>So you used DIFFERENT headphones
Yep. Same price, same components, different transmission protocols, one clearly better than the other.
>plus one headphone paired to two DIFFERENT DAC's (the headphone's internal DAC vs. some external DAC).
Correct. In this instance, the auxiliary connection won again.
I have tried a great many Bluetooth headphones and they've all been abysmal in comparison to their wired counterparts. Because Bluetooth fucking sucks.

>Ah, the famous "golden ear" argument.....
For which there is no counter argument.
