In my opinion, it's the best on the market, I had another pair and got this one too because the previous ones have started to wear out at the ears, but only after endless years!!!

Very good sound insulation really. But after a little while, it starts to press on your head and your head hurts afterwards. For sound insulation, it's worth it though.

These are the first and only work headphones I have purchased. They are good and comfortable, although they appear to be durable. Despite this, I expected not to hear anything at all, so I was not disappointed. Overall, the feeling when using them is that you can hear almost everything, but more quietly

It saved me from recent hyperacusis development. I was bothered by the slightest noise, especially prolonged low frequency ones that I couldn't avoid. I had tried other similar earplugs but they weren't equally effective. When I got this one, I didn't need to look for others.

Perfect!!!! It protects from noise because it reduces it to a very good degree for the ear. I asked an ENT before buying it!!!! I highly recommend it without reservation!!!

They eliminate the noise in the ship's engine room, which I use, they are comfortable and adjustable. Very good quality. At €48, I highly recommend them.

The best earplugs I have tried. I used to have some thinner Beretta earplugs and a lot of noise would get through. They cut down the sound a lot, even at the frequencies of human speech. Noise reduction rating of 37dB. They are somewhat bulky, but not too heavy (351g). They are good for studying, but after about an hour of use, you might need a little break. They are also good for sleeping if someone can sleep on their back. They last over time and press on the ears just enough. There are also replacement cushions (HYX5).
