Compatible with the MDHearing AIR (M series), PRO (M series), and CONTROL models.

Our exclusive earhook and 13PLUS tubing is a wider tubing option, allowing a higher volume/more gain. This tubing also allows a custom length—it comes in a single size and you must trim it to fit your ear.

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.
