Without auszuschwiefen. It does what it should. (Where has my BH504 further blasted a tick) Several connections are possible without interruptions. Control works intuitively. Siri understands me exactly as much as over the iPhone directly. Sound is ok. You can hear clearly his opposite number. The Opposite understands a good but somewhat dull, what is not tragic on. Noise-canceling works well. Can not hear some people talking loudly when they 1m beside me. Announcements "Connected" and so nice. - Where "Battery low" is too often hip, can be heard when it starts with the headset still good 1 1/2 hour music. Music is really clear and distortion-free listening. - Halfway acceptable bass. Although one can expect more for 100 euros which Bass terms. For that reason alone it is not a buy recommendation. (My BH504 has done at least as much) - The woven upholstery above will probably collect fast gel / hairspray / foam / welding. Cushion almost nonexistent.
At runtime, I can not say anything because I songs previously could not make a long-term test at a time.
Overall a nice classy design and excellent workmanship.
Would it, however, settle for feeling at 60-70 Euro
