Sennheiser HD280 Pro

Pros: Comfortable ear cups, great isolation, proper cord length for office, excellent all-around sound for all types of music

Cons: No headband tension adjustment

Summary: I work in an R&D office adjacent to an automotive/fabrication shop. These HD 280 Pros isolate the air impact sounds wonderfully. Largely listening to trance/techno/house, I found these to be accurate, clear, and responsive to all frequencies. The sound is linear at all but the highest levels. I sampled the Eagles and Norah Jones to get a feel for the fidelity and was impressed at the audible nuances that I was missing. The design is basic but well-built. The headband is comfortable, albeit an adjustable tensioner would be nice. Faux leather ear cups are supple and my big ears don't hit the inner linings whatsoever. Coiled cord length is great for PC or MP3 player use. The screw-on adapter is a nice finishing touch on an excellent pair of closed ear headphones.
