Used many different brands over the years such as Hyper X, Rig, Epos. After using these for the last 5–6 months they've been better quality than more expensive headsets, I've got a really big head and after a long day of using them the clamping force can start to get uncomfortable.
Aside from that the sound quality of the drivers is crisp and clear, while still having adequate lows, it wont be your best bet for super heavy bass if that's what you're looking for but the bass it does provide is more than a lot of other name brands I've used. Battery life usually runs me about a day of solid use with the RGB on, Not a noticeable difference with it off as there's only one small RGB zone.
Mic quality is crisp and clear, friends have even noticed a better sound quality when I talk from my previous headset (EPOS with external soundcard)
So all in all my only real gripes are the battery life could be better, and the clamping force, which for smaller heads wont be an issue. I highly recommend!
