Barely noticeable while gaming. Rhythm games for sure, but otherwise my biggest complaint is that all 2.4ghz headphones are "gaming" headphones. Not many low latency high end options.
Unfortunately, my game is not a rhythm game. I basically can't tell which of my shots hit the target. If I shoot 3 times in 300ms, I don't hear the first shot until I click the second time, so if I miss the first shot, it sounds like I missed the second shot, it's very jarring
