Audio-Technica's ATH-ANC9 QuietPoint headphones use proprietary noise cancellation technology, allowing for comfortable sound enjoyment in environments with high ambient noise levels. Microphones integrated into the earcups pick up ambient noise (e.g., traffic, ventilation systems) and generate a signal with opposite polarity, effectively blocking and suppressing that noise.

Tri-Level noise suppression
The ATH-ANC9 QuietPoint headphones feature Tri-Level noise cancellation with three unique setting modes for effective noise reduction in various environments.

Mode 1: Ideal for use in aircraft, trains, and buses, offering maximum noise reduction in the low frequency range.
Mode 2: Specially designed for noisy offices and busy public places, focusing on noise suppression in the medium frequency range.
Mode 3: Suitable for quiet environments, such as libraries, creating a pure and relaxing atmosphere ideal for learning and study situations.

Integrated controller
The ATH-ANC9 QuietPoint headphones are the first noise-canceling model to include a cable with a built-in microphone, extending functionality to accept and make phone calls and control music files directly via the controller. The microphone and controller support selected smartphones and touchpads, and its omnidirectional nature allows you to hear your voice clearly without needing to speak directly into it.

Leading sound
These headphones are designed to provide a crystal-clear sound experience, making Audio-Technica the first choice for artists and musicians worldwide. Audio-Technica products are used by leading artists in studio, recording, and live performance markets, ensuring that fans and listeners experience the wide range and depth of sound as intended by the artists.
