JBL Everest 700

It is possible to replace the ear pads, but there are details to consider. On Elite 700: The ear pads are held in place by a plastic plate with claws, and some of the claws will most likely break off when you remove the pad. You do this by grabbing under the edge where the fabric ends, then pulling hard outward. The claws will eventually let go, and some of them will break off, rattling inside the ear pod. The only way to get them out is to unscrew the speaker plate, lift it up, and shake out the broken-off claws. The new pads are simply centered over the speaker plate, and the claws pressed into the holes with a firm pressure. On Everest 700: The ear pads are glued into position with double-adhesive tape. Pull the old pads off with a forceful, steady pull, until the glue lets go. Remove the protective layer on the new pads, and carefully position them correctly before pressing home all the way around the edge.

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.

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.

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.

Yes , all 5 models have voice prompts. The Elite models have the added option of turning off the voice prompts in the settings menu of the app. The Everest 300 and 700, as well as the successors 310 and 710, have the option of choosing between voice prompts and tone prompts. This is how you do it: Switch the headphones ON. Press and hold the Shareme and the Volume Plus buttons for about two seconds. Switch the headphones OFF. You will now hear the OFF prompt having changed to the prompt you did not use before, and you will hear this one until you change it again.

For models E40BT and E50BT Connect the first headphone by BT to your mobile device Tap the ShareMe button once Tap the ShareMe button on the 2nd headphones twice ( ! ) The headphones will connect to each other. When changing volume on source device, or BT connected headphones, the volume will only change on THAT headphone ( and in some cases the source device, like iOS devices and newer Android ), not on the one connected via ShareMe. When changing volume on a via-ShareMe-connected headphone ( 2nd ), it will not change volume on source device, or on the BT-connected headphone. To sum up, both headphones have their individual volumes. For Everest models ( not ELITE ). Connect the headphones by BT to your mobile device Put the 2nd device ( speaker, headphones as long as they have Bluetooth ) in "BT discovery mode" Press the ShareMe button on the Everest headphone ( button marked with a little "s" ) The Everest will connect to BT device. (Please note that you may not be able to pair from the Everest to the Everest Elite models, or if you can pair, you may have dropouts in sound). When changing volume on source device, or Everest, the volume will only change on the Everest ( and in some cases the source device, like iOS devices and newer Android ), not on the device connected via ShareMe. When changing volume on via-ShareMe-connected BT device ( 2nd ), it will not change volume on source device or Everest. Please note that it is NOT possible to use ShareMe if you are listening to analog signal via cable. Bot the E-series and the Everest models will switch off the Bluetooth circuits as soon as you insert the audio cable, so re-transmission is not possible.
