Due to the difference in design between the M100, M1/1+ and Melomania Touch earbuds, foam and silicone ear tips designed for use with the M1/1+ and Melomania Touch will not fit correctly on the M100.
While the Melomania Touch silicone ear tips will be able to be attached to the M100, we do not recommend using non-M100 ear tips as they could come loose from the earbud and get stuck when removing the M100 from your ear.
