Has Active Noise Cancellation (Noise Control)

Skullcandy Indy Fuel ✗
ANC uses advanced technology to reduce unwanted ambient sounds. How it works, it listens to the sound pattern of incoming noise and then inverts the soundwaves to counter it. Simply put, it's like having +1 (sound from your surrounding) and adding -1 (counter sound by the device) giving zero which results in a reduced level of noise.
Bose QuietComfort Earbuds II have ANC allowing 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 sounds.
