1. An apparatus comprising:
- at least two earpieces suitable to be applied at auditory openings of a user'"'"'s ears, each of the earpieces comprising;
a speaker enabled to be supplied with an audio signal for rendering, anda microphone arranged in vicinity of the speaker arranged to acquire a sound signal; and
a signal processor, wherein the signal processor is arranged to determine whether the earpieces are applied at the user'"'"'s ears by analysis of the acquired sound signal,wherein the analysis is based on the acoustic coupling of the audio signal from a speaker of one of the earpieces to a microphone of one of the earpieces,wherein the acoustic coupling is between the speaker of one earpiece and the microphone of another earpiece.

Abstract
An apparatus comprising at least one earpiece suitable to be applied at an auditory opening of a user'"'"'s ear and a signal processor is disclosed. The earpiece comprises a speaker enabled to be supplied with an audio signal for rendering, and a microphone arranged in vicinity of the speaker arranged to acquire a sound signal. The signal processor is arranged to determine whether the earpiece is applied at the user'"'"'s ear by analysis of the acquired sound signal, wherein the analysis is based on the acoustic coupling of the audio signal to the microphone. A method and a computer program are also disclosed.

14. A method, for an apparatus comprising at least two earpieces suitable to be applied at a user'"'"'s ears for rendering an audio signal in the user'"'"'s ears when the earpieces are applied at the ears, each of the earpieces comprising a speaker enabled to be supplied with the audio signal for rendering and a microphone arranged in vicinity of the speaker, the method comprising
providing the audio signal to the speaker of one earpiece, acquiring a sound signal by the microphone of another earpiece; - and
determining by a signal processor whether one of the earpieces is applied at the user'"'"'s ear by analyzing the sound signal based on acoustic coupling of the audio signal from the speaker of the one earpiece to the microphone of the another earpiece. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A non-transitory computer readable medium comprising program code comprising instructions which when executed cause a method to be performed, the method comprising:
-
supplying an audio signal to a speaker of at least one earpiece suitable to be applied at a user'"'"'s ear for rendering the audio signal in the user'"'"'s ear when the earpiece is applied at the ear; acquiring a sound signal by a microphone of the earpiece arranged in vicinity of the speaker;
wherein the supplying of the audio signal is made to one earpiece and the acquiring is made at another earpiece, anddetermining whether the earpiece is applied at the user'"'"'s ear by analysis of the acquired sound signal based on acoustic coupling of the audio signal from the speaker of the one earpiece to the microphone of the another earpiece. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36)
