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.

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 ⭐️

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.

How long do the headphone have to charge before they turn on? Also quick guide has bad instructions. nothing is marked as to what the buttons are!!! Very difficult to set up these headphones.May return them.

Asked by: who cares
We are sorry to hear that the Quick Start Guide does not work for your needs. The E40BT charges for 3 hours from 0-100% using the cable provided with the unit. We will be more than glad to assist you with any queries regarding the E40BT and its functions, simply submit a case at jbl.com/contactus and our Customer Service Team will be glad to provide assistance.

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.

Hi.. my boyfriend is planning to buy 2 E40BT for the both of us. Can we able to used it while watching movies on my tablet at the same time? Thanks

Asked by: Luna77
Certainly. One of the E40BT&rsquo;s features is the ShareMe function. This enables sharing your audio with another set of wireless headphone that features ShareMe. To use the ShareMe function on your E40BT &ndash; 1: Pair and connect the headphone to a source device via Bluetooth 2: Pause music or disengage voice calls from the source device. 3: Press ShareMe&trade; button once on the first headphone then LED starts blinking rapidly. This headphone is ready to connect to the second headphone. 4: Press ShareMe&trade; button twice on the second headphone then LED starts blinking slowly. LED stops blinking after ShareMe&trade; connects. Play the music on the source device. Two headphones are ready to share the music. Press ShareMe&trade; button once to disconnect.
