Audio-Technica ATH-ANC9 QuietPoint Active Noise-Cancelling Headphones

The Audio-Technica ATH-ANC9 QuietPoint® on-ear headphones use proprietary active noise-cancelling technology to provide a comfortable listening environment in areas with high ambient noise. Delivering noise cancellation up to a remarkable 95%, the ATH-ANC9 QuietPoint® headphones feature Audio-Technica’s new Tri-Level Cancellation™. Mode 1, ideal for use on aeroplanes, trains and buses, applies maximum noise cancellation to low frequencies. Mode 2, designed especially for use in noisy offices or crowded places, targets the mid-range frequencies, while Mode 3 creates a pristine, peaceful environment ideal for study.

The headphones feature four miniature microphones, two in each earpiece, that pick up ambient noise and create a sound-cancelling signal to effectively block the noise. The ATH-ANC9 headphones also offer a cable with an inline microphone and controller for answering calls and controlling music. The mic and controller support select products, including iPhones, iPads, and many iPods. The microphone has an omnidirectional pickup pattern and it is designed for crisp intelligibility, so your voice will be clearly transmitted without having to speak directly into the mic.

These headphones are designed to offer you crystal-clear sound that makes Audio-Technica the choice of leading artists worldwide. Wherever you happen to find yourself — in the comfort of your living room, in a noisy office or settling in for a long flight — there is no better way to experience audio or immerse yourself in a peaceful environment.

The Audio-Technica ATH-ANC9 feature active, battery-powered noise cancellation. Audio can be played back in both active or passive mode and does not require battery power. The headphones have three modes of active noise cancellation:

• Mode 1: Ideal for use on aeroplanes, trains and buses and applies maximum noise cancellation to low frequencies
• Mode 2: Designed especially for use in noisy offices or crowded places and targets the mid-range frequencies
• Mode 3: Creates an environment ideal for study

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.

Passive noise-reduction
Passive noise-reducing headphones and earphones do not offer active noise-cancelling electronics. Instead, closed-back sealed headphones achieve passive noise-reduction by physically covering the ears to help block out external noises.

Passive noise-reducing earphones offer an in-ear design that forms an acoustic seal that helps to block background noise and allow for increased fidelity at lower volume levels.
