1. Earphones comprising:
a first earphone having a first sensor disposed around an audio output of the first earphone, the first sensor having a first biosignal electrode for collecting a first biosignal; and
a second earphone having a second sensor disposed around an audio output of the second earphone, the second sensor having a second biosignal electrode for collecting a second biosignal,
wherein the second earphone is wirelessly connected to the first earphone and configured to quantize the second biosignal into a second digital signal and transmit the second digital signal to the first earphone together with a set of marker bits representing a time at which the second biosignal is collected,
wherein the first earphone includes:
a biosignal processor configured to quantize the first biosignal into a first digital signal and synchronize the first and second digital signals with reference to the set of marker bits to generate an electrocardiogram (ECG) signal; and
a transmitter configured to transmit the ECG signal to a digital device wirelessly connected to the first earphone, and
wherein values of the set of marker bits are determined based on a bit-length of the set of marker bits and a number of sampling intervals between the time at which the second biosignal is collected and a predetermined reference time.
