Reduces pressure on the ears. ● Equipped with noise-canceling and a high-sensitivity microphone, suppressing noise during calls and surrounding noise, making it easier to hear the other person's voice and enabling comfortable calls. ● It doesn't feel heavy when worn, and the ergonomic in-ear curved surface and angle fit the shape of the ear canal. The charger uses a frosted sand material, which is gentle on the skin and provides a comfortable feel. It fits so well that you'll forget you're wearing it. When powered on, you'll hear a Chinese or Korean announcement for login, but I don't mind it at all.
