You’re incorrect and correct in the same respect.
You’re correct in the respect that the headphone jack still does serve it’s purpose, because there are those who do prefer wired headphones to utilize the 3.5 port.
But you’re entirely _incorrect_ when you say it’s superior, as your misconstruing what superior means in comparison, because that’s completely subjective depending on one’s stance on what they appreciate in terms of either wireless or wired preference, regardless of sound. One could make the counter argument that they *don’t* want to have a wired experience and they would rather sacrifice the sound quality for the convenience of having Bluetooth earbuds that allow more freedom from being tethered to the iPhone. So in that factor alone, you can’t use the word ‘superior’, as that’s broad stroked, being you’re speaking for everyone.
