ANC utilises advanced technology to actively counter noise. How it works, it detects and analyzes the sound pattern of incoming noise and inverts the soundwaves to cancel it out. In simple terms, it's like taking +1 (sound from your surrounding) and producing -1 (inverted noise) giving zero which results in a reduced level of noise.

Xiaomi Redmi Buds 4 Pro too have ANC which makes either of the devices ideal for plane rides and morning commutes. The OnePlus Buds Z2 and Xiaomi Redmi Buds 4 Pro work with different noise cancellation modes, pick the setting that suits your travel or that suites your chill time.
