Its pretty impressive. I have to pull the strap up all the way to get them to feel snug but would be nervous walking around in them; afraid they would fall off my foot! its not that much more money than a wax. All 3 straps have velcro for adjustment. Versand zügig. Hoping this second pair is as awesome as the old ones after they stretch a bit. We have been searching for a cover for two years but nothing worked well. They sound even better with Dolby Atmos. The sound quality is awesome, I used Enter Sandman as my first test and it sounds great. Color is dead on.
