I used to have the Turtle Beach X12's for about 3 years when I was a console gamer, when I found out that the sound quality on PC wasn't that good, I bought the HyperX Cloud I's.
This is from my own personal experience, and not influenced by reviews/critique:
- The sound-cancelling is incredible. You can really focus on your game (footsteps, minor sound output, etc.)
- The microphone quality is good for gaming/VOIP, but not incredible for broadcasting/commentary.
- They are REALLY comfortable. With the headset I had, you had the choice of leather or those plasticy type ear-cups.
- The sound quality is really good; although you WILL need to apply a bass-boost through Windows Audio Mixer, as the HyperX's don't have natural bass boost.
- Above all, IMO, they are affordable; and a really good place to start with PC Gaming.
tl;dr - Awesome headset, affordable, the microphone is good quality, but I opt to use the Blue Snowball for recording, not the headset microphone.
If you want to hear a soundtest or something, feel free to forum PM or tweet at me.
Hope this helps!
