These are perfectly good but old technology hearing aids. I paid $3,400.00 for these new. They use batteries and are not rechargeable. They are not adjustable but if you have a audiologist perhaps they could do that for you. Comes with 6 packs of batteries and extra replaceable ear cups along with original instruction info.
Include phone number with inquiry as I will not respond to emails. Too many time wasting scammers out there.
Thank you
