I will need more time with them (and time to write) in order to give a full review, but i spent a few hours with them yesterday. Holy crap. A. yes ,they sound smashing right out of the box. (so much so that i find it hard to imagine how much more they could improve from burn in.) B. wow, they sound better, far better than any closed can i've used yet. They sound almost as good as my HD 598's, and the soundstage seems almost as wide. Which is just impossible to believe. But the raves are true. They are amazing. I'm using them with my Fiio E07k with the bass tweaked to +2.
I *am* having some comfort issues. They are heavy, but the issue for me is the clamping pressure..my head is big and on the most open setting of the band they still clamp rather forcefully. this aids the seal, but i'm hoping they ease up a bit with use. However i did fall asleep with them on in bed last night so they can't be *that* uncomfortable!
I will attempt a full review after some time with them, but initially my reaction is WOW...the folks who described them as "shockingly good" are right. I'm shocked by the sound, the clarity, the presence and the soundstage. I can't imagine any other sub-500 (let alone sub 400) dollar closed can sounding this great.
