Update on my Westone W30 review.
My brain has burned into them totally now. They're awesome, reallyl. I listen to a lot of rock, metal of all kinds, pop, rap, Type O Negative - it just all sounds awesome though my Cowon D2+. I also use them to record guitar into my DAW at home - this way I can mic my amp and not have to hear the amp, but only the mics I'm monitoring (the gun range ear muffs I wear also help). Great isolation with the foam tips that fit best. I mean, they cost $400, but if you can afford that I would not feel guilty at all about telling you to buy these. I've only the UE Superfi Pros (pre-logitec) to compare these to and I loved those. At first I thought these W30 lacked bass. Now I can't seem to tell, because I'm burned into them. Anyway, I'm all settled into these and they're awesome. I like they way they wear, too, with the zip cable behind your neck - people can't even tell you're wearing these - their lips move when they talk to you, but they don't know why you can't hear them. I'm spoiled to be longboarding around Seattle with such good sound.
