Operating the Headset
1. Adjusting Fit and Comfort
The Siberia 350 features a lightweight suspension headband designed for comfort during extended use. The earcups are circumaural, fully enclosing your ears. Adjust the headband for a snug yet comfortable fit. The earcups are designed to pivot slightly to conform to your head shape.

2. Microphone Usage
The headset includes a retractable microphone. To use the microphone, gently pull it out from the left earcup. Position the microphone approximately 1-2 inches from your mouth for optimal voice clarity. To mute the microphone, use the inline remote control or the SteelSeries Engine software. When not in use, the microphone can be pushed back into the earcup for storage.
3. Volume Control
Adjust the audio volume using the inline remote control located on the headset cable. Slide the wheel up or down to increase or decrease the volume. This remote also typically includes a microphone mute switch.
