I love HM5 pads. My ears are tall, and I've tried fewer than a dozen headphones that are actually circumaural for me (most of which are Sennheisers). The HM5 save me on many potential headphones because they actually fit.
I own pleather, pleather angled, hybrid, and velour. The only ones I don't have are angled pleather but I've been thinking about trying them with my HD650s.
I also have Lawton pads (he gave me the biggest of a batch) and might grab Audeze pads as well. I roll pads like some people roll tubes.
Even Fostex and Beyerdynamic pads don't fit me, but the Brainwavz pads do.
By the way, they do fit on 650s, but you'll likely destroy the original pad's harder plastic part getting them off the ring. I managed to get them off and on again but the back looks ugly (not that you can see it when they're attached).
