What do I do if my MW75 headphones are not playing any sound?

The following step-by-step instructions should resolve most audio issues: 

  1. If you're using your headphones with wired audio, please be sure the cable is secure in the USB-C port. If you're using your headphones with Bluetooth® ,  remove – or "forget"  -  the connection with your source device (and any other devices to which it might be connected).
  2. Cycle your headphones OFF and then back ON
  3. Please check the number of Bluetooth®  devices with connections to your source device.  
    • Even if not currently active, more than 4 or 5 Bluetooth®  connections can cause issues with connectivity. 
  4. Remove - or "forget" - all other connections to your source device, and connecting only your headphones at first.
  5. Reconnect your MW75 headphones and test the audio again
  6. If you haven't already, please install the "M&D Connect" app on your mobile device 
    • Once installed, connect to your headphones in the “M&D Connect” app 
    • Perform an update to the firmware via the app, if available

  7. If you're still having trouble, check the following:
    • Does the issue persist across multiple programs (for example, does testing with music players, phone calls, and other apps all produce the same result)? 
    • Does the issue persist when connected to another device (if you're using your mobile phone, for example, can you test it on a computer)? 

 If the above steps do not resolve your issue, please try a factory reset.

 If you're still experiencing audio issues after completing the factory reset, please submit a ticket, and one of our representatives will be able to assist you further.
