Rated 5 out of 5 by from Great I bought this two weeks ago and have only used it about 6-8 hrs. I still haven't had to charge it up yet. The booklet that came with it is hard to understand but it wasn't hard to figure out how to use it. I think it will be a good headset. I like the idea that I don't have to have any cables to use it.

Rated 5 out of 5 by from JBL E40BT Headphones I have had my E40's for about 3 months now. They are awesome headphones. When I first used them I was shocked at how good the sound stage was.. excellent rendition. I replaced my Audio Technica ATH-3 with these EB40Tafter 40 years.. There's a reputation on it's own.. Older guys will know what I am on about (ATH-3)..

Rated 5 out of 5 by from These Headphones Sound Awesome I own a lot of JBL products Home audio speakers like the JBL L112, L96, L15. All three sets driven off of a vintage Pioneer SX 1980. My truck even has two pair of JBL T545's in it. I also own several sets of headphones J55A in black and J55I in white. I have now added a set of SYNCHROS E40BT to my collection. I have heard other brands and nothing comes close to the sound quality of JBL.

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.

I recently broke my wired earphones I use for my desktop computer. I am tired of wired earphones. My computer does have blue tooth ability, will these work on a desktop computer? 

Asked by: Mikey1972
As long as your desktop computer has bluetooth capabilities, the E40BT should work wirelessly without any issues.

i went to use my head set the jbl e40 bt and only the left side works. they were both working the other day ad i've never dropped them or got them wet

Asked by: mikey2016
Usually when something this suddenly happens, it is very often a change in the setup. Please check the settings in your source device (smart phone, computer, etc.) to be sure that the balance (left to right) is set in the middle/center. Also, if you are connecting through a wire, not Bluetooth, be sure the plug is thoroughly connected, all the way in. If it is slightly out, you will lose the right channel. If none of this fixes your problem, I notice that you are are in Canada. Please contact our Canadian headquarters, Erikson at info@eriksonconsumer.com or call 514-457-2555 ext2503 and they will gladly assist you.
