First, it must be said that the choice of KH is always subjective. Many people want to hear more bass-heavy music. In this case, the KH are mostly very well balanced, that is, they have enough bass and treble, which is actually in demand in the Hi-Fi range. The KH but is less suitable for music files under about 200 kBit / s. Here the poor quality of music is directly noticeable. By contrast, music tracks with high quality can be precisely reproduced very well, which is quite impressive. (Tip:... The most equal to procure a FLAC file with 24 bits for testing and mglw installing a new sound card in your computer thus possible sources of error are ever removed After the equalizer can be adjusted a little (at 1kHz needs of KH something more dB), but can also lead to disturbances of the signal.) The fidelity is very high, which makes undiscovered sounds in the music audible. Technically, there are therefore no concerns. I do not want to judge the sound of KH, which is in the taste of the listener. I'm very satisfied!
The 32 Ohm version is sufficient to hear in any case also on mobile music. The KH-shells insulate strong ambient noise, so you have to turn up overly loud (but of course). The immersion in the music is guaranteed. (If necessary, you can compare open or semi-open KH, the sound changes, but that is again subjective)
Processing is a not feel as one must be careful in size and looks very solid. All items can be bought new from the manufacturer, if anything should go wrong.
The comfort is very pleasant with the Velourohrmuscheln. Listening to several hours at a music is not a problem (even with glasses). One can imagine that in summer the head but also hot.
I can only recommend the KH, as virtually anyone. I assume that the KH now several years working and therefore can one the money be worth. That you regret the purchase, I can not imagine actually. You just get a good piece of hi-fi and no in-ears. Once you can buy but also for much more money KH, I would say that you can open well with this KH. Have Fun;)
