I bought it just for the case
These are apparently earplugs for when you only want to block some sound, but not too much, like going to a concert with too-loud music. And they are clear, so you can look cool while doing it.  I don't care about any of that, but I really like the case.  I bought this just for the case. I took the earplugs out and replaced them with the good 28 db NRR foam plugs.  I carry the case on my key ring, so I always have some hearing protection with me if I need it and don't have any muffs with me.  The case is nicely made from aluminum, and anodized.  The clip-on key ring looks sturdy and should remain intact.<br /><br />2018 UPDATE:  As I mentioned, I bought this just for the case.  I subsequently found out that these cases are readily available in most any drugstore.  They are sold as pill holders.
