First of all: The review relates to the in-ear version I was a little skeptical, as one finds outside of Amazon Germany not know much about the headphones (Reviews, Reviews, etc.). By ordering, I am very satisfied! Scope: I use the headset currently in the gym on the elliptical machine and other more slowly / dynamic running movements. This is not to say that the headphones would be unsuitable for other scenarios, but I can simply my experience only refer to it. In the mentioned activities the plugs sit bombproof and skidded at 1-hour elliptical machine sessions a millimeter. The strap (rubber) braces itself virtually to the back of the ear. Since the in-ear plugs even directed a little forward, thereby a certain 'lever' builds up reserves of those things where they belong. In the first few minutes you can feel by a slight pressure, but this is forgotten as soon as good music flows through the Hörgänge. In sports that involve a lot of sideways and lurching, the clamping mechanism is of course more required; Unfortunately I can not share this experience. For sound: Since I have good settings on the Smartphone, I was able to turn out the bass something. Otherwise, I would have been the sound of bass-heavy. Otherwise, the sound is crystal clear and quite crisp on the mids and highs, and clear. The deduction of points in the general classification refers to the Basslastigkeit; People without setting options (or no awareness about EQ settings) may have problems. Basically, rather than around so that you can not at first has the bass potential. But I do not think it's perfectly balanced halt. With phone calls and standby I have no experience. But that would look silly to me out;) --------------- Update after 1 month use: The 4 star has still deserves the articles. On the bass-heavy sound I've gotten used to me and I find it even more pleasant now. Two Kontra-Punkte I can but unfortunately not hide: I use the headset with Android and have no way to know the battery status. This results in doubt, to the fact that I too often charging and a correspondingly probably faster battery wear. Otherwise, I would risk that exposes me during a cardio unit of battery in the middle. Optimal dissolved is not that! Secondly, I have (due to carelessness, but not through negligence) already lost the rubber clamping rings. I hope these can reorder; I still have 1 spare clamp ring is available, that should still go 2 or wear out more for replacements must be found ... --------------- Quick update: Recently the headset has even survived a 40 ° C wash with 1400 revolutions spin cycle. Since then the range is a little worse, sound and functionality are, however, still 1a. Kudos for the Survive this endurance tests!
