The USB base station of the Arctis Pro Wireless lacks the GameDAC of its wired sibling, so you’ll need to rely on your PC’s sound card for audio processing. Very clever, SteelSeries! The batteries are each rated for 10 hours of battery life. There's a second battery inside the wireless base station, which doubles as a battery charger, so you can swap batteries when needed. Pop off the cover of the right earcup and you’ll find the headset’s battery, which is easily removable. The mute button is cleverly designed it sticks out a bit more when the mic is muted so you can tell just from touch the status of your microphone. The volume dial is wide and rubbery, making it easy to find and adjust. The volume controls are located on the back of the left earcup. The result is the earcups felt a bit snug against my head, but at least they are covered in an extremely soft, breathable fabric that SteelSeries calls AirWeave. The band stretches a bit to create a comfortable, suspension-aided fit on your head, but its Velcro fastener lets you adjust the size only about one inch.
