1. A method of synchronizing an earbud and a sensor housed in the earbud, comprising:
receiving, at a first time, by one or more processors, a first plurality of timestamps, the first plurality of timestamps including a first source timestamp from the sensor and a first target timestamp from the target clock of the earbud;
determining, by the one or more processors, a first synchronization factor based on a comparison between the first source timestamp and the first target timestamp;
receiving at a second time, by one or more processors, a second plurality of timestamps, the second plurality of second timestamps including a second source timestamp from the sensor and a second target timestamp from the target clock; and
synchronizing, by the one or more processors, the second source timestamp to a time base of the target clock based on the first synchronization factor.
