The HUAWEI FreeBuds 6i feature enhanced algorithms and hardware for noise cancellation. The intelligent and dynamic ANC 3.0 identifies and calculates noise and wearing conditions in real-time, dynamically adjusting the level of noise cancellation for an optimal and personalized noise reduction effect. A C-shaped noise filter chamber, improved ear tips, three microphones, a 240% increase in processing power, a dynamic driver with four magnets, and five hardware upgrades for noise cancellation contribute to a better noise reduction effect. The 11 mm dynamic quad-magnet driver delivers dynamic bass performance.
