+ Less than other and therefore more suitable for smaller ear canals
+ Good sound insulation for normal ambient sounds (street, fridge, language, etc.), noise loud still be heard!
+ Easy to clean, since smooth surface (porous Schaumstoffstoepsel soak up with water and have long dry)
+ Soft enough for side sleepers: barely perceptible increase in pressure will be directly on the ear
Inserting + good, hold, and take
-Not really small enough for small ear canals ('m male, 190cm large)
Will need to look around further and report if necessary
