I think the a900x sounds better when it comes to video games. I had both for about 2 weeks and ended up returning the akg 550s. Build and comfort the 550s win for sure but im starting to get use to the a900x.   The bass and sound stage just seem better on the a900x.

thanks for the info. sounds like im good with the a900x.

Anyone ever try these out? I have the a900x and they sound great but wanted to know if these sounded any better. Please give me some info if you heard these before. Thanks!

thanks for the info. i will try it without it and see how it sounds. 

this is how i have it now. hdmi from ps3 to receiver and hdmi from receiver to tv. Im a noob when it comes to headphones. so you think i am ok without the mix amp?    thanks for your help. 

so i need to get one of those mixamps? 

I might just get the a900x. Ive been hearing good things about these and the akg's. I need a close end headphone that doesn't leak to loud. I have a loft and my gf goes to bed early. Reason why i need good headphones.    I think my receiver supports headphone surround sound. its pretty high...

thanks for the info 

I'm looking for the best sounding headphones for gaming. I play ps3 and will be using them on the ps4 when that comes out. I heard these are some of the best gaming headphones for their soundstage. I was leaning towards the k550 but now im leaning toward the a900x or the dt 770. Tough deciding...
