I'm a veteran user of ear plugs in industry and hunting, and these are good plugs, but their shape makes them want to expand out of the ear more easily than other brands I've used in the past, so check them periodically. They do a great job of blocking sound (better than many others), and we will use all 200 pairs.
Pros: they block sound well, are comfortable
Cons: they fall out easy in a while due to shape
