I’ve been using my wireless HyperX headphones for a while on Linux without any issue (just plug and play, insert the USB dongle and turn them on), but one thing has been bothering me: not knowing how much battery I have left. Normally on Windows you can check it via their Ngenuity app but it is not supported on Linux. Luckily someone already made a small tray application just for that. Note that this one only supports the Cloud Flight headset, but there is another one that supports the Cloud II Wireless and Cloud Stinger 2 headsets.
