Melomania 1 button controls are not working

Please make sure you are using the button control correctly.
See, 'Melomania 1 Button Shortcuts' article here for more info on how to use your Melomania button controls.

For the button controls to work, enough force must be pushed so that you can feel the surface being pushed down. Button controls do not work by tapping lightly on the surface. 

Reset your Melomania 1.
1. Place both headphones in the case.
2. Press and hold both buttons until the earphone status lights briefly turn blue.
3. At this point, you can release the buttons as the reset procedure is complete.
4. The earphones will no longer remember any of the devices that have previously paired with them.
5. You will then need to follow the initial setup procedure from scratch including the manual Bluetooth pairing process, achieved by holding down the earphone buttons for 3 secs to enter pairing mode.
