My buds work intermittently. Sometimes they work but if I pause a video, or adjust the volume, the video will slow down so much you xan barely see a person moving. Other times, the video will be like this from the beginning. I have a Samsung A52 which was new with the buds about 6 weeks ago. The buds seemed fine to start off with, I've updated the phone software and no improvement. They seemed to work OK the first couple of uses but that could have been luck! The buds are making sound as I can hear the background noise.
