Technology

There are a lot of very good Bluetooth headphones from Bose, Sony, and the like. If you take a look at lab tests, most of lf them got a frequency response pretty close to the ideal curve, and ANC helps a lot to isolate outside noises that would drown out the music on wired headphones.

But I do agree about choice, just not on the blind refusal of using USB-C adapters. That's unfortunate that they removed it, but it has some good reasons. A headphone jack wasn't made to be waterproof, and if some managed to make some of them waterproof-ish, it is often by enclosing it into its own little sub-enclosure, with a good short-circuit protection (because even a tiny water drop in there mean a short), both of which takes place.
Same goes for the DAC, we got so far into miniaturizing it, and inside interferences are so high now with new technologies, it probably wouldn't be viable anymore to have it inside the phone itself. Even larger device, like the Steam Deck, have problems preventing interferences on the headphones jack, so that must be an even bigger problem on something as tinny as a phone 😅
