The product solves the traditional “trilemma” of balancing sound quality, comfort and noise cancellation, offering an optimal solution across all scenarios. It uses high-precision 3D ear canal scanning technology to customize an acoustic cavity for a snug fit. The exclusive electric air circulation system dynamically adjusts vent valves to promote air exchange between the inside and outside of the ear canal, addressing stuffiness and fullness. The product with the 6-axis IMU sensor enables head gesture-based control and health monitoring, achieving both intelligent interaction and heath care.
