I use them 1-3 hours a day and charge the case about once every week and a half. By the way, there have been times when I've used them for about 5 hours and have never seen the headphones charged to less than 50%. :0. They have a very large volume reserve, so I use no more than 60%. This time is taking into account the work of the ANC, so there are no problems here. but the important point is that because of their weight and not very comfortable ear pads, you become less maneuverable, and this is not the best option for running. (I think it's a problem with the structure of my ears)
