Hello @Su_medley.
I cannot tell you how many times I have dropped the Wyze Buds Pro case in various locations (and some not so dry places) and they have exploded out of the case… not in any instance of my slippery hands did the performance deteriorate with a drop, but, this has been my experience.
While dropping them on a padded floor seems to be much gentler than what my Pro Buds have been through, they are still an electronic device and could be impacted by any type of drop.
Check to see if you don’t have some debris in the bud that might have come loose in the drop and it’s blocking the speaker.
There is no balance setting within the Wyze App.
Check to see if they are clean, and if not give them a what for again, maybe a jolt will straighten them out?
