I received mine today. Would have taken a little more padding on the top and apparently I have a small head with those because my two ears touch the drivers. Gonna try to find thicker earpads. Fun fact: ear pads that fits on the ADH-AT900x will fit on the K553 too. I tried with the stock ones of my ATH but I lost any seal and the sound thus (and the bass became overpresent with the earpads of the K553 on the ATH)
