Joined the drop for the blue 21db "Party Protection". Received them last weekend and put them to use Friday night at a local band venue. They worked great. I could hear the music as well as the people talking around me. Great purchase. The only change I would suggest to the manufacturer is to replace the o'ring on the aluminum carry tube with a flat washer. The o'ring tends to push out of place under compression. But then, I didn't buy them for the container! I've already told my friends they should purchase these for their own use!

OdinkoJust trying to understand what these were for? They obviously didn't seem like they were supposed to cancel out noise and I was curious as to what the purpose was. I was aiming to understand what people buy these for.
CherryMXRGBI'm not really sure how much more clearly it can be explained - earplugs are designed to reduce noise in loud environments to levels that won't damage your hearing.
Cheap, foam ear plugs available at any hardware or drug store work well but they typically attenuate the mid and higher frequencies more than lower frequencies - therefore, they don't work well in concerts because they change the sound of the music. Also, human voice tends to fall in the mid-range frequency - it's hard to talk to friends at a concert or in a workshop when wearing foam ear plugs.
Ear plugs such as the Rooth C&P, EARasers, etc. are designed to attenuate all frequencies equally such that they lower the volume without affecting tonal quality. If you don't go to concerts, or don't need to talk to other people when wearing ear plugs, then you might not care about tonal quality, and foam ear plugs may work perfectly for you.
These ear plugs are not noise cancelling, they are not headphones. They are just earplugs designed to attenuate all frequencies evenly such that you can enjoy life's louder pleasures without harming your hearing.
