Very good purchase. I used them at music festivals and I feel that they really protected my ears, without diminishing the enjoyment. You can hear everything, just at more normal decibels!

Very good in terms of reducing sound without distorting its characteristics. It is also impressive that you can hear the surrounding conversations very clearly. The only drawback, and for that -1 star, is that if you make the mistake of inserting them too deep into the ear, you will need tweezers to remove them.

They satisfactorily reduce the intensity of loud music without significantly altering the sound quality. I have tried them at concerts and in clubs, and my ears were not bothered at all after hours of loud music. It is also convenient that speech can be heard comfortably alongside the loud music.

Very good quality, etc, etc, but guys, for someone with slightly bigger ears like mine, they are too small. The right earplug decided to explore the depths of my labyrinth and it took effort with eyebrow tweezers and Nikoulouli to retrieve it to the surface. So be careful. Okay, I put the cord they come with and it holds them, but firstly they are not so comfortable with it and secondly I got them transparent so they wouldn't be visible, not to have a black cord piercing my head.

Okay, everything is fine, whatever. They will do their job, I just got a bit annoyed with the above, considering they are not cheap. That's it. Have a good concert.

The earplugs are very effective. It is impressive how well they filter the music, while speech remains clear.

They are very good for concerts and parties that have very loud music, slightly reducing the intense frequencies without compromising the sound.

Although they work well in uniformly reducing the volume of sound, they present increased difficulty in their placement. They are slightly large and it is not possible for me to lift my ear with my hand above my head in a concert venue with 3,000 people to put them correctly in my ears. *Regarding a previous review: they do not block the sound, they simply reduce it. So anyone planning to purchase these earplugs to not hear any noise would be better off using traditional foam or wax earplugs* :-)
