If you can't find space for a tiny 3.5mm audio jack costing mere pennies in component/assembly price, when even the slimmest lightest smartphones can have them, you are a pathetic and lousy phone or laptop designer/manufacturer. Period. Find another job and another life.
Are people really so dumb as to believe predatory manufacturers like Apple that want to scrimp & save on pennies to screw consumers for higher profits? They eliminate the 3.5mm jack to AVOID having to include a US$5 handsfree wired ear piece. That's 5 bucks (or whatever volume pricing they get) of extra pure profit to their bottom line. PLUS US$199 to sell you a f-ugly looking Oral B electric toothbrush to stick in your ear - with lousy quality sound (compared to Sony as an example)!
My wired Shure in-ears offer far better sound quality than any crappy BT wireless earphones costing 2 to 3 times more! Believe me, I've compared them. Lots of lap tests have also proven it.
Besides it never needs charging - important when I'm in front of my laptop for 8-16 hrs a day! How many times would you have to interrupt your music to charge your BT thingies? And you have to throw it away when the li-ion batteries leak or wear out. That's usually 1 year away.
If I really need wireless functionality for sports like running or cycling,
I can always connect the Shure RMCE-BT2 High-Resolution Bluetooth 5.0 Communication Cable to it.
I can get the idea of Type-C only laptops but that's only if there are at least two or more Type-C ports. The point being that Type-C has far better universal functionality for PD charging/discharging, audio/video output, high bandwidth data transfer/Ethernet/TB etc. - especially with USB4 - while occupying less space than a Type-A USB.
But a 3.5mm jack is still smaller than a Type-C!
In practice, you would need at least three Type-Cs in such a laptop, because one would be used for charging. Any less and you would not be able to transfer data between two external devices directly (out of say harddisks/SSDs, cams, media cards, phone etc.). We're not talking about yet more external plug-in dongles/hubs here!
Which brings us back to the point - using a precious USB port (whatever kind) just to output sound all day is an incredible waste of a precious resource! Its counter-intuitive and only ends up wasting more space on a laptop!
