Turtle Beach is a very poor performer. Their products are mainly targeted at 12 year old COD players. I've owned the Logitech G35's for 3 years and they are outstanding. The noise isolation is very good, the bass is punchy and the 7.1 surround sound emulation is pretty good for movies (not music). Only recently have I noticed it dropping in performance (due to it's age no doubt). I haven't listened to the Razor, but out of the Logitech and TurtleBeach cans, G35 wins hands down.
