Allerdings musste ich feststellen, das auch ein geschlosseneer Kopfhörer mit den GSX-1000 ähnlich wie ein offener klingt, und der Unterschied in der Klangraumgröße nicht die Nachteile (kein integriertes Micro, weniger voller klang) überwiegt. But I wanted to make this review for those that were curious about the product. I also dont like that it doesnt let u know how charged they actually are. Nice presentation but when you try to adjust the ANC level, hear through level or equalizer, you can easily spend 10 minutes battling with the app for the change to register. CCA-C10 ($46) vs KZ ZSN ($18-24):Looking at the boxes and the units themselves, they are both identical. The product didnt not fit properly. However, the manufacturer decided to apply a varnish or polyurethane to the wood PRIOR to adding the grip tape. The add says to order one size smaller that your shoe size because the sandals run on the large size so I did that and they were too small so dont trust that statement if you want them to fit. It was about then that I noticed the mouse was doing the "color wheel" effect where it cycles between different colors. All connection points are adjustable for a custom fit.
