Personally, when I want ANC in a plane or car, I put on my cans for better sound quality anyway. They?ll hold a medium sized flashlight or other object to your bike. They look great on me and are very comfortable when they are dry. I really hate consuming so many batteries but some toys need that extra power than my rechargeables cant seem to provide or they just drain quickly, thats where these come in. Both the front and back rail are adjustable so they can be at different heights which is great. The fit is true to size I?m a 9/12 to 10 and the large fits perfect. Other than that it is strong and colorful. Exactly what we wanted they are just a bit bulkier then regular crocs but I assume it?s because of the lights. And your cant get the shoes out without scratching them to hell on the sides of the case, as it once again does not fit a 12 comfortably. Fit true to size as per size chart.
