Sony MDR V250V headphones

Bought a pair of Sony MDR V250V headphones after realising that the time is up for my (cheap) Philips headphones. The Sony has everything I needed; it had rotating speakers, was lightweight, compact, and cheap ($50 after bargain)! I'm not sure if the Sony speakers lying on my ears rather than covering them would cause difficulty when I play for 4 hours or more at a stretch though. I chose the Sony over a Senheisser HD 212 which went for $100 (after discount from $115). The only possible advantage the Senheisser could have had is better sound quality (which for me is not that important when beatmatching on headphones), since the Sony is more compact and versatile and black in color (which I preferred over the silver Senheisser).
