They're long-lasting and usable. The case is built like a tank.
Disclaimer, I have bought no other musician's earplugs, so I don't have a point of comparison for my "sound quality/noise cancellation/value" ratings. I just think these earplugs work well enough for my situation, and considering that it's probably the cheapest option on Amazon, I would recommend it.<br /><br />I work at a restaurant and use these every day to protect my hearing from clanking plates, metal pans and breaking glass.<br /><br />Clarity of sound is not perfect, higher end gets muted or even nearly unnoticable. With these on, I can't hear my car's right/left blinker unless I really concentrate. But the high end muting has its advantages, like for example, the loudest thing at my workplace by far is a recycle bin full of ~20lbs glass, being emptied into a chest-height container. The glass breaking noise is all high end. So these earplugs are perfect for me!<br /><br />If you're using this for playing music, a word to violinists, a lot of sound travels from the chinrest of the violin through your jaw, completely bypassing these earplugs. So if you're in an orchestra playing violin like I was, the sounds of your own playing will drown out every other sound, making playing in the ensemble more difficult. Literally an unsolvable problem though, not a problem with this product.<br /><br />As for verbal communication, I'm hearing just about as well as everyone without earplugs. Loud environments aren't great for verbal communication in the first place, literally everyone is mishearing things just as you are.<br /><br />After about a year of use, my earplugs turned a pretty gross yellow color, but they're still perfectly usable, and these earplugs are so unnoticable that no one notices until you point them out. I bought a second pair recently however, to be prepared for the day when I lose this first pair or if they somehow become unusable.<br /><br />Speaking of losing these though, they might be easy to lose. if you casually screw the case too loose, the case slowly unscrews in your pocket and you've got a pair of earplugs in your pocket ready to fall out. Miraculously even after maybe 10 times of the screw becoming undone in my pocket over the course of a year, I have not lost this pair yet. So maybe this worry is unwarranted. It's not at all a problem with case build quality though, the case's build quality is excellent and the screw-on lid to the case has stayed strong even after a year.<br /><br />What didn't last for me though, is the little keychain at the top that attaches to your keychain. Mine broke after about 3 months of use, after a violent incident of accidentally kneeing my key ring into my car. As seen in my picture, it's been long replaced with a spare key ring. It was a HELLISH time trying to put that key ring on, as the top of the carrying case's lid is very thick and not very suited for threaded inside a key ring.<br /><br />They're good! and hella cheaper than the other choices Amazon gives you!
