Rated 5 out of 5 by from Introduced new undertones After listening to a track that I have heard many times I realized I had actually been missing some of the soft spoken lyrics and undertones. The range is expansive and pure. Even when playing at a modestly loud volume the music was pleasing to the ear, not sharp or harsh. Well done.

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 also found out that you cannot plug the USB into a USB charger then plug it into the wall because the voltage and/or amperage is too high. You may have to plug the USB into a computer/laptop.

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

Is there a sound app for the iphone to support the E40BT

Asked by: Stabbers
A sound app is not needed. The E40BT is 100% compatible with an iphone. Just turn on the EB40T and the bluetooth function on your iphone. The E40BT will appear in the bluetoot setup of your iphone and connect automatically as bluetooth speaker within a few seconds. That's all. Very easy.
