I use wired headphones easily 80% of the time I use any electronic device capable of sound, and >99% of the time I’m actually listening to that sound. I would sooner take a phone without speakers than without a dedicated 3.5mm jack. (I could be convinced with two USB-C ports though)
I don’t need more weight on my ears, another thing that can die, either buds that can be lost or an all-in-one that can’t survive my pocket, and I definitely don’t need another drain on my phone’s battery. I’m not against Bluetooth headphones in general (I do use an over-ear set occasionally), but they will never be my go-to.
A proper poll on use time/duty cycle would be interesting.
