With custom-made headwear:
1. The humanized microphone arm design allows the hose to be adjusted at any Angle, bending more tightly and comfortably.
2. Customized capacitive microphone core, clear sound pickup, effectively prevents howling.
3. The ear loops are made of silicone material, making them softer and more comfortable to wear.
