Hi, just a quick mash-up of what I wrote somewhere about HD 25.   *Clamping, isolation - When I'm commuting for almost 4 hours it can be quite annoying. On the other hand I was angry that my ATH-SJ5 has weaker clamping force after a year, thus less isolation, it would easily fall off, so I should be happy with what I have now. The only problem is that I have to have full-sized, cheap headphones in both places where I live during the week. Otherwise I'd have to buy 2 good home headphones, or carry one with me while commuting between those 2...
