My only issue so far is not the manufactures fault but the fact that I have a small head so they are almost big on me. If youre looking for a daily wear, Id consider something with more substantial foot bed cushion. I am not sure if they have changed something in the build, but they do not last as long (for me) as they used to. That?s how frustrating it is. -Its a pain to connect every time I want to use it with the receiver. As well, my feet are wide and also expand in the heat, but the ability to adjust the velcro near my toes is great. They are easy to clean and don?t even show any wear. The only downside is that they do collect lint/ hairs due to the material the case is made of. Holder has about a 13 in circumference while still velcroing back together I feel that thats probably the largest safest speaker to mount but all materials appear to be pretty tough and should be long-lasting bought as a xmas gift for our grandson.
