I bought it from accessoryjack , idk if they are "authorized dealer" , i'll contact both accessoryjack and sony, the problem is that i'm from Brazil, and i dont know if "Sony Br" will replace it, since it does not sell this product in my country, only the ma300.

i have the ma900 for about a month now, and i'm having some problems with "cracking sounds" , more like some snaps in the left ear cup, i think it's the cable, does anyone knows what it can be? It's really annoying sometimes :(

which one is better for female vocals : v-moda xs or ath es700 ??

I received my ma900 and found it to be pretty amazing directly from the xonar u3, but now i'm wondering how better it could be by using a dac like fiio e17 or e07k, i mean, the difference will be night and day, or just slightly better?

how bad the AKG K612pro will sound using only a asus xonar u3??

sony ma900 vs hd 600, better midrange? 

I'm from Brazil, not that easy to find deals on headphones, so i need to buy it from accessoryjack, to avoid extra taxes, thats why it's a little higher than the "street" price. So i guess MA900 is the best option under 300 u$ afterall. Thanks for you help :)

  How is the hd 598 bass response compared to the ma900? I'm not a basshead, but i like to feel the kick and details in the lower notes. The HD 598 will cost me 270 usd. And i saw a lot of ma900 > 598 in comments overall. 

i'm using only a xonar u3 + fiio e6.

Do you guys think it worth 290 usd, or should i get philips x1? I'm a vocal lover.
