Active noise cancellation uses advanced kind of tech to actively counter noise. ANC works when, it listens to the sound pattern of incoming noise and generates a mirror signal to counter it. In simple terms, it's like having +1 (noise) and producing -1 (counter sound by the device) giving zero hence "diluting" the noise.
The Xiaomi FlipBuds Pro have ANC enabling you to listen at lower levels of volume, good for your ears since you don't need to crank up the device volume to overcome background sounds.
The Sony WF 1000XM4 too have Active Noise Cancellation making both earbuds ideal for flights and morning travels. The Xiaomi FlipBuds Pro and Sony WF 1000XM4 work with different noise cancellation types, pick the setting that suits your travel or that suites your chill time.
