HEARING AID COMPATIBILITY: The adapter should work with hearing aids that support the Bluetooth HSP (headset) profile.  It will NOT work with "streamer" style hearings aids that use the A2DP (streaming audio) profile.  You should contact your hearing aid manufacturer to find out which profiles are supported by your device.  NOTE that some streamer hearing aids offer an optional Phone Clip addon which will allow them to work with HSP devices.  Your audiologist can tell you if such a device is available for your hearing aid.
