Very good, but can do better
Excellent helmet!
If I had to compare the G PRO X2 to my old helmet (Arctis PRO) :
The comfort is much better with the Logitech, in terms of my ears which are well covered by the headphones, I can spend 5 hours non-stop playing without being bothered by the cushions or the pressure of the headband on my head.
This headset is recommended for people with large heads, as the Arctis was much less comfortable and after two hours of gaming I was bothered by the headband AND the cushions putting pressure on my ears.
In terms of audio quality, the G PRO X2 is still decent but suffers from a lack of mid-range in the spectrum.
Where the Arctis could play music and gaming, the G PRO X2 is much more geared towards gaming.
If you're an audiophile and want headphones for playing games AND listening to music, I wouldn't recommend the G PRO X2, but if all you want to do is play games, then it's perfect for you (which is my case).
