These ones include a new chip, the H1, enabling Hey Siri and 50% more talk time. They also can be purchased with a wirelessly charging case. I don't know why these aren't considered "true" second generation AirPods.
Because they don’t sound anywhere near as good as my Bloatweisser PH-17XA4 wireless cups.
Sure, the Bloats are over-ear, and okay, they don’t quite meet your ridiculous criteria for “wireless” in that they require a wire to plug into the phone — and yes, they also require an external mains-powered pre-amp which weighs a couple of kilos — but boy do they sound good.
