In order to listen to your music collection from your iPod to Bluetooth Headphones your first need to make your iPod Bluetooth-enabled by connecting a Bluetooth transmitter (adapter).

There are 2 types of Bluetooth transmitters:

1- Bluetooth transmitter specially designed for iPods with a dock connector
2- Universal Bluetooth transmitter that will connect via the 3.5mm audio jack (wired heasets output)

You should pick up the latter if you want to make other audio sources Bluetooth-enabled: CD/DVD/MP3 player, laptop, desktop, TV, radio,boombox, etc.

Now you can either pick up the transmitter (for iPod or universal) and the Bluetooth Headphones of your choice, or select a Bluetooth Headphones that already comes with a transmitter, made for iPod (dock connector) or universal.
