You can just buy a phone with a headphone jack if you need that. There are plenty options and nobody is forcing you to buy a device without one.

Back in the day they made these ones where it was like a solid piece of rigid plastic that went around the back of your neck and had earbuds at each end. You'd loop them over the top of your ear, and it was a wireless thing. Meant for like runners and stuff. I can't find something like that anymore. I wish I could. It was so much more secure than the little wireless earbuds we have now, and I don't get why they seem to have stopped making them.
