JBL LIVE 300 ✗
ANC uses more advanced technology to actively counter noise. ANC works when, it listens to the sound pattern outside and inside the earbud and after generates a mirror signal to cancel it out. In simple terms, it's like taking +1 (sound from your surrounding) then producing -1 (counter sound by the device) giving 0 hence "diluting" the noise.
The Jabra Elite 7 Pro have Active Noise Cancellation enabling you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the earbuds volume to overcome background noise.
