The built-in microphone utilizes an environmental noise-cancelling algorithm to reduce background noise during calls, ensuring clearer communication.

For an optimized experience during gaming or video playback, the earphones feature a low latency mode. This mode reduces audio delay, ensuring better synchronization between audio and video. This feature is automatically enabled when connected to compatible OnePlus devices.
Maintenance
Proper maintenance ensures the longevity and optimal performance of your earphones.
- Cleaning: Regularly clean the earbuds and ear tips with a soft, dry, lint-free cloth. Remove ear tips and clean any earwax or debris from the speaker mesh using a small, soft brush. Do not use harsh chemicals or abrasive materials.
- Storage: When not in use, store the earphones in a clean, dry place away from extreme temperatures and direct sunlight. Use the magnetic control to power them off to save battery.
- Water Exposure: While IP55 rated, avoid prolonged exposure to water. If they get wet, wipe them dry thoroughly before charging or storing.
