I would appreciate any recommendations for a sealed, over-ear, isolating headphone to be used in a relatively quiet open office setting. Priorities in decreasing order are sound isolation (including keeping sound IN), comfort for hours of use, price, and sound quality. I don't like IEM or on-ear phones.
Also looking for something that I don't think exists: a USB dac/headphone amp combo with tone controls and (yeah, right..) a loudness contour control. Source is most likely a PC, maybe iPod.
At home, I use a Benchmark dac driving Sennheiser HD650 phones.
