I tried out some Monoprice earbuds for about the same price, these are nicer. They do run a tiny bit small for a men’s size but still an amazing slipper at a terrific price. The tips are the same but the plastic is wider. Its made of rubber so its deceptively light, but its also made with a decent amount of rubber so its thick and doesnt feel cheap. It definitely will not protect the case from water. I noticed that the ones purchased on Amazon were made in Mexico apose to the ones purchased from Crocks that were made in Vietnam. Great flip flops and on the thin side, but I love the white colored ones and the price is perfect. I also had people complain that my voice wasnt very clear on phone calls. I dont expect it to last forever, but I have hope that it will take a while to lose its memory :-) Well done. So disappointed about this.
