What is Active Noise Cancelling?
Active Noise Canceling (ANC) technology reduces unwanted low frequency background noises, allowing you to focus on your music, watch movies or make phone calls without distractions. The noise cancelling control function is assigned to your left earbud by default. Just simply press and hold your left earbud for 3 seconds to switch between Active Noise Cancellation (ANC), Transparency and OFF modes.
Please make sure your earbuds have ANC function first.
a) ANC mode - reduces external sounds. With this mode activated, you can enjoy music or phone calls without being disturbed by ambient noise.
b) Transparency mode - lets external sounds in, so you can hear what's going on around you.
c) OFF mode turns off both ANC and Transparency modes.
