Choosing between charging or audio shouldn’t have to be a choose when you consider it’s common courtesy to not spew your noise pollution into your public surroundings. Dongles big enough for passthru charging are too bulky to fit in a pocket comfortably. Now you also have another wire/hub you have to go out and buy & might easily lose or misplace, for what exactly? It sure ain’t to waterproofing or a significant cost-cutting measure. It can let a device be ever so much thinner but does being < 3.5 mm really benefit the user. I bet the manufactures love the revenue of the discount bundled wireless earbuds tho—whose audio is usually not good but labeled under subjective to all but the nerds looking at frequency-response graphs. And when those irrepairable buds can no longer hold a charge after a couple of months, I bet they like banking on users coming back to purchase that same ewaste again from them.
