Open-fit Active Noise Cancellation 2.0 on HUAWEI FreeBuds semi-in-ear earphones

Open-fit Active Noise Cancellation 2.0 uses advanced noise cancellation technologies with updated parameters for wind noise cancellation and self-adaptation, which effectively improves the low-frequency noise cancellation performance.

• Adaptive Ear Matching (AEM): This technology enables the earphones to automatically apply the optimal noise cancellation and audio quality parameters based on the ear canal structure and wearing status of each person, providing you with better noise cancellation and audio quality.
• AI sound effect: It is an application of the AEM technology in earphone sound effect processing. It provides sound quality compensation based on the ear canal type and characteristics of each person.
