Imagine arriving refreshed after a long flight, shutting out unwanted distractions in a noisy office and the luxury of finding peace and quiet on your commute home. Audio-Technica's newly designed ANC7b QuietPoint closed-back headphones are the successor of the award-winning ANC7 headphones and are designed for use with MP3, CD, DVD and in-flight entertainment systems, as well as all Apple™ products.
They feature large aperture 40mm drivers with neodymium magnet systems, giving you deeper bass, extended treble and high fidelity. Noise-cancelling electronics are fully integrated in each comfortable earpiece with no need for external modules and the headphones effectively cancel background noise by up to 85%. One AAA battery powers the active noise-cancelling technology and the audio functions in passive mode even without the battery.
The ANC7b QuietPoint headphones fold flat and are easily portable, in a lightweight, compact design that's easy to carry for pure shut the world out bliss.
