Wireless Headphones For Ipod touch 4g

Hi,
I was wondering if you need an ipod adaptor to use wireless bluetooth headphones.

I have the new ipod touch 4g and i want to buy wireless headphones.
i was wondering, do i have to buy an adaptor .....since the ipod has bluetooth itself?

Also, what are the various things you can do with the bluetooth of an ipod touch 4g?

Thanks for the help
🙂
