The earplugs are large and suppress sound well. but loud bangs on the walls cannot be drowned out, of course. The mask is comfortable with two thin elastic bands, the size is adjustable
Not as expected as an iherb product ! The mask is rough and the ear plugs are not useful
Definitely less decibles than stated in box maybe 30 if not 28
