I am sorry that you're unable to get audio from the left earcup. I would love to do what I can to help you.


Does this occur with both a cabled and Bluetooth connection? 


Lets try resetting your headphones; 

  • Disconnect all cables from your headphones
  • Connect the larger end of the USB charging cable to a wall charger or a computer that is powered on
  • On the headphones, press and hold the Power/Bluetooth® button while connecting the smaller end of the USB cable to the right earcup. The Power LED should quickly blink twice
  • Once connected, release the Power/Bluetooth button after two seconds.

Following this, check for any available firmware updates for your headphones. This can be done via a computer using a USB and visiting our firmware update website, which will provide you with full instructions.


Do let us know how you get on.
