All tried! This here is the best!

Incidentally: Of course I did not get any earplug which ever or currently are, tasted, but definitely the most popular dozen in Germany and England, which you can get from Amazon. I carry every day earplugs for several hours while reading philosophical literature. In addition, often while sleeping, and all already for several years.

These here are especially good, because of the extremely high level of comfort and at the same time outstanding noise protection.
(Yes, even the ear plugs are indeed good, but:. Too hard !!! not for large Hörkanälen less of an issue at medium and smaller but certainly optimal It hurts in the case, according to one or the other hour addition.. Adapt to logically not quite as good at as tougher and less flexible material.)

So far, hope it helps.
