Volume limiter was good and the reason we purchased 2no. of these for the kids.
At first they worked OK but even from the start they quite often had connection problems over USB (typically microphone stopped working even though the physical switches hadn't been touched (note the physical build quality of the switch box is not great). After about 2 weeks one pair is having to be returned - one earpiece is not working (seems to be a connection problem in the physical switch as it can work if the wire is wiggled.
Given the number of poor reviews I suspect quality control is not brilliant. Shame as they seem to be the only volume limited gaming headphones available
