Contrary to all the negative reviews I have to come out as a supporter. Easy, easy, easy to use, everything works fine. Bassy? Just a small piece of the situation on the ears change, even the sound is set, the Sensor Bar is awesome, volume shall be regulated with fingers or the entire hand. Call waiting, so Double switches even my phone to the next song. The sound is very balanced, but rather depends on the shape of the ears from, so just move a piece on the head, then changes the sound. The voice quality than headset is clean, all my interlocutors have to certify me a very good intelligibility, despite loud Background. Who wants to do sports: the thing is easy from the head, so Basecap or headband over it, then it funzt. The inner flocking does not tend to any contamination, but as soon crumble as foam. And what was important to me: I have a semi-open headphones, the Cycling enormously important, a hands on the wheel without the To take your hands off the handlebars, the music goes off when a call comes in, only one button to Annnehmen, at the end, the player continues to play. The harassment of the environment is not given in fact, outwards comes almost nothing, even at high volumes. For a Bluetooth headset just fine, but I have to say that I probably 20 kHz no longer expect with my 60 years, because I say in any case the physician can no longer hear. But what do they know that?
