Was pretty easy to put together, but the instructions are a little hard to follow (if that makes sense). This is the second pair I use just because the first got worn out. If you?re like me and love to be on the water by yourself, this is a great investment. [Amazon should police this stuff, else the trusted Amazon ecosystem will likely suffer]. My daughter may have worn them twice before the glitter on the toes scuffed off. I bought an inexpensive phone case (which haa a solid back, it will not work well if its rubber and likely will not work at all if its silicone), peeled the adhesive off and pressed it centered on the back of the case. The buds also have a system in which it prevents you from pulling them out the socket so you dont damage the cableCon: the headphones are a little short. UPDATE: It took about a week and they finally loosened up to the point of being comfortable. so i thought i got duped when i first opened it lol. Adding this note here many months after initial review- my only complaint is the sole is thin and flimsy, so if I mistep, it folds under at the toe section.
