Prog Rock Man: That's sort of my point - i probably could have had something sounding as good for around the 150-200 euro mark, although I don't mind paying a bit more for something so obviously well made.
hozo: I wouldn't dare try without the ear pads as it just a block of milled metal under there (uncomfortable!), but I don't think the holes in the pads are too restricting.
Just for info, although i was going to return them today, i finally decided to try them a couple more days. Tonight i went out for the first time on the subway, and i have to say, i was very impressed with the noise isolation. They blocked out most alot of background noise but you could still hear just enough (such as announcements or approaching trains).
One more thing i discovered since my last post: i tried them through my imac, iphone, and ipod shuffle (having previously only tested them through my ipod classic as that's what i bought them for) and it's made me realise the difference between the headphone outputs of all these apple products - It turns out my 80Gb Classic has the worst output of the lot.
