Are you invalidating all of these measurements?
Saying that technicalities cannot be measured?
You guys sure do measure an apple dongle and say is all you really need.
But when it comes to technicalities everyone agrees that they are subjective?
Because no matter what everyone can hear different things then when the technicalities are totally the same. For you a headphone might be perfect, crafted by God’s own hands and other might call it hot garbage.
