I saw a video where someone posted about this products quality and his experience with this headset. I will suggest go size up . But once I tried to use on another device all of a sudden the language went to Chinese and I cant figure out how to get it back. * Weil das Case etwas flexibel ist, kann man das iPad gut in das Cover einsetzen und wieder herausnehmen. This isnt the case with some other OTG adapter designs. Every shoe I put in fit just fine and it seems to be holding up well. I mounted this on a 29 bike with no problem. Very soft on heal and a tight fit. With buds In an feel the sweat trickle into my ear. These dear foams hurt my feet.
