There has recently been a sudden surge in the number of HD555s and SR225s for sale. What in the world is happenning? Most of them have hardly been used at all?! To me this is a good sign because people are beginning to upgrade at a rediculous rate these days. Both headphones are sort-of midranged in their respective company line-ups and probably represent the sweet-spot of their respective niche. Why are people selling them? I don't understand...
