ATH-ANC23 QuietPoint Active Noise-Cancelling In-Ear Headphones reduce
distracting background noise by up to 90% while offering the superior sound
that makes Audio-Technica a world-leading pro audio company.
Engineered to create a comfortable listening environment in areas with high
ambient noise, these in-ear headphones feature a miniature microphone in
each earpiece that picks up ambient noise (such as traffic, air-handling
systems, etc.). Electronics in the control box create a noise-cancelling
wave that is 180 degrees 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.
