I buy several plugs for its use (mower, hedge trimmer, chain saw, but also for evening or music is too strong)
The result is really good, we do not feel casiment, does not it voyent lot and the most important, are effective!
it does not turn off completely the world, it removes harmful noise.
2positions use, open or closed .. we hear most open, the sound is muffled least, you can even hear the very low while protecting from harmful noise.
In closed position, it really protects many, very useful for places really noisy!
Try it, you protegez oreilles..des protection has 35Euro better than crying in the future because it becomes deaf and there is no miracle cure;)
