BESIGN Bone Conduction 2 in 1 Accessory 29g 250mAh 15h IPX5

Dual-mode bone conduction headset

This lightweight open-ear headset weighs 29g and uses bone conduction technology to transmit sound through vibration while keeping your ears uncovered. It defaults to hearing mode with a built-in HD microphone that picks up surrounding voices for conversations. The device automatically switches to Bluetooth audio when it detects sound or activity from a paired phone and returns to hearing mode after roughly three to five seconds of silence.

Suits users wanting awareness and audio

The open-ear design preserves situational awareness, making it useful for people who need to hear their environment while taking calls or listening to media. IPX5 rating protects against sweat and rain during outdoor use. Buyers who require full noise isolation or immersive bass response should consider a different style of headphone.

15-hour battery from 250mAh cell

A full charge of the integrated 250mAh lithium battery provides around 15 hours of use across both hearing and Bluetooth modes. Actual runtime will vary with volume level and the balance of time spent in each mode.
