Hat eher was mit Klangästhetik zu tun und: solange mich meiner Leute verstehen, ist mir persönlich der Klang egal. They also hold a charge for a extremely long amount of time. Im petite 5 feet tall and ordered the Small. I am an adult that doesnt change her earrings very often. it started right up without being affected. They look good and my Son hasn?t complained about anything with them so far so win, win for me. Easy on and off and very durable. Decent price if they last 3 years like my previous ones did. With the air holes my feet can breath and I don?t have to deal with socks and sneakers. I have in between 42 and 43 EU number.
