Does wireless charging meet the same performance levels of wired charging? Doesn't it take much longer to do an induction charge? It's like a lose lose here. Poorer audio quality with bluetooth, slower charging with wireless....
Much longer? No, unless you're comparing to using fast charge with a 30W charger and USB-C to Lightning cable. Somewhat longer? Yes. 7.5W is common for induction chargers. Apple's iPhone chargers in the box have long been 5W; I don't know what the wattage will be on this year's iPhone chargers.
Won’t do you much good, though when you’re trying to charge and listen while waking or in a moving vehicle. Unless what you mean is contactless charging - which would be ... interesting ... in public spaces (street or transit).
