Most supportive and comfortable. Light comes on but no sound on the phones with it. They are holding up well and I wear them pretty much all day. The cushioning helps my foot problems, the elastic at the top is not tight but stays in place, they dont fall down in the back, cotton content is good for breathability. I was so scared but because I had this strap hooked around the front tire and the strap, It stayed hooked to the rack and didn’t fall off! Build quality seems high all advertised accessories are included with the device! The only thing that bothered me was the headset came with outdated software. If you are the same, then you wont find it here either. They keep my feet dry and warm, and being Crocs they are amazingly comfortable for walking around. This made it incredibly hard to stay focused.
