If you wish to factory reset your Melomania Touch:
Place both earphones in the case.
Press and hold on both earphones for 10 seconds or longer until the earbud's LEDs start flashing white rapidly.
At this point, you can release the surface of the earphones.
The earbud's status lights should now briefly turn blue, which means they are in the process of factory resetting.
Once the earphones have stopped flashing, the reset procedure is complete and the earbuds will no longer remember any of the devices that have previously paired with them.
You will then need to follow the initial setup procedure from the beginning.
