I bought the kit with both the S and M sizes and both have no discernible noise reduction, single use earplugs are superior compared to this

Veel beter en goedkoper dan alle op maat gemaakte oortjes van gevestigde merken die ik gehad heb!

The earplugs are great, easy to use and easy to wear. I have a concussion and all the sounds are demped. I really suggest these earplugs

These earplugs are nice if you want something minimal in look and minimal in noise reduction. I found the foam earplugs to be really reductive and I like that these really just take the main edge off of the noise without seriously impacting the sound quality

After using many different types and brands of earplugs I took a chance on these. These were the most expensive ones I've tried, but much less than going to audiologist for the custom fits. These do, as advertised, contain much more of the clarity of the music, soon you don't even notice you're wearing them. My only problem is they don't block enough. When playing bass in a rock band, I need to be able to hear the other instruments play. With most earplugs, ALL I can hear is the bass. With these, the music is quite clear considering, but only seems like it turns the volume down 1 or 2 notches. If they were about 2-3x stronger this would be 5 stars. My ears still ring at the end of the night, and only have a weak headache, not ringing for days. We play almost every weekend, mostly all bars and small clubs, not (what I'd consider) at huge volume. My peavey bass amp is 250 watt, and on 4 at our biggest rooms we never mic it. Looks like I do need to save my money for the custom fits at audiologist, but these will get me buy until then. They are comfortable, and small enough no one notices and they don't show up in pictures. Hope this helps. Thanks.
