I am not an audiophile or anything but for these oems a headphone jack inclusion is probably pennys and wired is just superior sound, it's madness.
That said I use Bluetooth headphones mostly myself but that doesn't change the fact its inferior sound, something extra to charge and can add quite a bit of lag when playing games or other media.
Its a step backwards just to make a few pennys profit on a hundreds of pounds device. I think everyone should have the option to choose what they prefer.
