Affordable Hearing Aid

Superb Performance From Affordable Digital Hearing Aids

Board-certified Ear，Nose，and Throat physician Dr. Cherukuri has done it once again with his newest invention of a medical-grade，ALL-DIGITAL，affordable hearing aid.

Dr. Cherukuri knew that untreated hearing loss could lead to depression，social isolation，anxiety and symptoms consistent with Dementia and Alzheimer's disease. In his practice he knew that many of his patients would benefit from new digital hearing aids but many couldn't afford the expense，which is not generally covered by Medicare and most private health insurance policies.

Same Technology as $3，500 Hearing Aids

He evaluated all the high-priced digital hearing aids on the market and then created his own affordable version-called MDHearing Aid AIR for its virtually invisible，lightweight appearance. This doctor-designed digital hearing aid delivers clear sound all day long and the soft flexible ear domes are so comfortable that you won't realize you are wearing them.

This new digital hearing aid is packed with the features of $ 3，500 competitors at a small part of the cost. Now most people with hearing loss are able to enjoy crystal clear，natural sound-in a crowd，on the phone，in the wind-without "whistling" and annoying background noise.
