I purchased these to go with a dress for my baby shower, so I wasnt on my feet too long. The cover for the case works. They battery live is amazing! The connectors enable much larger speaker wire, again at a great price! I just recently purchased this product, TPI-PRO IPX7 Bluetooth Professional Wireless Sport Earphones w/Mic Waterproof on Amazon. Amazon were good in picking them up and refunding though. Smaller size ? not so visible ? easy to hide it from boss and others at work3. The Rondo seems to be very small to wear. Size 11. She crawled over to me with the shoes in her hands for no particular reason yesterday, and after I strapped on the shoes she stood up and happily began stomping in place.
