  • Patent number: 9277310
    Abstract: An audio playback system for an audio signal generated by an audio output device includes a generally U-shaped headphone arrangement having two opposing ends each terminating with an audio transducer. A top enclosure of the headphone arrangement includes a remote control holder, a personal attachment holder, and a headphone circuit. A remote control is adapted for selective engagement with the remote control holder of the headphone arrangement and is fixable to a personal attachment and worn by the user. Control signals are transmitted to the headphone arrangement by the remote control in response to the person interacting with the remote control. The headphone circuit alters the audio output of the headphone circuit in accordance thereto. The headphone circuit receives the audio signal directly from the audio output device, the network, or indirectly from the remote control. The remote control is also adapted for controlling the audio output device and network.
