As a budget product from Turtle Beach it's good.You can actually hear sound cues you would'nt pick up before.Quite comfortable for long use,fold up neatly for storage,long cable can be annoying,but you need it.
Now the cons,incredibly difficult to set up to hear both game and chat for on-line gaming,but with a bit of persistence you CAN get good results,contrary to other reviews.
Here is what you do.Say for example Modern Warfare 2,and actually nearly every game I set up.Go to system settings in the xbox menus and turn voice chat level all the way up.Set sound playback for both speaker and headset,this for the voice chat channel.
Then go into the game main menu.Set the master game volume,effects, music etc to 1/4 or below,sometimes just above OFF.I know this seems low but trust me.As the voice chat level is still low even when turned all the way up in the xbox menu,you have effectively set the two levels just about equal levels (fine tune it to yourself) .
Then you just turn up your tv with the headset plugged in and it should ballance game and voice chatter to good levels.You may have to do this a few times,and as most games volume control is in the main menu and not useable from on-line lobbies you will have to duck in out a couple of times.When you do this wear the cans "half ear" so you don't blow your head off if you get it wrong!!!!
Don't forget to turn the in-line volume control to half way then you can adjust to a comfortable level.Hope this works for you,as it is a pretty good headset overall for not too much dosh.
