I bought these in Chicago O'Hare before I got into the Head-Fi hobby. I was looking more for a bluetooth headset solution but liked the way these sounded. After listening to Grados, Senns, and Audeze over the past few months I can say that these do give a quite satisfying presentation. My only gripe is the dongle and the wires the wires don't hang down, they just kind of stickout and get in the way. I would also like a longer cable from the earpieces to the dongle to give more attachment options.
