Okay, the headset is a bit larger and heavier than my AKG studio headphones - but that is still rather limited. Worse is the constant noise that you can get something under control by adjusting the speaker volume down. Annoying are the constant disconnections and then, if you just indulges the noise and then suddenly startled crashing noise disturbance from a trance! Bad! Not for old people with possibly weak heart. For sound - headphones reinforced already extremely bass and makes the sound fat (falsified these) Compared to a studio headphones - for estimating the neutral music - unfortunately totally unsuitable. Went back. Continue to use the interference-free connection via cable.
