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

A headset cup having a front cavity and a rear cavity separated by a driver, with a mass port tube connected to the rear port to present a reactive acoustic impedance to the rear cavity, in parallel with a resistive port, the total acoustic response of the rear cavity remaining linear at high power levels. In some embodiments, the mass port tube is made of metal, while the headset cup is otherwise made of plastic.

Headset porting

A power supply includes a battery source supplying power and a voltage converter circuit. The voltage converter circuit converts the power to the input voltage supplied to other circuitry. The voltage converter circuit varies the input voltage in response to a load current drawn by the other circuitry from the power supply.
