I paired these headphones with a Sony bluetooth adapter (http://www.amazon.com/Sony-Bluetooth-Wireless-Transmitter-Black/dp/B000XRW09Y/ref=pd_bbs_sr_1?ie=UTF8&s=electronics&qid=1230418884&sr=8-1) for my iPod classic and it works really well. The headphones have the nice fabric/leather padding on the ear cups so if you run with them wipe them after use or else they could wear down and malfunction if perspiration gets inside the ear pieces. My only complaint is you need a good line of sight with your bluetooth device to get an uninterrupted music signal. I jog with these and my iPod is on my armband and every once in a while the music signal cuts out for a second when my arm swings too far back. Not a huge deal, but something to consider. Plus the headphones are weighted well so they move very little when jogging fast, unlike similar headphones of the same design. Very well worth the money and jogging without tangled wires is a joy!
