Since the sound output from a laptop is going to be...not superior..in the first place, is there a legit reason not to use BT headphones?
Sound quality is only one part of the equation.
Scenario: You go to join your meeting or whatever, and you notice the BT headset came disconnected overnight and you have 0 charge.
What now?
I tend to avoid anything and everything that is wireless and runs on a battery if there is a corded plugin version.
Now, all that aside, analogue audio is universal. It works with everything. That is also a huge reason to keep it. Calling it a "Headpone out" port is misrepresenting it too. It is a line out or analogue audio out port. Anything you want to connect it to, you can. An amp, a headphone, powered speakers, a transmitter, a mixing board, you name it.
Sure, you can get a small inexpensive USB DAC, but as has been said before, you shoudlnt' have to. And the part that sucks about dongles is that they always get lost, and are never there when you need them.
I don't think I have ever used the headphone jack in a laptop in the last decade. All my headsets are USB anyway.
If I am honest I rarely use the analogue audio out on computers anymore either. When I do use them, it's because I'm pulling together a last minute solution using stuff I have laying around.
I recently had a meeting I absolutely needed to listen in to at work. They set it up a Teams meeting with no dial in. I also absolutely had to drive somewhere in my 20 year old Volvo wagon.
I was able to pop the cassette adapter in the head unit, plug it in to the analogue out on the laptop, and tether the internet via my phone in order to listen to the hour and a half long meeting during my 2 hour drive. It was a lifesaver.
Sure, analogue wirting is no longer the sexiest thing on the block, but there are still TONS of things out there that use it, to the point where abandoning it is just a profoundly stupid idea. Tech may be obsolete in 2-3 years, but cars, classic amplifiers, radio mixing boards, etc. sure as hell aren't.
