There's tons of mask varieties such as the "festival" type that are scarf coverings of the nose and mouth, obviously not medical grade but meet the basic requirement for grocery shopping and whatnot.

This is an example from amazon, though there are plenty.
Also, I find the cotton ones relieve my stress over my mouth being covered, but I doubt that helps with the ears.
Finally, if you're willing to put in the extra money there are some extremely comfortable options (the filters make it feel very easy to breath and the ear straps are very comfortable).

This is another example from amazon, but obviously there are a variety of options for this as well.
Hope this helps :)
