The ATH-ANC9 blocks up to 95% of outside noise - the highest ANC performance ever achieved by Audio-Technica QuietPoint headphones, while delivering superlative sound quality. Audio-Technica's new Tri-Level Cancellation provides three preset filters for noise reduction of up to 30 dB over a wide range of environmental noise conditions. Mode 1 is ideal for use on airplanes, trains and buses and applies maximum noise-cancellation to low frequencies. Mode 2 is designed for use in noisy offices and crowded places, and targets midrange frequencies. Mode 3 is best for already-quiet locations like libraries. The ATH-ANC9 features a cable with an inline microphone and controller for answering calls and controlling music. The mic and controller support select products including the iPhone, iPad and many iPod models. The microphone is designed for high-quality, intelligible response, enabling the wearer's voice to be clearly transmitted without having to speak directly into the mic. The controller enables the user to play or pause music, answer and end calls, and go to the next or previous track. The ATH-ANC9 has replaceable memory foam earpads for unmatched comfort, and is designed for exceptional audio quality. Its precision 40 mm drivers and newly developed electronics provide clear, natural full range sound. The headphones offer an input sensitivity of 100 dB that will provide an ample listening level from portable music sources. The ATH-ANC9 also works when the noise-cancelling function is turned off, and operates in passive mode without batteries. The headphones fold flat for storage and come with two detachable cables, a 1/4-inch adapter, an airline adapter, a hard carrying case and an AAA battery. The Audio-Technica ATH-ANC9 QuietPoint active noise-cancelling headphones are available now at a suggested retail price of US $349.95 at www.shopaudiotechnica.com and authorized retailers.
