Various aspects include ported wearable audio devices. In certain implementations, a wearable audio device includes: a first cavity; a second cavity; a third cavity; a driver disposed between the first cavity and the second cavity, the driver configured to provide an acoustic output; a first mass and/or resistive port connecting the second cavity and the third cavity; and a second mass and/or resistive port connected to the third cavity.

Wearable audio device with tri-port acoustic cavity

Aspects of the present disclosure provide multi-layer microphone protection for any apparatus that captures sound. The apparatus includes an enclosure defining a first cavity. A microphone element is coupled to the first cavity. The microphone element comprises a microphone sensor and a microphone cavity. A first, outer protective layer is disposed at an outer end of the first cavity, closer to the external environment. A second, inner protective layer is disposed between an inner end of the first cavity and the microphone element. The second, inner protective layer may protect the microphone sensor from particles or liquids that may have passed through the first protective layer. The first and second layers may have different acoustic properties.
