Would recommend buy on this wind -screen with the great adjustable arm, The sound quality is definitely comparable to skull candy if not better and the yamay ones are noise cancelling. Humorous read, well worth the price Mine was a medium about 23 inches long. I am giving a poor rating because of the high cost and poor customer support. I put on some knee highs and that problem was solved. Dennoch ragt die Ferse drüber und an den Zehen hat man übertrieben gesagt noch meterweit Platz. The device is physically what you expect. Walked everywhere that was our goal, these were the shoes. It’s rattles like crazy while I’m riding my bike and I don’t anticipate it will lasting terribly long.
