Compared with Intelligent dynamic ANC 2.0, Intelligent dynamic ANC 3.0 generates noise cancellation parameters through real-time model building, with the algorithm specially trained and tuned for 34 scenarios. HUAWEI FreeBuds 6i monitors noise every 2.6 μs and adjusts the parameters within about a second to seamlessly optimize noise cancellation for your surroundings.

1. Noise Filtering Chamber

Noises passing through the earbuds are absorbed into and attenuated in the noise filtering chamber, with background chatter in the medium- and high-frequency range reduced the most.

2. 3-Mic System

Each earbud packs three microphones, which feature a 50% higher signal-to-noise ratio (SNR) than the previous generation, and boost the earbuds' performance in cancelling out medium- and low-frequency noises.

3. 2.4 × Higher Computing Power

HUAWEI FreeBuds 6i features 240% higher computing power than the previous generation thanks to Intelligent Dynamic ANC 3.0, which allows it to calculate the inverted-phase sound waves of in-ear noise in real time and send instructions to the driver unit.

4. 11 mm Quad-magnet Dynamic Driver

The 11 mm quad-magnet dynamic drivers are 50% more sensitive than the previous generation, and generate reverse sound waves to counteract the noise entering your ears.

5. Enhanced Ear Tips

Ear tips made of skin-friendly liquid silicone provide a silky smooth touch, and come in three sizes. They provide a more secure fit and enhanced noise cancellation performance with superior airtightness. Select a pair of ear tips that best fit your ears.

You can listen for 8 hours(ANC off) when using the earbuds alone on a single charge, and listen for an astounding 35 hours(ANC off) with a fully charged case, HUAWEI FreeBuds 6i support up to 4 hours of listening after just 10 minutes of charging, to get going and grooving without missing a beat.

Yes! HUAWEI FreeBuds 6i equipped with three microphones that work in tandem with deep neural network (DNN) algorithm to distinguish voices from noise and cancel out noise during calls.

Yes, HUAWEI FreeBuds 6i earphones come with IP54 dust- and water-resistance.(The charging case is not IP54)
