Rated 5 out of 5 by from Great headphones... I ordered these with a notice that they were back ordered. Low and behold, they showed up earlier than scheduled. Thanks Harmon. I tried a different sites E40BT's, and one side died 2 days later. So I found these on Harmon site. Ecstatically happy.

hi, i have jbl E40BT and one side has stop working?

Asked by: eyalm
I read a lot of people with the same problem. First off let me say that I love the sound and comfort of these headphone. However mine did the same thing, I exchanged them under warranty at Canadian Tire, but after a few months the second pair did the same thing, worked great at first then one side stopped working. I am the type of guy that likes to take stuff apart to learn how and why things work, So I opened the headphones and found a wire that was not soldered or got pulled off it's soldered spot from moving/adjusting the headphones around. I re-soldered the wire and reassembled the headphones using hot glue to hold the wires in place so they can no longer get tension when adjusting the headband, They HAVE been working perfectly for over a year now. " DO NOT " open them if they are under warranty, I hope this helps any other handymen out there, and maybe JBL should look into their assembly line.

How do I charge the headphones? I put it on the charger for a few hours but doesn't seem to want to charge if anyone can please help me I'd appreciate it 

Asked by: ODiaz
I figured out that the 2.5 mm jack has to be fully pushed in hard into the left ear cup. It's a small flaw that had me confused for an hour. I also though my headphones were defective.

Bluetooth connected, no sound transmitted. Win 10 pro. CSR Bluetooth Radio USB dongle. Anyone know why, have a fix?

Asked by: lordbear73
The E40BT COACH Limited Edition utilizes the standard Bluetooth Stereo Audio drivers available in most laptops. There are two different Bluetooth protocols, one for Headset Audio used for talking on the telephone, and the other for high quality stereo audio listening. Being that the E40BT COACH Limited Edition is a speaker; your computer must connect to the E40BT COACH Limited Edition using the Stereo Audio protocol. Your best bet is to go into your control panel and find the Bluetooth setup. This setup usually provides a setup wizard and will take you through the steps to install the drivers needed for Stereo Audio.

I have a pair of JBL Synchros E40 BT and ive enjoyed using them for about a year but now theres no sound i the left ear piece. What do i do now?

Asked by: SageGT
I don't think this is a "set-up" problem because I had the same problem.  It began intermittently and soon failed.  After carefully removing the left ear-fusion, support, and speaker itself I discovered that one wire to the speaker had become disconnected from the printed circuit board.  The two wires to the speaker are attached near to corner of a circuitboard and was soldered back on.  Use care if you try this as the parts that hold the speaker piece on is very fragile and connected in what appears to be in a backward fashion.  This also requires experienced soldering techniques.  Be careful.

I was able to use my E40BT headphones and the pairing process worked fine, but they became unpaired. Now I am unable to pair them again. I have rebooted my nano, and sometimes E40BT appears as a device but it will not finish pairing. Tips for pairing?

Asked by: PhilB
Hey Phil, I had the same issue with my iPhone. To resolve this I went to Bluetooth settings, removed or "forgot" the E40BT headphones from the "My Devices" list, turn off bluetooth, turn bluetooth back on, and re-paired (make sure bluetooth button is flashing on headphones while trying to pair). The E40BT headphones should appear under the "Other Devices" list below the "My Devices" list in the Bluetooth settings of your phone. Select the device you're trying to pair. Hopefully this helps!

where can I purchase a replacement charger for this product

Asked by: Deshops99
Ok so if the charger was available at most electronics stores you would be correct however it is not !!!! I'm at a technology store that is second to none when it comes to electronic devices having the latest and greatest technological devices they could be found and they do not sell  however you can get them on Amazon for about nine dollars
