As far as I am Aware they do not need to be changed fought out of the box but you do need to change them from time to time when the batteries get low.
Sorry, there was a problem. Please try again later.I charged mine first. They do not come fully charged right out of the package. You could probably go ahead and use them if you are using them connected to the device since you have to connect to charge and sync them anyways. They did not take long to charge though.
