My biggest problem with this is that it has a non-standard headphone jack. So I have these really expensive BOSE headphones and I can't use them.

I bought some adapter, but it really works poorly.

Can someone tell me what they did, of if the answer is bluetooth, recommend a good set of bluetooth headphones for listening to music? I am an audiophile so the quality of the sound is important, and I also like over-the-ear headphones.

I am in the UK.

I used a company called Expansys and purchased these

Hopefully they have a branch where you are. If you wish just search the site for balckberry earphones.

They work brilliantly by the way.

Those will be available in the US by end of month for $29.99. Here's a link from blackberry's site:

I'm waiting on these as well but have no idea how well they work.
