They may have a usb-c charger they want to use eg for a laptop. By making it lightning on the headset side they just reinvented a corded headset.
Regardless, this complaint is pretty spurious. The device is clearly marketed to iPhone/iPad users, who carry a USB to Lightning cable with them as a matter of normative standards.
People just like bitching sometimes.
I have a battery pack that doesn't charge with a lightning port, and can charge my phone without a lighting port (wireless).
When I'm traveling light, I don't need a lightning port for anything.
When I'm at my office, I can top off my headphones/iPad/etc off with the same cable I use to connect my laptop to my screen. I never have to worry about bringing an extra cable with me to work.

It's just too bad, that's all. Apple seemed like they were ready to phase out the lightning port in favor of USB-C and wireless charging. They've done such a great job with all their other audio accessories that a lot of tech-minded people like myself were looking forward to these.
I personally think it’s pretty silly that it has neither usb-c nor wireless charging, given the price point and when it’s being launched.
I get I'm not the target market but that doesn't make my point valid. Please don't negate it as bitching.
