For any one that has a Nokia with stereo output w/ pop-port (6230 & 6620) this is the best accessory you can IMHO. It's the HD-s headset modded with a 3.5 female adapter. You can plug in a normal set of headphones and listen to mp3s, radio, and take calls too. If you are intersted, it was done by Vanilla8 over at HoFo. He dose lives in the UK, but was great with updating me & it took about 7 days to be shipped to me. The price was $35 USD (thanks to the weak $), but well worth it.
