ONEPLUS BT31B Bluetooth Sports Earphone

At the launch of OnePlus 6, OnePlus also introduced a Bluetooth headset “BT31B”, which is also the first Bluetooth headset from OnePlus.

The exterior of the OnePlus BT31B features a unique streamlined “horn” design that symbolizes the power of sound. The personality is vivid and dynamic; the contour of the surface is from inside to outside, which is very fluid; the chamfering surface of the CD pattern process is more flexible. Titanium alloy skeleton + liquid silicone surface, make the lanyard tough and durable, and affect the skin; the body is light and comfortable to wear.

Magnetic adsorption has a switching function, which is convenient for anti-lost and energy saving. ONEPLUS BT31B supports OnePlus Dash flash charging, 8 hours long battery life at full power, and 10 hours of continuous listening for 5 hours. The ONEPLUS BT31B also supports automatic voice announcement and automatic answering. Life waterproof design makes outdoor sports more assured.

The two in-ear earphones are connected by a cable, so they are not completely wireless. When the two earphones are not in use, they can be attracted together by the magnet, and they will automatically close when they are closed to save power.

The headset supports aptX high-quality audio and is equipped with an Energy Tubes 9.2 mm drive unit that directs sound to the eardrum. The earphones are made of non-metallic minerals and silicone, and the addition of headphones adds a clearer and richer sound.
