Turtle beach headsets are horrible... I walked into a store that had them on display so that you could test the sound quality of the different heasets and tried them all on.
First off, I could barely tell the difference between the high and mid range ones, even though there was big signs saying "Superior sound quality" on the highest priced ones, and the price was outrageous...
I have a 40 dollar cruddy headset and it sounds better than those turtle beach ones.
Hopefully the ones they make for the One will be better than those for the 360, and I hope they aren't priced so outlandishly. I can still see them making bucketloads of money though, after all, their target audience (Or the majority of buyers) are young people too wrapped up in the yearly COD releases to pay attention to how they spend their money, or have any idea what quality control is... Its a shame.
