Environmental Noise Cancellation in short ENC works similar to Adaptive Qualcomm’s Noise Cancellation technology. Often there are 3-built-in mic on each earbud to do the job. The earbuds will automatically adjust the noise cancelling performance according the environment it senses – one mic must continuously pick out the sound and delivere to the SoC (system on chip) in form of electric signal. This in turns can enhance the sound that users want to hear such as notification voice at the airport and cancel out the intense, harsh sound.
