3. Wired Connection
If the headset battery is depleted or for devices without USB connectivity, you can use the included φ3.5mm wired connection cable.
- Connect one end of the φ3.5mm cable to the headset's 3.5mm audio jack.
- Connect the other end of the φ3.5mm cable to the audio output jack of your computer, display, or other compatible device.
- In wired mode, the headset's volume control, microphone mute, and speaker mute functions are not active. Adjust audio settings directly on your connected device.
4. Connecting to Smartphones (for Mixer Function)
To use the mixer function with a smartphone, connect your smartphone to the USB adapter's 3.5mm audio input using the included φ3.5mm wired connection cable. If your smartphone lacks a 3.5mm earphone jack, a separate audio conversion cable (e.g., Lightning to 3.5mm for iPhone, USB Type-C to 3.5mm for Android) is required and sold separately.

- Set the mode switch on the USB adapter to Mixer Mode.
- You will now hear both game audio from your console/PC and chat audio from your smartphone through the headset.
If you do not require the mixer function, you can switch the USB adapter to Game Mode.
