Bluetooth to what, a phone? If you want a water resistant phone, the Motorola Defy is the only one out there right now that can take a beating with h2o.
I have Naida. It is water resistant. That is a different thing than waterproof.
Siemens Aquaris is a waterproof hearing aid.
But your restistance ha's can you still possibly swim/shower with them? N do u have any remote/accessories?
I've seen videos on Youtube where some people are swimming with their Aquaris hearing aids.
