I started a return but kept it anyway. But sure enough the big kid 5 is too big and the big kid 4 is big but doable. For at least a week. Being that i have a big head I nearly maxed out the size on them and i was perfectly happy. This bag went right into the trash. If you are going to make a necklace, you really need one of these in order to get organised. But so do all Bose wireless speakers. Would not recommend this one. A simple tune up goes for $70 or more so I decided to do the simple work myself (chain oiling, cleaning, etc). Be prepared for a REALLY fun time.
