...which is how you slowly erode standards for both twisted fun and massive profit.

It's sad and pathetic watching this mission creep of audio degradation at the greed-fueled discretion of corporate profiteering.

Phone DACs aren't very good. I use a very expensive DAC when I listen to music at home because I actually care. I also own a pair of AirPods because in a noisy city environment walking around it doesn't actually matter that I'm losing fidelity.

Simply incorrect, at least on the Apple side of things. Android DACs and onboard amps are hit and miss.

He's done similar measurements on other Apple audio devices, including their $9 Lightning-to-headphone adapter and they all fare well.

As I commented elsewhere the problem with Bluetooth is fatigue related not listening pleasure related.

Edit: As a side note the only positive I can see out of removing the headphone jack is the potential proliferation of quality DAC/preamp dongles. Still annoying though.
