Having had various helmet brand before Sades (including Plantronics and Triton) I turned to Sades which, from what I read on comments, was a very good gaming headset cheap. I'm not disappointed at all and even if prolonged use of several hours is slightly earache (which is recommended regardless of the helmet brands anyway), it is very comfortable, the controls are very convenient to increase / decrease the volume and mute the sound or microphone without touching the keyboard when were playing. Better yet tested on Linux Ubuntu 14, the headset works very well, but we must of course go to the sound settings and activate the "USB Speakers".
I recommend this helmet for those who want quality at average price!
