Our take on the JBL Synchros E50BT

by David Brown
JBL

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).

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.

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 around-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.

  • 50mm dynamic drivers
  • around-the-ear, closed-back design helps block out external noise
  • Bluetooth 3.0 and A2DP connectivity for wireless music listening and phone calls with compatible smartphones
  • earcup buttons offer music, volume, and call controls for compatible Bluetooth connected smartphones
  • built-in earcup microphone with echo-cancellation for clear, hands-free calls with a smartphone
  • PureBass technology delivers low-frequency response with detail and accuracy

  • built-in rechargeable battery offers up to 18 hours of music listening
  • USB charging cable included

Features

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.

Bluetooth: The Synchros E50BT supports Bluetooth 3.0, with A2DP v1.3, AVRCP v1.5, HFP v1.6, and HSP v1.2. The left ear cup is equipped with a microphone featuring Konnexx echo-cancellation technology to give you a clean connection and clear, hands-free calling. The headphones are compatible with iPad (mini, 3rd and 4th gen), 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.

ShareMe: JBL's exclusive ShareMe technology lets you wirelessly and simultaneously share your music with another ShareMe-enabled headphone. When you are paired with a Bluetooth source device, you can then add a second pair of headphones and listen to the same source at the same time--a concert for two. ShareMe can be enabled using two E50BT headphones, a E50BT and an E40BT, or two E40BT headphones.

On-board Controls: The headphones' left ear cup includes a 4-way Multi-function Button (MFB) that lets you control your music playback and phone calls:

  • Press MFB up/down: Raises volume up or down
  • Press MFB forward:
    • Music: 1x play/pause; 2x next track; 3x previous track
    • Phone Calls: short press answer call; long press reject call; manage 2 calls at same time
  • Press and hold MFB forward: 1x fast forward; 2x fast reverse
  • Press MFB backward: ShareMe function

Battery: The built-in 3.7V Lithium-ion rechargeable battery (730 mAh) provides approximately 18 hours of music playback time, or 24 hours of phone talk time. The battery charges in approximately 3 hours via the included USB cable.

JBL E50BT

Written By Greg, Burke, VA on Sunday, September 07, 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!
