Ultimate Ears Drops ✗
Active noise cancellation utilises advanced technology to actively counter noise. ANC works when, it studies the sound pattern outside and inside the earbud and inverts the soundwaves to counter it. Simply put, it's like having +1 (sound from your surrounding) then adding -1 (counter sound by the device) giving 0 therefore "diluting" the noise.
Jabra Evolve2 Buds have ANC enabling you to listen at lower levels of volume, good for your ears since you don't need to crank up the earbuds volume to overcome background noise.
