written By hChristopher, Birmingham, Al on Tuesday, August 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.
Good, snug fit in ear; Appears to be of good quality
Button controls adjusts volume only and does not advance track like the competition offers
