These specific earplugs are excellent and softer and more comfortable than the orange 3M ones. I wear them during sleep for snoring and internal/external noises and I have found my health. It doesn't completely block the noise, but it reduces it to a great extent, so it's not bothersome. For better fit, rub it between your palms for a few seconds until it takes a minute shape and insert it deep into the ear immediately before it regains its original volume.

The best earplugs with sponge tips. They are slightly smaller in size, do not tire the ear, do not come off during sleep, while the others slip due to their shape, such as ohropax, quies, or are not as soft as the 3m ones. Unfortunately, I do not easily find them, although they are worth it and they are also cheaper. They do a good job in sound insulation, they may lose very few decibels compared to others. Of course, for heavy-duty situations, more practical solutions are needed.
(The review applies to those with rounded edges, NOT the square-oval ones)

It provides basic protective coverage for drums, suitable when working with wheels, hammers, and light manual labor. Simple and useful.

However, the orange 3M earplugs isolate slightly better.

I expected greater sound coverage based on what I had read in the reviews. They cover to some extent, but you have to put them deep inside the ear

Take them wherever you find them to have. The only ones that don't bother and effectively cut as much noise as they should. At first, I got these with the string because I couldn't find them without, but still, it doesn't bother at all during sleep, it's like it doesn't exist.

Awesome and very cheap! It doesn't bother, you can easily lie down on the pillow and you hardly hear any noise

They are very soft as if you are not wearing them and they cut the noise as much as needed to sleep or read.

I have the same earplugs but without the string, and I believe that these 3M ones with the phosphorescent yellow are the best earplugs - sponges. Much softer than the classic yellow cylindrical 3M ones that I know well because I have been using them for years for studying and sleeping, comfortable almost like silicone earplugs and effective.
