I don’t know any who offer weeks or continuous usage. I do know there’s a few with battery life of 30-100 hours (that’s a wide range yes) but that’s just a few days to a week and half in terms of endurance.

If you aren’t a heavy user, 3-4 hours a day, it can definitely last you for more than a couple of weeks

I still use a wired headphone.

You can’t beat the battery life of Infinity. Go non stop for a complete day and even or you forgot to charge, keep using the next day without any downtime.

For me, this is just one less thing to worry about.

Plus, I can use mine on flights instead of their sorry excuse of electronic waste.
