I like the Trittons, but they are kind of one the heavy side. Turtle Beach are lighter on the head, but from what I read on reviews, they don't sound as great (but are still very capable).
If I were you, I would go down to your electronic store and try them. Stores like Best Buy usually have the TB headsets, so you could try those. They sometime have the Trittons, but not always. What you could do is try the TB on, and ever try them in-game if they have a display booth or something. The main thing when it comes to gaming headset is comfort. For me, the Trittons are great. Others find them heavy. It's very subjective, so try them out if you can!
