Technically sound, the system S, of course not with reasonably high quality models keep (which he also does not want to). Bass and midrange are matched properly, only the highs come a little too short and so the tips are simply swallowed up like hissing noises in Snare Drums or S-sounds. In addition, the earphones sound a little "faded away". One has the feeling, it would thus build up a kind of Hall front of the ear and thus one has the subjective feeling of the earphone is somehow a bit far away and not directly in the ear. But this will hardly disturb the audience.
The comfort is fully in order. System S delivers with the usual 3 sizes for the rubber attachments, so what should be something for everyone. The earphones press and hold hardly pretty sure (which is likely to make the system S also interesting for joggers).
The noise-canceling is rather weak, because even if the surroundings are a bit quieter, she is still clearly audible. In the noisy subway, or when walking on busy roads close by the musical enjoyment is something clouded.
Visually, the system S In-Ear are rather bland and reminiscent of an all-black version of the Sony MDR EX 85th
Conclusion: With such a price you just have access. Even for the audiophiles who prefer to enjoy their music with the high-end products, acts of earphones to be extremely expensive and at the same time high yet decent spare more than good. And for the casual listener applies here anyway: you! There are so many more expensive, but at the same inferior products commercially sold (especially in large chains such as Media Markt and Saturn), because the system S is simply the best in this price range by far choice!
