ANC uses advanced kind of tech to reduce unwanted ambient sounds. ANC works when, it studies the sound pattern of incoming noise and after inverts the soundwaves to cancel it out. Simply put, it's like having +1 (sound from your surrounding) and adding -1 (inverted noise) to make 0 thus "diluting" the noise.
The Bose QuietComfort Earbuds 2 have Active Noise Cancellation allowing you to listen at lower volume levels, good for your ears since you don't need to crank up the device volume to outcompete background sounds.
The JBL Reflect Aero TWS too have ANC making either of the earbuds ideal for plane rides and rush hour commutes. The Bose QuietComfort Earbuds 2 and JBL Reflect Aero TWS work with different noise cancellation types, pick the mode that you prefer for travel or that suites your relaxation time.
