In general, if they held the charge for the promised time, then it's super, there's no sense in the case. The whole charge is in the headphones and they last for a couple of days, absolutely mediocre listening (after a month of use) Some pros: Sound norms Convenience norms The first month they really keep charging Got cons: After a month, they hold the charge poorly, after a few months you often have to charge very much.
