4th gen ipod wireless/bluetooth headphone options?

[maademperor]

Hi, I have a 30gig 4th gen Ipod video (I think its 4th gen), it doesnt have any bluetooth functions but I want to get some form of headphones that are wireless so I can stop bouncing it off the treadmill and exercise bike at the gym....do they make BT headphones that have thier own transmitter? If so, can someone link me up or provide some insight?
