And why use your phone’s onboard DAC at that point if you want quality headphones?
Some phones (LG) did actually come with a HQ DAC.
At that point you’re getting a very specific phone for a very specific purpose. It’s not the rule but the exception. So it doesn’t apply as a reason for any other phone. You’ve argued why the LG has a 3.5mm jack, not why Fairphone should have a 3.5mm jack. I’d also be curious as to how powerfully it can even drive headphones at that point. It must also have a stronger amplifier than most phones too. It’d be meaningless without it. What’s the point of high fidelity if it can’t drive headphones that can utilize it.
This is all getting away from the purpose of the Fairphone. It’s not a dedicated music player. It’s not advertising high fidelity music, psrticyij relation to other phones. I don’t think anyone is calling that LG phone “green” either.
Congratulations to anyone who can think of an edge case that wouldn’t apply to the Fairphone. Might as well mention a tensor chip not being in the Fairphone.
