Claim 9:
10. A method for synchronized media playback, the method comprising:
determining that a media device in a media group has been selected as a leader device, wherein a remaining media device in the media group has been designated as a follower device from the media group;
receiving, from the follower device, synchronization requests, wherein
the synchronization requests are transmitted at a first rate prior to causing a media stream to be played back on the follower device and transmitted at a second rate that is greater than the first rate while the media stream is being played back on the follower device;

transmitting synchronization responses that are responsive to the synchronization requests to the follower device, wherein a clock offset between the leader device and the follower device is based on the synchronization requests and the synchronization responses; and
causing the media stream to be played back on the follower device in synchronization with the leader device based on the clock offset.
