In general, because of this desynchronization, it is impossible to watch the video. Moreover, this problem is UNSOLVED on non-Samsung devices, i. E. ating and rolling back firmware, changing bluetooth receivers (their versions) on a PC, smartphones WILL NOT HELP. Of course, the official support of Samsung has never admitted that there is such a problem. But as soon as I called one of the authorized Samsung service centers, the nice girl immediately said, "Oh, well, this is their disease and it cannot be treated." I am surprised how many thousands of users of these headphones are silent about this problem.
