Abstract
A method and system directed to controlling Active Noise Reduction (ANR) audio devices with active noise reduction. The system sets one or more ANR parameters of a first and a second wearable audio device to a first ANR state; detects that the first wearable audio device is removed from a first ear of a user; and automatically adjusts the one or more ANR parameters of the second wearable audio device to a second ANR state when the first wearable audio device is removed from the ear of the user, wherein the second ANR state comprises a reduction in a level of ANR compared to the first ANR state.
