Compatible with the MDHearing AIR 3 (A series) only.

Every MDHearing BTE hearing aid comes assembled with thin tubing (2B length). This discreet tubing connects the ComfortTIP to your hearing aid and provides you with clear, clean sound.

For optimal performance, the tubing and the tips should be replaced every three (3) months. Replacing these parts at the same time will keep your hearing aids feeling and sounding like new.
