Just got a set of the Senn HD 280 pro's and returned them the same day.
Big 5 db drop in the midrange starting at 2.5k up to 10k.

How did you measure this?



While the 32db claimed isolation seemed to work they were very
uncomfortable to wear. Replaced them with another set of Sony 7506's.

Different 'phones for different heads. I find them tight but
manageable. Anything less tight lacks isolation IME.
