Audio-Technica's ATH-ANC9 QuietPoint® headphones use proprietary noise cancellation technology. Comfortable sound enjoyment becomes possible in an environment with high ambient noise levels. Microphones are integrated into the earcups of these headphones, which pick up ambient noise (e.g. traffic, ventilation systems, etc.) and generate a signal with opposite polarity. This effectively blocks and suppresses ambient noise.

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