Good review, agree 100%. I wish they had made them a little sturdier, but they are super light and comfortable as is.

and they say this can beat the hd598 bahaha
sony should focus on gaming

Well i didn't hear the HD598 yet but IME the MA900 stomps all over the HD595 i had a while back... haha.

Great review I would totally support the idea of an updated version of the MA900... MA1000? :3

Sounds like it would pair well with the iCAN amp which works very well with headphones that need a little extra low end and detail:

I'm impressed with the length and detail of the review, and agree with much of it. Thanks for the effort.
I give these headphones higher marks for sound quality and design, design which I think borders on the brilliant in the way it produces such full sound from such a lightweight frame.
The SQ, IMO, is exceptional; pretty much top of the class in this price range (which is $298 list although often available for significantly less than that).

it must have the same 70mm drivers that they put in the xb1000

^How so? No indication beside the same diameter.
Zazex, I agree with you on the part of the admirably robust sound for such a minimal and open frame and i did stress that point myself (end of second paragraph). That said, when judging in absolte performace i find them to be warmer than i like, i prefer a faster transient response myself. Then again, it's my prefenrce only and for those who like the warmer approach it's indeed a stellar bargain, espcially at the below 200$ mark they currently go for. Btw, I'd give them another notch up in SQ withthe compensation circuit removed, It does clear the sound slightly.
