This problem has solved this product, they sit bombproof.
Material quality is fine, it will be easier, but competing products cost like three times.
Also, you can wear them without problems for a long time.
The screen is mediocre, somewhat worse than the Silkon cushions.
Sonically, there was however a change: bass were weakened, the headphones may sound relatively neutral. I would not say bad, rather different. Who's In-Ear therefore something wants to take the bass exaggeration, nothing makes here. Mids and highs have hardly changed.
Addendum:
Meanwhile, I had the opportunity to compare them with Comply Foams.
The surcharge on the better product worth definitely, Advantages:
The change of the sound is considerably lower, the Abschrimung is much better, where the material feels better.
After a few months (not daily) use this cure here from Pearl on the material already something out.
Again I would not buy it. 1 star deduction of the initial assessment, because if you want to have his in-ear something neutral and cope with low Abschrimung or wants to have so, they are still a good choice.
