Headphones are mainly inductive charges. A short cable won't have enough capacitance to change that. (maybe in audiophile crazy-land, that is).

You're pushing audio, not a cable TV signal...
> For resistance you will need to limit the output voltage to ensure you’re not going over the over current limit, or you can get hurt on dynamic range for high resistance loads.
What crappy device are you plugging into a headphone jack that's even an issue? Short protection is common in most ICs.
Or, you know, use a regular headphone with an impedance between 32 an 100 ohms and that should be fine.
> crazy 3.5mm jacks there are it is inefficient to make a product that fits all
What's so crazy about it? Yes, stereo and mic inputs might be unpredictable, but for usual stereo audio it's pretty predictable
People are saying that like if most USB headphone vendor is not going to plug the cheapest DAC they could find and push whatever to the headphone.
