Quality is good and looks just like in the picture. I have had them for a few weeks during this Covid-19 scare so I am wearing them more than I normally would. 5 and that is my true size but I dont think the design is all that great. My tire size is 27. Von daher waren die Werkseinstellungen am erträglichsten. I was worried they would just be another set of cheap earbuds, but thats not the case. (I tend to be the type of person who will wear something until it falls apart. also you cant see anything with the big a** tweezers in the way. The frames popped off several. I have small feet and slender ankles but the straps on these are tight at the smallest setting.
