We carry demo models of all the hearing aids we sell. Like the library, you can "check out" an aid for a couple of weeks to be sure you love your aids! We cannot loan a custom aid, but we have all the RIC (Receiver in Canal) and BTE's (Behind the Ear) styles that you can try out. Nearly all the newest technology will connect to smart phones, which is really wonderful. Simply download the free manufacturer app and you can use your smart phone as a remote, or even set the aids up to hear your phone calls through your aids! Rechargeables are the way of the future. Nearly all brands have rechargeable aids, and patients love them!
