I wanted to replace my hitherto used semi-open earphones (aka bud) on the go and jogging. This requirement has been very well met. Sound: The bass was initially very violent for my taste, as I am used to only the weak basses of the plugs. After 15 minutes, but it's the bass that makes these headphones so super. In addition, it confers a very balanced sound in all frequencies, ie you do not turn up loud equally loud to hear all the sounds. Contrary to so many other opinions here, I have the same time as a high-end headphones for zuhaus bought (Sennheiser RS130), and thus know what is right and wrong. Trust me, the bass must be so! Wearing Method: It is promised the overhead application and a neckband application. Overhead holds good, though not perfect, but for jogging reichts all. It expresses and hurts nowhere and the pressure on the ears is also just right. Neckband is quite makeshift but well resolved in my view, simply by the bracket is tilted about 90 degrees. But here he pressed something on the tops of the ears and is therefore of limited use. I recommend clearly the overhead carry. My predecessor complained about the "telescoping" of the temples etc. I can only say, it's not a bug, it's a feature. Frankly, I find this feature even good! Ie, the top of spring steel? existing 2 elements always automatically adjust to the head size. If you want to put it, you have just put on the headphones and the elements adapt automatically (with some force) to the head size. But I recommend after that readjust upwards to fit will optimally. This is also true for the neckband thing. Design, processing: rickety. But that is I do not care, because i like the sound and the carrying method was the most important. In addition, you can see the thing out, as if one comes from the 60s, but their spots you have to jump, unfortunately, if you want to have really good sound on the go. The cable is run very smooth, so it is well suited for the sport because it is not very liable to the sweaty skin. The collapse is quite nice, as well as the to small but useful leather Sackerl, but this "feature" I'll never use it well. You have yourself a little deal, until you find out how the folding works, but it works. 4 points so because it (presses Neckband version, rickety, cheap look and you look like someone from the 60s from) a good product with a few small flaws has. EDIT: Well, I have now used this headset for about half a year and my opinion has changed decisively! The right speaker has a slight fluttering in bass and is thus no longer be used properly. I guess that this problem resulted from the rickety construction. The basses are extremely contrary to my assertion. Nurmehr 2 points for premature product failure
