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.

I am trying to watch a movie with my Bluetooth Capable PS3 and E40BT Headphones. When I try to pair them it asks me for a Passcode but I have no Idea what that would be because I never made one.

Asked by: SecretMan4444
The passcode you must enter is "0000" and you will be good to go.

where can I purchase a replacement charger for this product

Asked by: Deshops99
Any USB to 2.5mm Aux cable can be used to charge the headphones. The cable is commonly available at electronics shops. If your unit is under the 1 year warranty, you can submit a case to www.jbl.com/contactus and file a warranty claim for the charging cable of your headphones.

Just purchased a pair of Synchros E40BT's; AWESOME sound! I use Google Voice to make phone calls from my computer. How do I activate the microphone? (Google voice has a set-up window that permits device selection--done... still no mic.)

Asked by: J3ff
Unfortunately, the microphone feature will only work when the E40BT is connected to most mobile or smart devices.

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 need to replace the USB recharger jack. Aux jacks that fit my laptop headphones from other brands do not fit the JBL E40BT. What name should I be looking for? 

Asked by: jac tarl
The Synchros E40BT headphones require a USB charging cable with a 2.5mm plug. We recommend contacting your local JBL Customer Support for information regarding parts replacements.
