Bone-stream earphone sets are not unusual products, but they are less popular because they do not provide quite as robust audio quality as more traditional audio accessories. In Malaysia, one of the brands that offers audio accessories like this is Aftershokz.
In addition to not being very popular, the selling price of such products is often high. Xiaomi in China seems to want to try to offer a product in this category at a price that can be said to be quite affordable compared to other brands through the Xiaomi Bone Conduction Headphones.
Xiaomi Bone Conduction Headphones use technology that emits audio through vibration where when close to the cheekbones, the wearer can continue to hear the audio produced. This set of earphones is also made so that the wearer can always be aware of what is going on around them, meaning that there is no ANC support or sound-through mode included.
Xiaomi uses a track-type vibration system that claims the audio quality is better and can also ensure that there is no audio leakage problem with the 360 degree closed directional sound cavity technology. Xiaomi Bone Conduction Headphones use Bluetooth 5.2 with fast tethering, time gap as low as 86ms, battery up to 12 hours, USB-C charging, and comes with IP66 protection.
The selling price is RMB699, which is around RM456 and is limited to the Chinese market only for now.
