Audio-Technica Consumer ATH-ANC20 QuietPoint Active Noise-Cancelling On-Ear Headphone Overview
The ATH-ANC20 QuietPoint Noise-Cancelling On-Ear Headphones block up to 80% of environmental noise and offer outstanding sound quality, comfort and portability. The headphones feature soft ear pads for long-wearing comfort. The detachable cord offers a convenient in-line volume control. Unlike many other noise-cancelling headphones, the ATH-ANC20 audio functions even without batteries or when its noise-cancelling function is turned off. The ATH-ANC20 folds for easy portability and storage and comes with an airline adapter, AAA battery and protective pouch.
Audio-Technica's QuietPoint headphones use active noise-cancelling technology to reduce distracting background noise, providing an exceptionally comfortable and restful listening environment in areas with high ambient noise. Active noise-cancelling headphones have components not present in ordinary headphones:
Microphone – Noise-cancelling headphones feature a miniature microphone in the earpiece that picks up ambient noise (such as traffic, air-handling systems, etc.)
Noise-canceling circuitry – Electronics in the ear piece create a noise-cancelling wave that is 180° out of phase with the ambient noise. This wave acts like a noise eraser: it cancels out the annoying sounds that surround you without diminishing the audio you want to hear. The result…a peaceful enclave to enjoy the music or movies of your choice.
Battery – The noise-cancelling electronics are battery-powered.
