GA22L is a non-conventional glasses hearing aid that rids the stigma of big bulky glasses instruments. GA22L is actually a hearing instrument that adds on to a user's existing glasses. It can be adapted to the glasses frame easily and is available in open-fit configurations. For those needing more gain, it can be fitted with a traditional earmold. Highly advanced features make GA22L a must for those with both sight and hearing impairments.
