Please don't fall into that trap! Go in for Receiver-in-canal rechargeable hearing
aids. You can get a decent pair for about 65k. The cheaper ones will cost you a bomb in the long run in recurrent battery and servicing costs over the 5 year life of the hearing aid! When you purchase hearing aids, you should treat it as a 5 year comprehensive contract with the audiologist and get that promise in writing from the center. My audiologist even offers upgradation exchange discount after the 5 year period.
