1. A non-occluding wearable audio device, comprising:
at least one electro-acoustic transducer;
at least one microphone; and
a control system coupled with the at least one electro-acoustic transducer and the at least one microphone, the control system programmed to:
adjust an active noise reduction (ANR) setting for audio output to the at least one electro-acoustic transducer in response to detecting use of the non-occluding wearable audio device in a vehicle, and
communicate with an audio control system in the vehicle, wherein the control system in the non-occluding wearable audio device and the audio control system in the vehicle are configured to coordinate audio output to reduce detectable noise by a user in the vehicle,
wherein, in a first frequency band, the audio control system in the vehicle is engaged to reduce the detectable noise, and
wherein the at least one microphone is configured to function as a feedforward microphone for applying ANR to an input signal at the non-occluding wearable audio device and as an error microphone for audio output by the audio control system in the vehicle.
