Mine were delivered a few hours ago and my observations are that yes, they do connect faster. I did an unscientific “count” (think one Mississippi, two Mississippi....) and it took 7 for the 1st gens to register on the screen when opening the lid. The 2nd gens took 2. When I put the 2nd gens in my ears, they connect very quickly, I’d say less than a second. The gen 1’s take several seconds and sometimes I need to take them out of my ear and re insert them to get them to connect. “Hey Siri” works ok, not great. I have found that certain devices take precedence over each other. If I say it by my HomePod with airpods in, the airpods take the request, if they’re out, the HomePod takes it. This leads me to believe that there is some iCloud wizardry going on which is pretty cool. As far as sound quality, it’s hard to tell. These seem louder than my first gens but I don’t really care. I think they both sound good. I did pay attention to the battery life this morning on my left gen 1. I generally listen to a streaming radio show and started listening at 6:10 am and got the low battery tone at 9:40. When I checked, the battery level was right at 10%. I took it out of my ear at that point and started some background music on my homepods and waited for my new pair to arrive.
