no jack doesn't mean wireless only. Not having TRRS 3.5mm is a bit annoying but there are lots of usb-a or usb-c headset that have an embedded DAC + you can always use the DAC/USB soundcard of your choice. Also many laptops only had TRS which really killed the appeal of having analog wired equipment if you were forced to use the embedded laptop microphone.
With only two USB-C ports that means you get just headphones and power if you're not using a hub or USB dock.
