Eppure cè un difetto che proprio non riesco né a capire, né a tollerare. I bought these since I run outside and want to be aware of noise around me, but even at full volume the music is completely drowned out by any passing car. I did often rotate the camera and that did work very well. When they did work, sound quality wad good. It turns out Cohen with scripted actors, without the usual danger of being exposed mid-scene by real-people dupes, is not so compelling. Fazit: nicht billig, aber preiswert erscheint mir hier die perfekte Aussage. I love all of the different features. Having said that the sound is amazing and I think some of the issues was not knowing how to use them properly. It took about 90min total. Then to make matters worse it seems I have two very stiff planks of wood strapped to my feet when i walk in them.
