Stereo Bluetooth Adapters for Mobile?

I am looking around for a good bluetooth adapter for my android phone. Something I can plug a set of stereo headphones into so it will stream music to then but also be able to pick up calls.

So far I have seen the Antec AMP Gain http://store.antec.com/Product/audio/bxr-100-whi/0-761345-73031-0.aspx It looks about perfect but are there any other options out there? The gain for what it is seems a little expensive.

I have also heard of Ribbon http://www.myblueant.com/products/headphones/ribbon/ Looks really classy but is yet more expensive and seems to only be in America

I am in Ireland for currency and delivery info.
