I've seen some great discussions on headphones around here, but does anyone have views on what they'd recommend in terms of headsets? You know, with an attached mic.

The choice out there, as with headphones, is a bit bewildering, and I'm having a hard time choosing mine. If anyone could help me I'd be very grateful.
Main criteria: under £100, great sound quality for music, 5.1 surround or greater, super comfortable (and ideally doesn't squeeze glasses into your cranium). I'd go for the Sony MDR7506 I've seen discussed on ETS lately, but I do really need that attached mic for gaming.
