Music can therefore, at least incidentally, best not too loud, hear, in no way comparable with smartphone croaking. That one has to make do with an analog line input is therefore for me, given the sound ok, although I would have liked to pay a few euros more for a digital docking.
Highly recommended also for teachers, tutors, etc. The device brings dialogues clear and pleasant in a seminar room and adjusts this as a spectacle comfortably in a briefcase.
