These are not shortcomings, but rather features that the spouse drew attention to (they use these headphones): 1. the head is large, so they will be too big for the child. You can increase the size, you can not reduce it - it uses the minimum size. 2. There is no charger included, so you need to charge it via a cable from a PC. Or use the memory for example from the phone. Which is probably not very good for the battery, because. The charger from the phone gives out a very large charging current.
