• What do I do if I can't pair my MW75 Neuro headphones to my device?

  We understand how frustrating it can be when your headphones are not pairing properly. The following step-by-step instructions should resolve most pairing issues.

  1. First, make sure the headphones are charged.  
  2. Cycle the MW75 power  OFF and then back ON.
  3. Turn the Bluetooth® OFF, then ON again on the source device.
  4. Turn OFF the Bluetooth feature on any other device that is paired with the headphones (phone, computer, etc.).
  5. Hold Power/Pairing button down for 4 seconds to enter pairing mode.
  6. Make sure “M&D MW75” is selected in the Bluetooth device list. 

  If the above doesn't work, please try a factory reset.

• What do I do if my MW75 Neuro headphones aren't charging?

  To make sure the charging issue is not a result of a faulty cable or charging source, please test using another cable as well as an alternate charging source (for example - if you're using a computer USB connection, try a wall charger instead). 

  If using alternate charging methods does not work, there are a few other things we can try. 

  1. Cycle the MW75 power  OFF and then back ON.
  2. Turn the Bluetooth® OFF, then ON again on the source device.
  3. Turn OFF the Bluetooth feature on any other device that is paired with the headphones (phone, computer, etc.).
  4. 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

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

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

• What do I do if my MW75 Neuro 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.
