Further advantages: Apparently this model has also installed a larger battery than many cheaper models, and really comes very long with a cargo of (other reviewers have accurately tested). Comfort: It's been a little more difficult, but is comfortable, well padded, with little pressed against the ears (but would it not be well suited for joggers).
The only minor drawback is (but due to the price / sound ratio but bearable for me, so no points deduction) that he - depending on the Bluetooth transmission power / antenna quality of the coupled mobile phone - in some positions little "dead spots" and short dropouts (often only a few hundred milliseconds) has. Here were some cheaper headphones that I had tested, either a better Bluetooth receiver, or better buffered against such short dropouts. Perhaps that would be a problem during a call (I have not tested), but when listening to music of great sound to me is much more important! What helps me be a better Bluetooth receiver at other cheap earphones if their sound is so extremely much worse than in this model!
Therefore I (mainly for the excellent price / sound ratio) full 5 points!
