BE Live2 uses an aluminum alloy as its base material. A vacuum evaporation technique imparts a mirror-like, high-gloss stainless steel surface texture. This is further complemented by a sleek, fluid contour that reflects ambient light for exquisitely tasteful visual aesthetics and a tantalizingly smooth texture. The BE Live2 supports AAC high-quality sound resolution, wirelessly delivering the same level of audio quality as a CD and satisfying your desire for both aesthetics and a quality sound experience. The 10-hour high battery life enables you to enjoy music throughout the day. The built-in microphone enables you to make phone calls and issue commands to your voice assistant. Meets IPX5 water resistance standards and is good for wet weather, travel or sports where you do not have to worry about the rain or sweat damaging your headset.
