A method for generating a 3D audio representation of an audio by a first wireless headphone: collecting a first audio signal; generating a first counting signal; generating a first synchronizing signal based on the first counting signal; and retrieving a portion of the first audio signal. The method includes, by a second wireless headphone: receiving a wireless signal from the first wireless headphone, indicating a first local clock of the first wireless headphone; synchronizing a second local clock of the second wireless headphone with the first local clock; collecting a second audio signal; generating a second synchronizing signal based on the second local clock; and retrieving a portion of the second audio signal. The method further includes generating, by a user equipment, the 3D audio representation of the audio based on the first and the second audio signals and the first and the second synchronizing signals.
