1. A method for performing audio enhancement with aid of timing control, the method being applied to a user equipment (UE) wirelessly connected to a first earphone and a second earphone, the method comprising:
utilizing the UE to determine a first predetermined synchronization delay and notify the first earphone of the first predetermined synchronization delay, wherein a first digital signal processing (DSP) circuit in the first earphone is arranged to determine a synchronization point according to a first time point of a first event and the first predetermined synchronization delay for the first earphone;
utilizing the UE to determine a second predetermined synchronization delay and notify the second earphone of the second predetermined synchronization delay, wherein a second DSP circuit in the second earphone is arranged to determine the synchronization point according to a second time point of a second event and the second predetermined synchronization delay for the second earphone; and
utilizing the UE to receive first uplink audio data from the first earphone and receive second uplink audio data from the second earphone, wherein the first DSP circuit and the second DSP circuit are arranged to control timing of the first uplink audio data from the first earphone to the UE and timing of the second uplink audio data from the second earphone to the UE according to a first reference point for the first earphone and the second earphone, respectively, wherein the first reference point is determined at least according to the synchronization point.
