The HD280's attenuate 2-4 more db than the Extreme Isolations, are lighter, more comfortable, and sound better, with better bass response. They are backed by a big company with a long history of customer support. Aside from that, Extreme Isolation's ambience is nil. For that video or photo op, I can tell you, you will *not* wow the groupies with those butt-ugly headphones! Admittedly, the Sennheisers cost $20 more. Just cough it up.-Richie
