i bought this pair for alternate use with my iGrado. (iGrado is less comfort for a long use).    Audio sounds better than the closed-back AKG K450, Senn PX100. i love the balance sound which i think is comparable to iGrado and Koss PortaPro. Design wise, the AKG420 looks more sturdy than the Senns, even though the portability of the latter is better. The denim and matte finish together with nicely placed AKG logos on both cups are very easy on the (my) eye. Size is neither too small nor too big, and rest comfortably on both ears after adjusting...
