I like personally and adjust the soft silicone earplugs very good. Other well-rated models were too tight for my ears or big and very uncomfortable. This material adapts very well to the shape of the ear canal and is comfortable to wear. When intensive swimming it can happen that a little water gets into the ear canal. Unfortunately Ohrenstopsel were delivered to me in green, although blue was depicted when ordering. Ultimately, seems to be crucial the individual shape of the ear canal for the right choice of earplugs. I am very satisfied with this product.
