Has anyone tried the Beyerdynamic 770 pads on the he-400? I noticed that the Hifimans velour's fit onto the M-Audio Q40s, they sound quite nice btw. I found this while I was waiting for the Beyer pads; a recommended replacement on the Q40. The Velor pads of the Beyer has all the holes already and they are the same size except for the vinyl that wraps around the hifiman mounting ring. The Beyer vinyl is about a quarter inch shorter but should still fit the ring. The dust cover (which is not attached) would slip under the pad.
I'm not sure if the Beyer pleathers have the holes. Beyer also has gel pads for the 770. Makes me wonder. <shrug> Jerg pads without the cutting?
