I’ve never heard of the Game Zero. If it’s what it sounds like, a new budget spin off of the Game One, then I think it could well be shit. I’ve owned and really liked the GameOne, but Sennheiser sold off its gaming headphone division a couple years ago (why they’re “EPOS” now), so if they’ve designed something new, they haven’t necessarily done it to Sennheiser’s standards, and it’s deliberately cheap and directed to gamers. All red flags.
