Unfortunately, these plugs are not suitable for me, because si EPU very against the ear press and are uncomfortable. A direct comparison, the Alpine Sleep Soft are much more pleasant. Unfortunately, the Alpine dams not very good, but what good is a 100% noise, I would have liked to be if I want to rip out the earplugs again ...
That you can not return this product should be made really clear recognizable, now I have purchased 2 Paat useless rubber Dinger for 6 EUR, which I can out of the window thrown betrachtne.
The one star is for both criticisms, even if I know that you're not the dealer rated here but elsewhere.
