There are some earphones that use bone conductance, but this sounds like a special case.

If hearing is down to tiny hairs in your ear resonating with the audio frequency, I would have thought being hard of hearing was down to those hairs not being able to function properly. How does bone conductance audio get around that? Does it use a different sense?

My eyesight is also going, I have to rub my eyeball on the phone screen like one of those anti-deorderant balls, I daresay my hearing will be next.
