Abstract
A method and system directed to controlling Active Noise Reduction (ANR) audio devices with active noise reduction. The system generates one or more control signals, using a controller, to set one or more ANR parameters of a first and a second wearable audio device to a first ANR state; detects at least one of: whether the first wearable audio device is engaged with or removed from a first ear of a user, using a first sensor of the first wearable audio device; or whether a second wearable audio device is engaged with or removed form a second ear of a user, using a second sensor of the second wearable audio device; and automatically adjusts the one or more ANR parameters of the first and/or second wearable audio device to a second ANR state when either the first wearable audio device or the second wearable audio device, or both, are removed from an ear of the user, wherein the second ANR state comprises a reduction in a level of ANR at least at some frequencies compared to the first ANR state.
