The audio apparatus can have a housing that contains the multiple microphones. The housing can be easily worn by a user, such as by coupling to a headset, ear mount/hook, user's clothing, or user's body. The microphones can be acoustically matched for rapid swapping without requiring a separate audio setup. The audio components can be mounted astride or near one another in the audio apparatus. The audio components can also be separately wired so that each audio component can be independently activated. ## Claims ### Claim 1 A wearable audio apparatus, comprising: a housing having an internal cavity;
