I dont care about the jack, the lightning-3.5 for 10bucks is more than a-ok, that said fuck bluetooth headphones, apart from the “smart” features, sub 50$ cans can and will blow the audio quality out of the water for many of the “entry level” (quotes cause entry is still approaching 100 bucks) BT ones and when you match price it is no-contest.
That said BT cans are still fine but after dabbling with hi-fi I can’t go back to BT.
