DefQon is correct, they are semi-open. Turned up, my wife can hear what I'm hearing...but not Stax SR-009 open naturally.
Edit: I forgot to add a few more misc notes :-
1) little isolation
2) can drive off my iPhone 4S (50% vol for me and I kinda listen semi-loud-ish)
I asked the distributor but the pricing is still unknown at the moment.
Tell us more!
