Pair two devices when needed to receive calls from either device without disconnecting. Use the companion app or OTA updates to enable Audio Mode or Video Mode when available.

Recommendations

For best performance, keep firmware up to date via OTA updates, use ANC for noisy environments, and Smart Ambient when you need to hear announcements or have short conversations without removing the headset.
