Huawei FreeBuds 6i In-Ear Headphones, True Wireless, Hybrid ANC, Bluetooth, Purple Intelligent dynamic ANC 3.0 Intelligent dynamic ANC 3.0 generates noise cancellation parameters by building a real-time model, with the algorithm specially trained and tuned for 34 scenarios. HUAWEI FreeBuds 6i monitors noise every 2.6 μs and adjusts parameters in about a second2 to seamlessly optimize noise cancellation for the environment. Less noise, more concentration HUAWEI FreeBuds 6i is designed to cope with everyday scenarios, such as subway rides, which involve disturbing noise levels across a wide range of frequencies, such as rolling wheels, conversations, and door opening/closing. Simply put on your headphones, turn on ANC, and tune into your favorite tunes. Noise Filtering Chamber Noise passing through the earphones is absorbed and attenuated in the noise filtering chamber, and background noise in the mid- and high-frequency range is most reduced. 3-Mic System Each earbud contains three microphones, which have a 50% higher signal-to-noise ratio (SNR) than the previous generation5 and enhance the earphones' performance in canceling mid- and low-frequency noise. 2.4× Higher Computing Power HUAWEI FreeBuds 6i has 240% higher computing power than the previous generation6 thanks to the Intelligent Dynamic ANC 3.0 system, which allows it to calculate the inverse-phase sound waves of the noise inside the ear in real time and send instructions to the driver unit. 11mm Quad-Magnet Dynamic DriverThe 11mm quad-magnet dynamic drivers are 50% more sensitive than the previous generation and generate reverse sound waves to counteract noise entering your ears. Improved ear capsThe ear tips made of skin-friendly liquid silicone offer a smooth and silky touch and are available in three sizes. They offer a more secure fit and improved noise-cancelling performance with a superior seal. Select a pair of ear tips that best fits your ears. Distraction-free callingThe headphones are equipped with three microphones that work in tandem with the Deep Neural Network (DNN) algorithm to distinguish voices from noise and cancel out noise during calls. Powerful BassThe 11mm quad-magnet dynamic drivers are 50% more powerful and Hi-Res certified, producing powerful bass down to 14Hz that will surely take your breath away. Easy on the EyesThe HUAWEI FreeBuds 6i features a sleek design with three stylish colors, each offering a unique charm. Easy on the EarsThanks to simulations conducted on more than 10,000 ear samples, the in-ear components are 6% smaller, and key indicators that directly affect wearing comfort have been optimized. The skin-friendly ear tips made of liquid silicone enhance noise cancellation performance without compromising wearing comfort.
