Firstly anyone who plans on buying it should know that the company which makes this is going out of business. When this product was introduces in the CES exhibition a couple years back it was one of a kind and hailed as a brilliant product and cost around $80.As to which IPOD's it works with I have used it successfully with my new Nano 8gb and the 8gb touch without any problems. The pairing is pretty easy and the manual is quite adequate just make sure you press the button for a few more seconds than what they say in the manual.Pros:-Supports play,pause,next and prev functions from your wireless headset-Good finish and build quality-Works flawlessly with my Southwing SA505 stereo headset-Decent battery life-Can be used as a docking station to charge your ipod.-It has a bunch of clips to hold ipods of any size in place.-The cheapest bluetooth transmitter I foundCons:-A little chunky(base is about 1"X1"X2.5") but I have not come across a smaller bluetooth transmitter-Only works with ipods and maybe(iphones) the connector is not a generic one but I guess that is the nature of the beast a generic plug will not let you control the music player from your headsetAll in all it is an amazing deal for less than $10. I have had no problems with the streaming or sound quality.
