Great headphones, and a good experience with wireless headphones. I will be moving to hyper x cloud flights though as the headphones do slip off the head in certain positions (more common than not). Rather than dealing with the hassle and discomfort for the next few years I'd rather use another headset. Apart form that, audio is great, form factor is ok (it still kind of has that hard pressure on the top of your head as similar to the G430s, had to return that aswell).
As long as I'm right in front of the PC they are great, if I wander around the house it does strange things sometimes. Initially there was an issue with the Mic not unmuting when the arm was lowered, but this has been resolved in a recent firmware. Reasonably comfortable on an adult head with adult sized ears.
