1. Ergonomic design: By optimizing the head-mounted structure of the device, the weight is evenly distributed in different areas of the head, reducing the pressure on specific parts. In particular, the weight on the forehead and nose bridge is reduced, making it more comfortable to wear for a long time. 2. Balance center adjustment: The built-in balance adjustment mechanism reduces the front and back imbalance and relieves neck fatigue by reasonably configuring the hardware weight inside the headset. 3.Soft headband and padding: Using memory foam or other highly elastic materials as headbands and pads provides a softer touch and a tight fit, reducing the sense of oppression. 4. Adjustability: The tightness and angle of the headband can be flexibly adjusted according to the size and shape of the user's head to achieve a wearing experience.
