I suffer from fatigue and concentration problems when I have to deal with a lot of loud noises for longer periods of time. That is why I tried the Alpine Silence at work to suppress these noises and I have to say that I like them very much. I am not bothered by the loud noises of the machines I have to work with, which means that I experience less discomfort from these noises.
In addition, the earplugs are supplied with different sizes of tips, so that they always fit. There is also a handy storage box included so that you can always take them with you and store them safely and easily.
