They are all based on same chip. So if you buy 5€ BT-headphones and plug them into 1000€ dumb headphones, they very much sound the same as 1000€ BT-headphones.
Also your box can have much bigger battery, does not matter as it is in your pocketsies and not in your ears.

That is not strictly true. While the vast majority of microcontrollers used in BT headphones come from a handful of companies (usually Qualcomm, Realtek or JieLi), the DAC and amplification stage is going to be different. Cheap headphones use the microcontroller's built-in DAC while higher end models can have a discrete chip, or sometimes a custom ASIC that also handles noise cancelling. The protocol itself and the SBC codec are still a bottleneck of course, but in my experience an ESP32 paired to a decent quality I2S DAC module sounds much better than a random cheap BT receiver module (and has no annoying voice prompts).
