Has Active Noise Cancellation (Noise Control)

Xiaomi Redmi Buds 4 Pro ✓
ANC utilises advanced technology to reduce unwanted ambient sounds. How it works, it studies the sound pattern of incoming noise and inverts the soundwaves to counter it. In simple terms, it's like having +1 (sound from your surrounding) and producing -1 (inverted noise) giving 0 thus "diluting" the noise.
The JBL Wave Buds have ANC enabling you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the earbuds volume to outcompete background sounds.
Xiaomi Redmi Buds 4 Pro too have ANC making both earbuds ideal for flights and morning commutes. The JBL Wave Buds and Xiaomi Redmi Buds 4 Pro operate with different noise cancellation modes, pick the setting that suits your commute or that suites your chill time.
