Well, I just can't quit these headphones:P. Just got my third pair in today. If you've read what I've previously posted, I did some pad swapping, and I had settled on Beyer velours, but they kind of imparted a bit of a dry sound to the HP100s, which wasn't perfect, but worked okay. Well, with the pair I just got today, I happen to have a pair of Custom One Pros right now, so I decided to try their pads, even though I've tried the softskin pads before (which appear really similar to the COP's pads), and the results weren't very good. So imagine my surprise when I try the COP pads, and they don't sound hollow or muffled, which were my impressions from trying the softskin pads previously. I haven't tried the stock pads yet on this pair (swapped 'em as soon as I got them today), but I'm pretty sure the bass has been increased from stock. However, the clarity remains, and it only hits you when there's bass in the song. A pretty lovely, warm sound. Additionally, the cool thing about the COP pads is that there are replacements in several different colors, so you can customize the look of the HP100s, which is pretty neat. I think I'm going to go with the brown or black pads. Hope this helps.
