The TB PX5 are not that great for the price your paying. And they operate in the 2.4Ghz range, so you will get a lot of interference. Look into astro a40s(A little out of price range you want to spend but amazing) or possibly the a30s.
Personally i have owned TB 4x, TB 41x, Tritton AX Pro, Tritton AX720s and Astro A40s. A40s have it for overall quality and I would say the old TB 4x would be second. I had alot of problems with the TB41s and the Tritton AXPros and with the AX720s its just lacking the high end sound quality. So it really just depends on how into gaming you are and what your buddget is.
I do have the new Tritton Warheads on Pre-order but we will see if they ever actually come out!!!
