Charge up to 1 hour maximum. Didn't charge in the case. Tws F9 for 850-900and then worked for two hours. They were louder and sounded good. And these are not headphones, but money in the trash. Pros below: Appearance design only. It is inconvenient to take them at all, and most often when you take them, they turn off. Has some cons: On all counts, shortcomings. For 616r it's rubbish. I bought xiaomi for 1700r so they are good in everything. Sometimes it is better to overpay in order not to suffer from such feces.
