The Bluetooth connection on the Arctis Nova 7X and Nova 7X Gen 2 works independently from the power button. That means even when you power off your headset, Bluetooth can stay active if it was previously turned on.
This design lets you keep your Bluetooth connection (like a phone call or chat) going while your wireless mode is off — but it can also catch players by surprise if they expect the light to turn off completely.
To fully power down Bluetooth, simply press the Bluetooth button on the headset, just like you would press the power button to turn the headset off. Once it’s off, the headset will no longer appear as a Bluetooth device on your connected devices list.
