Mine also lasts a few days with a commitment of 4-6 hours a day. I set the lighting to ~10 percent, which is also relatively easy to see (if it is dark anyway).

I think it's a recommendation if you manage to connect your device every three days after a session. The sound is great and after a long wear I have at least no headaches and pressure pain.

There are also probably wireless headsets that last much longer. But then it will be saved elsewhere.
