Die Bluetooth Verbindung funktioniert äusserst rasch und problemlos, weitaus besser als mit den anderen Kopfhörern die ich bisher verwendet habe (Sennheiser Momentum, Skull Candy Grinder). These fit exactly as expected, are very comfortable, and great for work so your feet can breathe better! 5 decades. However the 2 pack is actually as pictured, one pack is the bottom rack that holds 3 items and the second in the pack is the top row that holds and additional 3 items. People cant even tell Im driving so thats impressive. Great upgrade for an older vehicle for cheap. The switch to an IEC standard power cord is welcome. I would not have paid full price for them ($70 for cloth slippers is a bit much) but $40 on Amazon and these are a wonderful buy. First shoe I found to check all the boxes for me given my foot size. Organizing your space and taking your time will make for a productive and somewhat educational experience with this product.
