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 bought my headphones from amazon and had it shipped here to the Philippines. Our electricity voltage here is 220 volts. CAn I Do Wall charging?

Asked by: Mdlc
The E40BT comes with a multi-voltage power supply. It will work from 100-240 volts so it is completely safe to plug it in to the wall to charge.

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?

I'm looking at the spec sheet for your Synchros E40BT headphones and I see that the spec sheet states that the frequency response is either 10hz-24khz or 20hz-22khz. Can you tell me which is correct?

Asked by: VML1
The correct frequency response of the E40BT is 20Hz – 22kHz as shown in the updated Spec Sheet.

Hi, I yesterday received my E40BT but cannot connect to my Macbook Air, do not see the device in the bluetooth options. Any idea how to solve the problem?

Asked by: AlexRB
If you have the latest Bluetooth hardware of your MacBook Air, you can start the pairing process by enabling both Bluetooth on. To pair the E40BT with your Macbook, press and hold the POWER button for 0.5 seconds. The LED light indicator should blink fast if it’s blinking slowly, you need to press and hold the POWER button again until it starts blinking fast. Scan for BT devices on your MacBook and you will find the E40BT and connect. If you're unable to pair the E40BT, it is possible that your MacBook 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.

My Head phones will not hold a charge they are less than a year old and I can't find the box.. They were christmas gift. Why Wouldn't they hold a charge this soon 

Asked by: Az52
In order to ensure that the issue is caused by a defect in the E40BT, try using a different USB charging cable at an alternate power source. If the issue persists, it may have developed a fault. In this case, please submit a request at http://www.jbl.com/contactus and the Customer Service team will be more than happy to further assist you.

Hi, is there any specific kind of USB wall adapter that can be used to charge this headphone? or any adapter should be fine? I ask that because some of them have an output of 5V-1A and other 5.3V and 2.1A (ipad).

Asked by: Diogo
You can use any USB adapters, just make sure that the output range is at 5-6V @ 1.0-1.5A anything exceeding that output would be harmful for the headphones.

Hello, Is there an special app for the zenfone 2 to the play/pause/etc functions start working?

Asked by: sammaugust
The E40BT headphones don't actually need any special app to work, as shown in the quick start guide, you can use the Multi-Function Button(MFB) to Pause/Play, skip tracks forward or backward and fast forward or rewind audio from your device. Those functions also depend on the media player that you are using from your phone.
