Etymotic Research ER20XS High Fidelity Reusable Earplugs - Low Profile Fit and Waterproof Case - Noise Reduction Ear Plugs for Concerts, Musicians, Raves, Sporting Events & Festivals - Universal Fit

As a pro musician, I'm using these for gigs as well as shows I'm just attending. For the low price of these I didn't expect a huge difference in clarity but was pleasantly surprised.

Not a lot to like here. Two sizes of ear buds, large and small. They need a medium too. The pocket case is enourmous - you could fit ear plugs for an elephant in that thing! Biggest problem is I can't tell a difference between these at $25 and the regular silicone ones that go for 20 cents. I wanted to like these, but they're going back.

I added photos to show whats included in the universal set with waterproof container. 2 foot neck cord.I don't usually have problems with earplugs but I did with these. The smaller size set up reaches all the way to my eardrums and don't seal well. I have normal size ear canals and can use similar style earplugs with medium size. It appears these come with small and a large.Haven't tested the sound quality through them on yet.

Got these to use at thrash metal shows, barely protected my ears. If you want the minimum protection then these may be for you! Side note, I have small ears and these hurt like hell. Think I’ll just stick to disposable foam plugs for now.

The case is absurdly large, and even the smallest plugs hurt to put in my ears and are uncomfortable to wear.
