So I got the Pioneer HRM6 and the Superlux 668B in today. The Pioneer I can't say how they sound like because they came without a cord, from ebay, and I don't have a cord that fits. I have a 2.5mm to 3.5mm, but it's too thick along the casing part. So I ordered one I hope will fit for a heck of a lot cheaper than the $30 pioneer wants for one of theirs.
The superlux though I am listening to. OMG these things are bright and fatiguing. They are clear, and sort of better sounding than the muffled, dark, veiled crap of "gaming" headsets. Still they are way worse to me than the 681 Evos. They are very plastic and don't inspire durability at all. Given the choice between the two for about the same price I will without a doubt recommend the 681 EVO over these 668Bs. That's not to say they are horrible, just not my cup of tea for the price. Speaking of which, they don't fit my head really. I'm serious. I have to bend the "flaps" of past the headband because they don't fit on my head otherwise. With the flaps out of the way my head is touching the rubber coated metal band at the top all the way around. The clamp is still bit tight, but looser than the EVO's out of the box. The pads are the same size, but the velours are stock on them. So my ears touch, but there is a bit more give to the cushion as well. How the flaps touch the top of the head, when not pushed out of the way, isn't comfortable for me. Those flaps actually feel really weird. Good thing I got a deal for these at $20 instead of the normal $35-$40 price.
As for the HRM6s, the build and comfort are what you'd expect out a higher premium headphone. Just wish I could listen to them right now as well.
