How much do you want to spend?
And how good do you want the quality to be?
Unfortunately, the range of wireless headphones is still fairly limited... Granted there are quite a few products, but 99% of them still use Blutooth v1.2 which to be honest, is crap.
In my opinion, if you can't get a set that uses Blutooth V2, don't bother.
Then again, i'm a bit of an audiophile so i'm quite picky with my quality...
If you want a decent priced set, I would recommend
