It?s made of leather, it?s sturdy, fits the Air Pod case well and has a strong carabiner. These are great and fit the bill. Buen modelo, buena precision, buen software. It took a little time to test various heads on different parts of the body because I have very sensitive skin and wanted to avoid any irritation. While there is space at the front of my toes and behind my heels this is how I prefer my sandals. So far they are comfortable, wash up well, and don?t end up over my head while I?m attempting a downward dog. So far so good on our IPhone 12 mini it?s charging it pretty after 60 minutes up to 70% from almost 40%. Received product in a timely manner. I ordered the soundbar, bass module and the surround sound speakers. The length isnt too long that they trip her or anything.
