Powered by the next-gen Bluetooth® 6.0 protocol, AirBuds 300 achieve lightning-fast 50 Mbps max data transfer, enhanced wireless stability over 15 meters, and 0.1s gaming audio latency. Thanks to the Hall sensor switch, the earbuds automatically reconnect to your paired device the moment you open the charging case.

Designed for active lifestyles, the earbuds feature IPX5 water and sweat resistance to withstand intense workouts and rain. The 500mAh charging case features an integrated smart LED digital power display, delivering up to 28 hours of total playback time with Type-C fast charging (10 minutes charge = 2 hours of talk time).
