On-ear stereo headphones featuring Bluetooth® connectivity with ShareMe music sharing.

The new E40BT takes JBL’s legendary signature sound, adds advanced Bluetooth and mobile features, and packages it all in a sleek design that’s both comfortable and head-turning. JBL’s engineers have combined generous 40mm drivers with PureBass performance, treating your ears to expansive frequency response (10hz to 24KHz) with full, undistorted bass. Bluetooth technology allows wireless connectivity with phones, tablets and music players, while giving you single-button access to crystal clear, connection to your mobile phones, using echo-cancelation technology. Built-in ShareMe™ technology lets you to stream music wirelessly to another ShareMe-equipped headphone. A built-in rechargeable Li-ion battery gives 16 hours play time, and when the battery is flat, use the included aux cable for continued, uninterrupted listening. Beyond great sound, the E40BT is designed for comfort, style, and durability. The Ergonomic headband and 360-degree swivel hinges allow for a personalized fit and long-lasting comfort. The butter-soft, leatherette ear cups cradle your ears for all-day comfort and work to seal out distracting ambient sound. The E40BT’s sleek design and five unique color combinations make a visual statement that’s as striking as its sound.

Rated 5 out of 5 by from Battery life and sound I got these for Christmas, I took them out of the box and used them almost non-stop for about a month before they died, plus, the sound quality was absolutely fantastic, I would like a little bit more bass though, and the little screws on the front fell off, other than that 6/5 ⭐️

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
We are sorry to hear that you are having issues pairing your E40BT with your iOS devices. To place the E40BT in pairing mode, while the headphones are on, press and hold the Bluetooth button. The LED should start flashing, indicating that the E40BT is now ready to pair. Check back on your iPhone or nano and you should now be able to connect to the headphones.

Hello, connected in bluetooth to my iPad, in audio-conferences, I can hear very well but my relatives almost don't. It's the same on the iPhone (telephone conversation). any way to increase the mic volume ?

Asked by: lucP
There is no way to increase the volume of the microphone on the E40BT. One thing we should check is on either device, see if the E40BT is selected as a media playback device or as a headphone. If the earlier was selected, select the headphone profile. This should fix your issue.

What is the pairing code for my E40BT? I would like to pair my device with my home telephone. thanks!

Asked by: Paragon
The E40BT doesn&rsquo;t have a pairing code. Simply connect it via Bluetooth will do. Unless your home phone has a Bluetooth transmitter, like most smart devices, the connection cannot be done.

I have a MOPW bluetooth music receiver that plugs into my computer in the headphone jack, that I have been trying to pair with, and have had no luck, have you any suggestion for me, any reason it shouldn't pair.

Asked by: RBCoburn
If what you have is a Bluetooth Receiver, this will not work. What you would need to stream audio to the E40BT is a Bluetooth Transmitter instead. A Bluetooth Receiver&rsquo;s purpose is to allow your PC to receive files via Bluetooth and not transmit them to a headphone/speaker.

Can I pair my synchros e40bt with my laptop? It can't seem to find the drivers when I try.

Asked by: chadspry
It is possible that your computer simply does not have the necessary/updated drivers to stream audio via Bluetooth. The EVEREST ELITE 700 does not require any specific drivers. It utilizes the standard Bluetooth Stereo Audio drivers available in most computers. There are two different Bluetooth protocols, one for Headset Audio used for talking on the telephone, and the other for high quality stereo audio listening. Being that the EVEREST ELITE 700 is a headphone; your computer must connect to the EVEREST ELITE 700 using the headphones protocol. 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 Bluetooth headphones audio.
