Orient the earbuds so that the microphone is facing towards your mouth
Due to the cylindrical shape of Melomania 1, it may not be obvious that the microphone is facing towards your mouth. This makes a big difference to voice quality.
To ensure the correct orientation, ensure the Cambridge ball logo is upright, with the microphone hole on the bottom facing down.
