ABSTRACT:
A mobile personal audio device including a case maintaining a power source, first and second speakers, a microcontroller, and first and second stem assemblies. The stem assemblies extend from opposite sides of the case, respectively, and each include a tube having a first end adjacent and open to a corresponding one of the speakers and terminating at a second end. The stem assemblies are configured such that the tube is positionable in a user-selected extended state in which the second end of the tube is displaced from the case, and a collapsed state in which the second end is in close proximity to the case. In the extended state, the case is locatable at the back of the user's neck, with the tubes extending along opposite sides of the user's head. The microcontroller operates the speakers to generate audio sounds waves that are delivered to the user's ears.
