Question about ASUS ROG Strix Wireless

For charging there is a normal mini USB cable, a docking station is not available.

Exactly, standard mini USB for charging. In addition, you can connect the headset via jack and then do not need to switch it on to use it. This may be practical when the battery is empty. But actually you buy a wireless headset to play without a cable. It's a pity when the manufacturer forgets to develop the appropriate drivers and still writes "MacOS compatible" on the package.
