Pair of Sony headphones I borrow a lot for music making.
I found them uncomfortable to wear for long periods of time, like too much pressure builds up in my ears. I got some soft, fuzzy 'velour' pads made by Geekria that've improved things. Seen people say they effect the sound negatively, but I haven't noticed.
Before that the original pads had got all flakey and I'd replaced them with pleather ones by Brainwavez. Lots of replacements say they're leather, but I think they're all lying, they'll probably all go flakey eventually, depending on conditions/climate.
