The new ATH-ANC3 Quietpoint headphones are smaller and promise to deliver exceptionally pure audio signal and an active noise cancelling function that cancels 85 percent of background noise at a very attractive price. ANC3 has a small in-line control box that comes with an on/off switch and Monitor button that mutes all functions (including the noise-cancelling function) when the unit is turned on in order to listen to announcements or important conversations.
