Are you used to wearing aids? Like have you worn them for several years? I remember when I first wore hearing aids it sounded like really tinny bluetooth speakers hovering behind my head. It was distracting and a bit depressing to think this was what I was going to have to listen to.

Over a few months my brain priced it in, and now I don't get that at all. Putting them in just means I hear better. It is like my brain has noticed the new sounds and interprets them before I hear them. The audiologist I spoke to said this happens to everybody, however the longer you've had untreated hearing loss and the older you are, the longer it will take your brain to adapt.

I think they sound ok. Even when used as a Bluetooth headset for music there's enough bass that I haven't really thought about it.
