Setting synchronization method, TWS earphone and equipment system

The invention discloses a setting synchronization method, a TWS earphone and an equipment system, and relates to the technical field of terminals. The method comprises the following steps: when an update parameter of a first earphone is a first parameter value and a timestamp parameter of the first earphone is smaller than a timestamp parameter of a second earphone, performing set synchronization according to synchronization information sent by the second earphone; or, when the update parameter of the first earphone is a second parameter value, the first earphone performs set synchronization according to the synchronization information sent by the second earphone; the first parameter value represents that setting is updated when the earphone itself is used as a main earphone, and the second parameter value represents that the earphone itself is not used as the main earphone for setting synchronization; the timestamp parameter is the time when the earphone obtains update information sent by the electronic equi
