Audio Technica ATH-ANC3 QuietPoint In-Ear Headphones - Black

What would life be like if you could press a Switch and arbitrarily cancel the noise around you? That's what the Audio Technica ATH-ANC3 QuietPoint In-Ear Headphones let you do.
Listening to Music through good earphones is really enjoyable. But ambient sounds (environmental noise) often conflicts with the pleasure and purity of what you're listening. Here's a headphone that makes hearing a pleasure.
Audio-Technica's ATH-ANC3 QuietPoint Active Noise-Cancelling In-Ear Headphones reduce distracting background noise by 85% while offering superior sound. 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. Electronics in the control box create a noise-cancelling wave that is 180-degrees out of phase with the ambient noise. While it acts like a noise eraser, the control box cancels out the annoying sounds that Surround you without diminishing the audio you want to hear. Sounds great, doesn't it?
