I've got a pair of Koss UR-40 headphones and they do not press your ears into your glasses at all. They're extremely light, have a webbed headband, are foldable, cover your ears rather than set on them and sound simply awesome. The sad part is they have no mic. If you want a great sounding pair of stereo headphones and don't mind spending a bit for them ($49.99 at Radio Shack, less online via Froogle) you can't go wrong. If you need a full on headset with a mic, well, I dunno.
