I have the Turtle Beach x41. Thanks justinsanev2, I might pick up the xp400. There are only 2 issues with the x41 I hate and it's the pops/clicks and the xbox live chat cable, I'm glade to see they are fixing that with the XP lineup. I always seem to pull the chat cable out while I am talking or someone is talking to me.
The pretty penny you spend to them should get great use though! I wouldnt recomend a casual gamer to get the TB XP500's or Astro A40's but if you have the money go for it! I put plenty on time on the X BOX every night so mine have got the money's worth already haha
I've watched YouTube video's that compare the two Wiggy, and they both seem just alike, but then again it depends if you are a TB guy or prefer the Astro way. Either way you're going to end up with a great headset!
