One negative for me is the poor ergonomics as applied (at least for me) by (to) thin foam pieces a strong pressure on the ear, so that with me after a longer use of this protruding part of the ear begins to hurt. Therefore, a star deduction. The cable already holds despite frequent use at least more than 1 year, which is ever better than the Porta Pro, which I had previously (and compared sounds dull).
Unfortunately, there is the hard case of the previous model no longer, but you only get one of those impractical bags supplied, the one eh never used.
Overall, a good headset for the home, where one does not bother anyone. For mobile use rather less usable.
