So I just bought the Turtle Beach X11 out of recommendation from a friend.
Terrible, never buy them.
They sounded like stuff, I listened to a song earlier today with pretty good quality and when I listened to it with the headset it was terrible. There is a constant buzzing in the background, even with the microphone off, there are random pulses of noise like electrical cracks every few minutes. The sound was so out of balance when I played Left 4 Dead 2 it made me want to stab myself in the ears. The microphone was also pretty stuffty, though not as bad as the rest of it. Dear god, I can't imagine what the X1 was like.
Taking those forgeters back tomorrow and buying real headphones. The list of features and stuff? That was just polish on a turd.
I mean holy stuff, those things were not worth even close to $60.
Curse-ridden rant over.
