My hotter take is that this is the same problem as IR blasters, and relative to the old normal -- when device makers like LG were specifically advertising how awesome their built-in DAC was -- this whole thing could be solved in a much more elegant, flexible way if anyone at all would just give us a second fucking USB port.
Sony tried to compete with the best camera, best DAC and I don't think those phones sold. Manufacturers build products the market wants. Wired headphones are not what the market wants. If you are a true purist you buy stuff from fiio and carry more then one device. This is the same thing as with small phones. A vocal minority cried far and wide that they wanted them. Apple made them.. and they did, not, sell.
Every single person wants smaller phones. What do we get? No small phones.
Apple doesn't count… they are priced at 3x 4x what an android would cost.
People want small phones but don't want to spend their whole salary on a phone.
