JBL® Everest™ Elite 300

The Elite headphones are equipped with an auto off capability to preserve battery life when not in use. The headphones will automatically turn off after 10 minutes of inactivity: meaning no audio or voice. In situations where the user would like to enjoy the benefits of the ANC technology only - when not listening to music or talking on the phone , we advise to turn off the Auto Off feature in the app to keep the headphone running continuously.

The EVEREST models 100, 300 and 700 are all updated with the HID (Human Interface Device) tool, available in the download section for each model. This tool works with Windows computers only. The EVEREST ELITE models are updated with a USB tool available on the special Everest web page. This tool is available in both an Apple MAC OS version and a Windows version. This USB tool update is used for the first production run of ELITE models ONLY, and only once! All later production runs, and all updates after this first USB update, will take place wirelessly through the My JBL Headphone app, made for iOS and Android.

No. The only way that the Noise Cancellation feature can be activated is while you are using the headphones wirelessly. You cannot use NC while the headphones are plugged into a device or charging.

Yes, the two model 300 versions are of identical size, and so are the two model 700 versions. The carrying cases can be purchased as spare parts.

The app works with the Everest Elite models only.

Yes, ANC needs to be ON.

Each headphone is shipped with a micro USB charging cable. USB is the only way to charge the headphones, and all normal USB chargers may be used.

Sorry, neither AAC nor aptX are supported.

No, the tool will tell you to switch them ON when necessary.

It is not a bad idea to have the headphone charged before updating, but only if it is completely empty will there be any difference. To update via cable, a USB cable connection must be established between the headphone and the computer, and since the cable is also used for charging, there will be power to the headphone as long as it is connected to the computer. If the battery is depleted, it may be necessary to wait a little while, until a basic level of charging has been reached. Please note that the ELITE models with the most recent software permit wireless upgrade, directly from the control app on a smartphone. In this case, it is of course necessary to have power enough in the battery to sustain the whole upgrading process, since it takes place without cable.
