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 got my jbl e40 about a year and a half ago. The left ear lost the sound after it got hit but luckily, we got it fixed by a jbl repair in Manila. Now the foam insulation of the same ear is falling off due to the stitching coming apart. Can this be fixed?

Can more than one set of headphones be set up to the same device? And if so how?

Asked by: baaramewe
Yes, you can use ShareMe feature to connect with another set of ShareMe enabled JBL wireless headphone. This is how it works. 1. Pair and connect the headphone to a source device. 2. Pause music or disengage voice calls from the source device. 3. Press ShareMe button once on the first headphone then LED start blinking rapidly. This headphone is ready to connect to the second headphone. 4. Press ShareMe button twice on the second headphone then LED starts blinking slowly. LED stops blinking after ShareMe connects. Play the music on the source device. Two headphones are ready to share the music. Press ShareMe button once to disconnect.

I have the JBL E40BT bluetooth headphones.How do I charge and how do I know my headphones are charging.

Asked by: Cutno
The E40BT can be plugged in to USB ports on your laptop/computer for charging. It can also be charged directly on a wall outlet using a power adapter. The LED lights up red when charging, and changes color to white when charging is complete.

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

I can not get my E40BT to pair with each other. I followed the manual 

Asked by: Jerryaub
It is imperative to know that once the ShareMe button is pressed, LED should start blinking rapidly. If it doesn't flash quickly, pairing cannot take place. Try again with a short, firm press less then a second. If this doesn't help, please submit a case at www.jbl.com/contactus and the Customer Service team will be more than happy to assist you.

My computer detects or "authenticates" the JBL E40BT headset but will not connect. How do I get it to connect

Asked by: geowulf
It is possible that your computer does not support or is not setup to support Stereo Audio Bluetooth connection. 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.

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.

The E40BT headphones are not sweat-resistant. Over exposure to sweat or water can compromise the controls and sound.
