Price / performance excellent 1

In sports the headset holds bombproof and survives any "sweat-attack". While I can understand the telephony other participants very well and vice versa as well. The modifier keys can be also that I can make louder and softer and also a track in front and back can make. By keeping the keys I can also appeal to the last node again. The range is enormous. Tested in a production hall of about 40m from one wall to another. May hold no walls to be in between.

Sonically during music playback, I regret to deduct a star. Here you can feel (listen) is the low price. As a musician and sound engineer (home recorder) I want to say that the highs are a little too heavily cut. The normal music listeners will perceive the sound a bit too dull. So some nuances are swallowed something from music pieces. But you get used to it quickly. Actually, I would give 4.5 stars. Given the low price you can not go wrong really. In addition, the battery performance is truly outstanding. A working day, ie 7 1/2 hour music enjoyment is absolutely no problem.
