Abstract
A circumaural headset having a first earcup and a second earcup can include a first transducer disposed with the first earcup and configured to transmit a first non-audible signal with an audible signal, a second transducer disposed within the second earcup and configured to receive the first non-audible signal from the first transducer, and an off-ear detection processor configured to determine whether the headset has been removed from the user's head based on the second transducer receiving the first non-audible signal from the first transducer.
