HOW WILL I KNOW WHICH WIRELESS PHONES ARE HEARING AID
COMPATIBLE?
The Hearing Aid Compatibility rating is displayed on the
wireless phone box.
A phone is considered Hearing Aid Compatible for acoustic
coupling (microphone mode) if it has an “M3” or “M4” rating.
A digital wireless phone is considered Hearing Aid Compatible
for inductive coupling (tele-coil mode) if it has a “T3” or “T4”
rating.
