Audio-Technica ATHANC7 Noise-cancelling Headphones

Audio-Technica's lightweight and compact ATH-ANC7 QuietPoint headphones are ideal for use with MP3, CD, DVD and in-flight entertainment systems; with fully integrated ANC circuitry that effectively reduces distracting background noise by up to 85% (active noise reduction up to 20dB). 40mm drivers with neodymium magnet systems in each earpiece provide superior audio quality for deeper bass, extended treble and higher fidelity; while a single AAA battery powers the active noise-cancelling technology with or without audio. ATH-ANC7 QuietPoint headphones fold flat for easy portability and include a detachable cable (remove for noise-cancelling function without audio) with 3.5mm mini-plugs, a full-size ¼" adapter, a specialized airline adapter for connecting to in-flight entertainment systems, and a handy carrying case. The detachable cable is 5.2 inches long.
