New MacBooks have both USB C and 3.5 mm ports.

ASSUMPTIONS:

you have a HD800s headphone and a FiiO k9 with USB C, B and both 6.3 and 4.4mm ports. And Bluetooth 5.0.

Now, Apple says:

“For headphones with an impedance of 150 to 1k ohms, the headphone jack delivers 3 volts RMS.

MB also has impedance detection, adaptive voltage output, and a built-in digital-to-analog converter that supports sample rates of up to 96 kHz”

Any technical advantages using USB C over 3.5 jack?

Yes, the benefit of the k9 is better DAC than in the Mac (hence sending the pure digital file to the k9 via USB-C instead) and better amplification than the Mac.

I have a Mac mini myself and run a Ferrum Erco DAC + Amp via USB-C.

If I had a dac/amp of course i'd just use that - why would i buy it if I wasnt gonna use it?

MB’s headphone jack is adequate unless it just lives on a desk. I’m not really fond of lugging around a mess of dongles I need to set up and tear down for some absolutely marginal and most likely imaginary increase in audio quality

yeah, it all seem to sound the same to me....but I'm not a trained audiophile to pick up sound nuances. I do notice the sound is different with Bluetooth, as expected.

Ah OK i understand. It's up to you tbh, just try with/without.

In my case I run a Edition XS and I can definitely hear a very tangible and significant difference - but I think? am not sure? the HD800S is easier to drive? So you can just test it out and decide for yourself whether the portability benefit is worth the difference in SQ

This is too specific for anyone to provide a meaningful answer.

You'd have to try both tbh to get a concrete answer.

If i was using a HD800, tho, Id go external OTL tube amp. Not one of your options, but really is a thoroughly enjoyable (and not particularly necessary) alternative/option.
