However it does hold up. -When I opened the box, there was some piece of rubber covering the micro USB port. Absolutely love the look, great value! Seems well made, and stands up well to repeated sprints. The off white color is quite white in my opinion. I recommend sizing down unless you plan on wearing them with thick socks. It does a good job on most all genres of music, but loves synth bass! I installed these and at first I thought they were wonderful. Lo compre para decoracion en la cocina. Dont buy these unless you want fake UGGS!
