1. A method of controlling an Active Noise Reduction (ANR) audio system, comprising:
detecting a first audio instability condition in a first headphone based on one or more ANR parameters of a first ANR state, wherein the first ANR state causes the first headphone to reduce noise in a first frequency range or depth, wherein the first audio instability condition is related to audio feedback; and
in response to detecting the first audio instability condition, altering a first ANR parameter of the one or more ANR parameters to change the first ANR state of the first headphone to a second ANR state, wherein the second ANR state causes the first headphone to reduce noise in a second frequency range or depth that is different than the first frequency range or depth; and
detecting a second audio instability condition in the first headphone based on the altered first ANR parameter of the one or more ANR parameters, wherein the second audio instability condition is related to audio feedback.
