Phonak Naida B hearing Aids. Carry case, storage case with instruction booklet. These have only been used for 1 month - my mother in law just did not use them. Great working order. The Phonak Naida B50 SP (Super Power) is a Behind-the-Ear (BTE) hearing aid designed for severe to profound hearing loss, featuring the Belong platform's SoundRecover2 for high-frequency audibility.
