Abstract
A convertible headphone system with headphones having a transducer with a front and a rear, and a back cavity that is fluidly coupled to the rear of the transducer, and an external acoustic structure that defines an acoustic volume. The headphones and the external acoustic structure are configured to be coupled together so as to fluidly couple the back cavity of the headphones to the acoustic volume of the external acoustic structure, to form an expanded back cavity volume.
