JBL Everest firmware update #SoundGeek

Owners of JBL's good-but-flawed Everest headphones have long-complained of the processing lag that prevents sound from being in synch with video when pairing with a TV or watching videos on a mobile device.  JBL previously addressed this with a firmware update (yea!) but then, without explanation, removed the update from various product support pages (boo!)

If you have "normal" (i.e., not "Elite") Everest 100, Everest 300, or Everest 700 headphones and have sound lagging behind video then you're in luck:  I have located the elusive firmware update over on JBL's Japanese site.  The site isn't in English but the firmware package itself is and includes English instructions.

Here's the link to the firmware:

(updated link March, 2021 - thanks commenter rteng!)

I was able to upgrade a set of Everest 300 headphones from firmware v1.1 to v3.1 with no issues (via USB connection to a Windows 7 PC). The update fixed the audio lag issue for me but your mileage may vary.

Cheers!

    Firmware appears to be gone from that link. Any ideas where we can get it now?

      I can't say that the following version of the file has the same upgrades for the normal Everest series headphones, but you can give it a go:

      Please post back with success/failure. Good luck!

    Download the tool from here:
    https://www.jbl.com/V300BTCBU.html --> "Manuals and Downloads"
    The latest version is 3.1

    I can confirm that the update linked in your Feb 1 comment works with my Everest 300 (non-Elite) and updated from firmware v1.1 to 3.1. It fixed the annoying lag!

      Glad to hear the post info/link(s) are still helpful. Over two years on from updating the firmware I am still enjoying my own Everest headset. Thanks for the feedback!
