Has Active Noise Cancellation (Noise Control)
JBL Live Pro 2

Bowers & Wilkins PI7 ✓
Active noise cancellation makes use of more advanced kind of tech to reduce unwanted ambient sounds. ANC works when, it listens to the sound pattern outside and inside the earbud and then inverts the soundwaves to cancel it out. Simply put, it's like having +1 (sound from your surrounding) then adding -1 (counter sound by the device) to make 0 therefore "diluting" the noise.
Bowers & Wilkins PI7 have Active Noise Cancellation allowing you to listen at lower levels of volume, causing less ear fatigue since you don't have to crank up the earbuds volume to outcompete background sounds.
JBL Live Pro 2 too have Active Noise Cancellation making both earbuds ideal for plane rides and morning travels. Each work with different noise cancellation types, pick the mode that suits your travel or that suites your chill time.
