I understand it. I was annoyed by the removal of the headphone jack at first. I have a pair of Sennheiser headphones with 3.5mm and I previously used the adapter with them. I didn’t notice any lower fidelity audio with them and leaving the tiny adapter on the 3.5mm jack didn’t really feel like I was carrying anything more around. I’ve replaced the headphone cable on my senns twice and it was never through use of the adapter(usually because I’d get up and pull my computer to the floor and it fell on the jack), plus the Sennheiser cables are like $30 vs $9 so I’d rather have the adapter fail. I did a sound test with my wife’s Bose QCs and they sounded the same or better than my wired Senns. Now I have my own pair and I don’t miss fucking around with wires at all.
