Blackview AirBuds 300 in Obsidian Black are open-ear wireless earbuds with ergonomic ear hooks that help keep them in place. Their open fit leaves the ears less enclosed than conventional in-ear designs, making it easier to remain aware of surrounding sounds. The hooks are made of TPE.
Bluetooth 6.0 connects to Android, iOS and HarmonyOS devices, as listed by Blackview. The 18.2 × 11.2 mm drivers have a stated frequency range of 20 Hz to 20 kHz. Dual ENC microphones are designed to reduce background noise during calls.
The 500 mAh charging case has a digital charge display and USB Type-C port. Blackview specifies up to 28 hours of total playback with the case and an IPX5 water-resistance rating. Touch controls manage playback, volume and calls.
