USBC headphones make more sense. Unified port for all accessories.
They remove headphone jack in iPhone 7 and added USB-C in iPhone 15. So for almost a decade the only option was proprietary lighting or bluetooth, probably resulted in a significant amount of e-waste.
It the past it was easy when you could still connect iphone/ipad to macbook via cable and still connect headset for mic and speakers. I tested a lot of splitter adapters and they allowed only to use headset speakers (no mic) and charge (no data)
I'm just tired of losing my Bluetooth earbuds
