Can anyone supply a link to buy these in the US? I usually buy off Amazon but the 668b and the (rebranded?) Samson SR850 seem to be unavailable on the mainstream sites I use.
Also, could someone comment on the 668b's noise leakage? I read another review on this site that said the noise leakage was surprisingly low for a semi-open headphone, so low that it could be used in a library at reasonable volumes. If I was gaming in a relatively quiet room, would it disturb others in the room?
Also, I would plan to use these with two PCs, one is integrated audio, the other has a sound card with a built-in headphone amp. Will these drive the phones fine?
