I work in a brewery as a machine operator. These Z/Clouds soles are way firmer and more supportive--so much so that they felt weird on my flat feet. Fit my sons headphones perfect. They charge fast. In the meantime, I give these cables 5 stars. Not a fault of the mount, and easily twisted back. I was able to fit into them but I definitely could have gone with my normal size and had no problem. Everything she needs for school & then some all fits in this backpack. So its great for all ages, so long as it is someone who likes logic puzzles. When I first get it, I felt like it is not strong enough, but after I put my spice bottles on it, it looks sturdy.
