Astro A40 or Razer Tiamat

I cant decide which one to go with, I only play on PC, but I listen to alot of music, and movies on my speakers so the way the Tiamt has that easyswitch, where I plug my speakers in the box (the one with the volume contorl and such) that comes with the headset, but I have heard that the Tiamat has alot of problems and the Astro has gotten alot of good reviews. Sorry for if it didnt make much sense, I am from Norway
