As for the sound, I was rather disappointed, since there are a lot of positive reviews but. The sound is very analytical and reveals every detail of what is sometimes not necessarily desired, at least not from me. Especially the treble sounded in my eyes often to "acute", which after only a few minutes for me was exhausting. Furthermore, I often lacked a bass, the sound was simply "thin". What headphones can be extremely well is fine dissolve. He is thus the opposite of a soundscape where you can barely hear individual instruments. For classical and analytic listening all this is certainly good, but not for hours of "leisure listening".
One should also not be "semi-open" from the name fool you. A soundproofing takes place virtually no.
I have certainly upped the ante still some money and then finally decided on the Focal Spirit Classic. Although the offering of a closed headphone not quite as wide as the stage K701 and detail resolution is a little withdrawn, but he has a little risen in bass and the extreme highs are not quite as sharp. Overall, it sounds a little warmer and I can wear it for several hours at a time without tiring and listening.
