Upgrade the expandable headband structure and say goodbye to the constraints of fixed sizes! The elasticity can be adjusted as desired, whether it is small head circumference, large head circumference, or long hair or short hair, it can be accurately matched. Ergonomic design that conforms to the curve of the head, with even force distribution without pressing or gripping the ears. The lightweight body has no weight-bearing sensation, and can be worn for long live broadcasts, entire performances, and all day teaching, still comfortable and comfortable without discomfort.
Running, turning the head, and large movements are also stable and do not slip off, with zero pressure when worn.
