A blood pressure measurement method, intelligent heart rate monitor earphone (1), and system. Each earbud of the intelligent heart rate monitor earphone (1) is integrated with at least one heart rate monitor chip, and the intelligent hear rate monitor earphone (1) communicates with an intelligent portable terminal (2). The method comprises: acquiring, by means of the intelligent heart rate monitor earphone (1), a photoplethysmographic pulse wave (101) of an ear of a user and a photoplethysmographic pulse wave (102) of another portion of the user; transmitting, in a real-time and synchronized manner, to a processor the photoplethysmographic pulse wave (101) of the ear of the user and the photoplethysmographic pulse wave (102) of the other portion of the user; and processing, by means of the processor, the photoplethysmographic pulse wave (101) of the ear of the user and the photoplethysmographic pulse wave (102) of the other portion of the user to obtain a blood pressure value of the user.
