Classification: CPC H | IPC H

Claim 11:
12. The wearable audio output device of claim 9, wherein:
in order to compare the measured driver to first microphone transfer function associated with the audio signal and the expected driver to first microphone transfer function for the audio signal in the frequency range the memory further includes instructions executable by the at least one processor to cause the wearable audio output device to determine the measured driver to first microphone transfer function is less than the expected driver to first microphone transfer function by a threshold amount in the frequency range;
in order to determine the wearable audio output device is one of in the ear of the user or out of the ear of the user, the memory further includes instructions executable by the at least one processor to cause the wearable audio output device to determine the wearable audio output device is in the ear of the user; and
in order to predict the nozzle is at least partially blocked based, at least in part, on the comparison, the memory further includes instructions executable by the at least one processor to cause the wearable audio output device to predict the nozzle is at least partially blocked based on the comparing and determination the wearable audio output device is in the ear of the user.
