Some of the parts even look hand-soldered, where Id expect plugged-in components. My daughter loves this charm! The little red plastic peices that clamp on the bike do tend to fall off, and it would be nice if the straps were permanently attached so I didnt have to worry about keeping track of them when the bikes arent on. The sound really is good, without earplugs. I tried these and the sound quality was surprising really good, better than I thought they would be considering the price point. It is entirely unpadded and tore my skin up after a few minutes of wear. Very light weight, not heavy. Unfortunately Im stuck with a handful of spices Ill never use (or even heard of). They get uncomfortable about about 3 hours. once your feet are wet they slip terrible inside the shoe and you really have to be careful not to slip and fall.
