Pro:
+ Small
+ Do not interfere with sleep
+ Reusable
+ Ventilated (air circulates inside the ear)
+ There is a pleasant feeling not entirely sealed off from the world Being no noise as in normal "ear plugs"
Contraindications:
chutes night continued into the ear
vapors only slightly (about half of a "earplugs" hearing protection)
-man has the feeling they do not always include richitg from (too large fins be this gewölbt- arise there "slots")
Not being able to wake up and grab his earplugs in your ears moved me here to give only 3 Stars.
