To avoid noise disturbance, it's perfect. Surprisingly very comfortable (even with glasses) even though tight, as they have very good cushions. For effective protection from harmful frequencies, you go for specialized custom earplugs.

From not wearing anything, it is understood that with these you improve things. And because the strain on the ears, it works artificially, whatever we manage to cut, it is good. They are budget earmuffs, it doesn't make sense to expect miracles. It happens that I also have the Optime 3 from Peltor and I have an immediate comparison when I'm working with the chainsaw, for example. However, I repeat that for their price and their class, they are commendable. If someone wants more noise reduction, they will have to go up a shelf.

I haven't tried more expensive ones, but these work perfectly fine for me when I work for hours next to very noisy machines.

I have bought 2 pairs. They are amazing, they do an excellent job. Wherever I go with my tools, I always have 1 pair with me, whether I use my angle grinder, my electric drills, my electric file, my electric vacuum cleaner. I also use them when my wife uses her hairdryer to dry her hair!!!
