Not very durable, questionable color choice

The title says it: For the pigs expensive price of these small foam Nubsis one would expect a somewhat higher durability. Instead, they dissolve very quickly and gradually lose in sound quality.

However, much more annoying is the choice of color: How do you come up with the idea to design things know that cram people every day in their ears ?! Even if you get your own personal hygiene under control - I would now simply once said of me - to the noble bud yellow after a very short time. This is' really not so nice.
