Can anyone provide recommendations for a Bluetooth adaptor for an iPod (Classic) - preferably one which provides more than just an audio signal (ie, allows track skipping and volume control)? I've seen some on the web, eg TradeMe, but haven't found much information on them.

Also, would be useful to know if any are paired with a decent pair of bluetooth headphones, or I'd appreciate some recommendations of any pair of decent phones that would work with such an iPod adaptor and a cellphone (preferably at the same time).

Generally, is the quality (both audio quality and strength of signal) ok with these products?

Many thanks for any thoughts.
