Buy disposable. For the price of these you can get 30 pairs and not have to worry about safely cleaning them.
Every earplug sold in the U.S. is required by law to have a Noise Reduction Rating (NRR) published for it and also the data used for calculating the NRR - the mean Real-Ear Attenuation at Threshold values and the standard deviations of the attenuation values for the one-third octave bands of noise centered at 125, 250 500, 1000, 2000, 3000, 4000, 6000, an 8000 Hz for a group of ten listeners as measured in accordance with ANSI S3.19 Experimenter Fit Procedure. That applies regardless of whether the earplug is intended for the occupational, recreational, or home environment. There is no legal way to have an earplug designed to reduce noise for any application that is free from this requirement. So, where are the data for this earplug?

Unsurprisingly, you can't find a website for EarFirst. I did find a list of the attenuation ranges on the Amazon listing for it.
Hi, do anybody know of the block/decrease the sound of industrial machines with the same level of sound like an angel grinder for example?

Generally you want earplugs with at least a Noise Reduction Rating of 27, for comfort I recommend an NRR of 33. I'll also wear ear muffs over my earplugs if I'm grinding in a small space or enclosed area. (If I'm grinding in a single car garage, it's louder with the garage door closed.)

grinding angels is a surefire path to hell.
These are relatively flat up to 1kHz, but above 1kHz, the rolloff is substantial. ~20dB reduction under 1kHz, up to 32dB reduction at 2kHz - 4kHz. These will definitely provide an appreciable level of protection in a situation where you’re not concerned about acute hearing damage (anywhere where most people are not wearing hearing protection), but these cannot compete with higher-end high-fidelity/flat in-ear hearing protection plugs and they are about 50-75x more expensive than foam disposables that will be more effective and only slightly less flat. For $18, you can’t go too wrong, but don’t expect these to keep up with a professional product or blow away expectations compared to a disposable.

Do you know any good higher-end brands?
Out of all the earplugs I've used on my motorcycle– with and without a muffler attached– these block out noise the best without completely shutting out the street, and they are the easiest to get a good seal.

Ordered sets for my parents. Will see how they like them.
I have a question, wearing this in concerts will improve the perceivable audio quality? usually in small metal gigs what you hear is a mess compared to the actual audio file, will a pair of good engineered earplugs fix or mitigate that issue?

Interesting, i might try buying some decent ones and see, never realized the potential or actual use of these things besides "blocking" noise which a cheapo bag of disposable earplugs would do just fine.

Cheapo set of foam plugs will likely block significantly more sound, but I wouldn't want to block *all* sound while on the highway, just enough to avoid hearing damage while still being aware when a semi is coming up behind me. Similar with concert, will sound better than full-foam earplug, but 'improvement' over no plug would be fuzzy.

For frequency modulation, I can carry on a conversation on the highway with a passenger in my convertible with the top down if both of us have earplugs similar to this in, but not if we had no plugs in. I wouldn't drive with foam plugs in due to risk of not hearing a semi.
Oh, right, Trolls and people who don't know anything about what these are for. So it's ignorance or stupidity that makes people say stupid S**t. LOL
Ah trolls. The waste of air of our society.
So let me get this straight--77 people bought these for $18 a pop and the db reduction rating of -23? And maybe you can sleep with them? Here's some free advice, I've been sleeping EVERY night with earplugs (sometimes in extremity noisy places--and not by choice), for the past five years, and -23db is a very marginal improvement over nothing. I would pay ten times the price for something *appreciably* better, that I actually could sleep with, but I haven't found it yet. What I have found are dirt-cheap -30db foam plugs that do a very good job, and I absolutely can sleep in them. I get them at Walmart for for about nine-bucks per 50 count. You should too:

My apologies if that's the case, although by the insults you were dishing out earlier I find it hard to believe you would find the way I addressed your comments offensive. However, I did in no way mean to hurt any feelings and I simply wanted to have a debate over the validity of this product. On that note, what are your thoughts on what I said? Beyond the offensive part of course.

I was kidding—I’m not not particularly sensitive and you didn’t hurt my feelings. Your comments were quite good and have completely changed my thinking on the subject —and on the meaning of life in general. Many thanks!
