Snake oil! 23 DB is not sufficient for live performance! If you're a pro, go to your audiologist and get a professional ear mold done and pay the piper to protect your hearing! I suppose these would be fine for non-professional usage!

Mmcx connector at the end, but you have to buy your own.

so what is a good "pro sumer" grade earplug? comfort over audiophilia.

To be fair, those square cut little cylinder plugs are about as uncomfortable as wadding brown paper towels in your ear. They're also only really meant to be worn for 2-4 hours rather then a full 10 hour shift.
it depends on the genre of music. I am a fan of metal, punk, and industrial acts. All of which tend to the louder side. Rock, jazz, country etc all tend to stick to modest SPLs, and as you move up to higher quality venues, the SPLs actually decrease, because they have better sound systems that dont have to melt your face trying to reach the whole audience.

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?
grinding angels is a surefire path to hell.

or heaven, depends on where you stand.

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?
Human hearing is subject to the Fletcher-Munson loudness curve. Our hearing is most sensitive in the range from 2khz to 4khz. And falls off rapidly moving toward the lower frequencies. In order for you to hear flat with earplugs. You actually want an earplug with less attenuation of high and low, more attenuation of midrange.

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?
DI the guitar? I'm guessing you haven't done much metal.

A line out from the amp and/or in line before it. I guess you've never had a guitarist or bassist blow a cone on their stack, cook their amp, or both. It's a simple thing to shift to the line input with processing to emulate their rig (if needed). If you're lucky you have the room in their monitor to keep them happy. - It also allows you (with a BIG rig in a big venue) to let them get stupid loud and not have to worry about them clipping the mic signal, but still reinforce them. I had a metal group a few decades back who supplied 4 different guitar DI feeds because it let them do some $%^&*ing weird processor fades in the FOH mix. (They brought their own FOH guy). Drummer also had a bigger Gibraltar rack than I've ever seen, including in show rooms. They were a hoot. Simple loudness isn't an issue (although it can be). One of the best gigs I ever worked was over 112 dB at the FOH mix position about 40 yards from the stage, and it sounded outstanding. The stage topped 130 at points, I'm honestly not certain how the performers were still able to hear at all after the gig. I'm not sure what the FOH stacks were at, but I was sent up with aviation muffs on to try to figure out which box was failing, and I'm still not sure how to describe the feeling.
