Has Active Noise Cancellation (Noise Control)

Bowers & Wilkins PI7 ✓
Active noise cancellation uses advanced technology to reduce ambient sounds. How it works, it listens to the sound pattern outside and inside the earbud and after inverts the soundwaves to counter it. In simple terms, it's like having +1 (sound from your surrounding) and adding -1 (counter sound by the device) to make zero resulting in a reduced level of noise.
Samsung Galaxy Buds 2 Pro have Active Noise Cancellation allowing you to listen at lower levels of volume, good for your ears as you don't have to crank up the earbuds volume to outcompete background noise.
The Bowers & Wilkins PI7 too have Active Noise Cancellation which makes either of the devices ideal for plane rides and rush hour commutes. Each operate with different noise cancellation settings, pick the noise cancellation type that suits your travel or that enhances your relaxation time.
