CARLYLE, JULIANNA - We released a fix for the issue that impacted the quality of sound from the speaker that resulted in audio sounding choppy or even skipping or rattling that gets worse over time.
If you're still having audio issues, check your watch to make sure you have the latest updates by going to Settings > System > About > System updates. Make sure you’re connected to Wi-fi for a faster download time. If you're still experiencing problems even with all the latest updates, it may be a hardware calibration issue. Try factory resetting your watch and setting it up again, doing this should realign calibration and solve the issue.
