How do I check/update the firmware version?

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  

The app will inform you if an update is available. Firmware updates require headphones to be charged to 60% or higher.  Audio playback, phone calls, multipoint connection, charging, and wired audio will not be accessible during the firmware update.
