ANC Performance and Battery Life

The ANC does a good job of filtering out sounds around you if you’re playing music or a loud game, but you’ll still hear some ambient sounds if you have the volume low or your game doesn’t have a ton of audio.

SteelSeries promises that the charging case delivers 40 hours of battery life, with 10 hours for each use and three extra charges thanks to the case. I’ve found that the battery drains at around 10 percent an hour using the 2.4GHz connection, so the battery life looks like it will be solid. The case also offers wireless Qi charging (not Qi2) and a USB-C connection at the rear that will provide around three hours of play with 15 minutes of fast charging.
