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

Skullcandy Indy Fuel ✗
ANC uses advanced technology to reduce unwanted ambient sounds. ANC works when, it listens to the sound pattern outside and inside the earbud and inverts the soundwaves to cancel it out. In simple terms, it's like taking +1 (noise) then producing -1 (inverted noise) giving zero which results in a reduced level of noise.
JBL Live Free 2 have Active Noise Cancellation allowing you to listen at lower volume levels, causing less ear fatigue as you don't need to crank up the earbuds volume to overcome background noise.
