> Good TWS headphones are better than the vast majority of wired headphones.

Even not so good TWS headphones are more expensive than pretty good wired headphones.

> Sony's headphones have lossless Bluetooth, and so do Samsung's

Unlike Bluetooth which you have to pray to god that it will pick the best codec, wired connection is already lossless.

> there really is no technical reason why bluetooth headphones have to sound any worse than wired headphones.

... until you enable microphone, then it turns into a potato 16kHz mono stream. A successor codec was only finalized in Bluetooth 5.2 and I don't believe there are major earbuds that support LC3 yet.
