But whoever buys these headphones, which is probably also the volume control important. You do not want to get absolutely every time the smartphone (or MP3 player) from the bag yes. However, the regulator is a bad potentiometer and no remote control. Only on the "maximum" setting the sound is good - including there are two problems: It is difficult between "loud" and "too low" to hit the right spot, and then the two channels are also suddenly no longer identical.
Since I had to completely renounce a function and had to instead revert to the volume control on the source, there are two star deduction. Too bad, because otherwise this is a super headset.
