The G935 gaming headset has two operation modes, Wireless On, and Wireless Off.
These modes affect the operational capabilities of the G935 when connected to different compatible devices.

WIRELESS ON
In Wireless On mode, most headset features on the G935 gaming headset are available, including custom sound profiles, RGB lighting, wireless operation, and audio mixing.
When the battery charge is low, lighting will dim and a low battery notification tone will play. When the battery charge level on the headset is critical, lighting will turn off.

NOTE: Some features in Wireless On mode require Logitech G HUB Software.


WIRELESS OFF (PASSIVE)
In Wireless Off (passive mode), the G935 gaming headset will operate in passive, unpowered mode.
Your headset will play audio from any device connected through the 3.5mm input on the headset.
Features that require power, including 7.1 surround sound, custom sound profiles, on-headset buttons, volume wheel operation, and button/lighting customization functions are not available in this mode.

NOTE: You can use Wireless Off mode to preserve battery life.
