How to use

Charge the built‑in lithium‑ion battery via the USB‑C port before first use. Turn on the headset and pair it with a device through Bluetooth 5.3 or connect directly using a USB‑C cable when available. Position the head‑band so the circumaural ear cups fully enclose the ears for best comfort and passive isolation. Use the boom microphone for voice chat, adjusting orientation as needed for clear pickup. Follow manufacturer instructions for power, pairing, and firmware updates.

Recommendations

For optimal microphone clarity, position the boom mic near the corner of your mouth and keep it a short distance away to avoid plosive sounds. Charge the headset before long sessions and use the USB‑C connection when uninterrupted, low‑latency audio is required.
