Sound Quality

Has Active Noise Cancellation (Noise Control)

Bowers & Wilkins PI7
Sennheiser Momentum True Wireless 3

Active noise cancellation makes use of advanced kind of tech to reduce ambient sounds. ANC works when, it listens to the sound pattern of incoming noise and generates a mirror signal to cancel it out. Simply put, it's like having +1 (sound from your surrounding) and producing -1 (counter sound by the device) to make zero resulting in a reduced level of noise.

The Bowers & Wilkins PI7 have Active Noise Cancellation enabling you to listen at lower levels of volume, good for your ears since you don't have to crank up the device volume to overcome background sounds.

The Sennheiser Momentum True Wireless 3 too have Active Noise Cancellation making either of the earbuds ideal for flights and morning commutes. The Bowers & Wilkins PI7 and Sennheiser Momentum True Wireless 3 work with different noise cancellation settings, pick the noise cancellation type that suits your travel or that enhances your chill time.
