5-pack Etymotic ER-20 ETY-Plugs (Standard Fit Blue)

I've worn out one set already. I bought the 5-pack to have a set available in different places. I use them at work to take the edge off the back-up alarms on moving equipment, but I can still hear a conversation. I wear one in my left ear when I practice playing my fiddle. That's the ear that sits right on top of the fiddle. I wear them to venues with amplified music and I can listen to the music without pain. I have no problem wearing them for a couple of hours at a stretch and I expect I could wear them for twice that without discomfort. 15db noise reduction, according to the packaging, unlike most commonly used earplugs at 20-25db. Just right for complicated sound environments. I pull earmuffs on for the real loud stuff, like power tools.

These are just the right size for my ears. They do a good job of blocking volume without loss of range or clarity. The little pouch is handy to keep in your purse or on your keychain. The cord keeps you from losing them or dropping one as you put it in your ear. I gave these as gifts because people kept asking me where I got mine. (I've got a decibel app on my phone and will insert these when it gets above the recommended level.)
