Wash it by hand? That too much for me. Good looking replacement caps. Good quality, but it will make your feet sweat which is expected of any closed toe slippers. Received quickly and I was amazed at how much I got for the $. This makes it almost equally adept with edm, rock, hip-hop, or classical. I needed to reformat them from iTunes to mp3 format, which I’m not sure can even be done. Build quality is good but not as premium as more expensive brands. 5 year old has bet wearing these non-stop since summer. I will have to either return this or try to make some modifications. Turtle Beaches have better mic quality but I am done with Turtle Beach as their X12s and X32s did not last long.
