Possession of these Vivanco wireless headphones for years! If I do after the evening shift, am again awake half the night & Zocke, movies or whatever with TV it is like on the head "Everts"! Very good coverage, up to at least 10m without radio interruption! Battery power is sufficient. 8 hours continuous operation possible! I recommend, when connected devices with headphone volume control on the headset itself, runterzuregeln this zuerhöhen &. Otherwise he rushes but very & eaten! And that's the crux: listening to music, he is, in my eyes, not so suitable. He distorted but very. What the music heard far more disturbing than if you for example look at a movie! The comfort is not the best, but in the long run it very well what lies "pushes" from the improper shape / size, the listener! For the current price of almost always below 40 3 stars in it! 1 star deduction = Music zuverzerrt / unclear 1 star deduction = comfort Power 3 stars
