I'll be interested to read the reviews of these and the posts of users' experiences. The current EarPods don't stay in my ears when I jog, but I find it difficult to believe that Apple, which usually pays great attention to ergonomics (with exceptions like the "hockey puck" mouse) would release a $159 product that falls out of the majority of people's ears. I'm sure they did extensive testing with many different people, with many different ear sizes. With the EarPods, it's not such a big deal, because they come free with the iPhone.
One thing nobody has mentioned yet: if the AirPods become a status item, they'll be very easy for thieves to steal in a crowd -- just yank and run.
I suspect there will be aftermarket bands that clip to the AirPods for people who want that extra level of security (I would). I used to wonder why Apple doesn't design their iPhones so they don't need a case: using a material that isn't slippery, and putting a lip around the glass so that the screen won't hit the ground if the iPhone is dropped. I know the reasons: I wouldn't look as sleek, and people would complain that it's "fugly." Plenty of people prefer to use their iPhones without a case, despite the greater risk of damage. And the aftermarket case industry is huge. I'm guessing that plenty of people won't want to use a safety band with their AirPods, and bands will be available for those who do.
As for sound quality, I'm expecting mid-level. I have a pair of LG Tone Ultra Bluetooth ear buds. They're the 2015 model, which I got on clearance at half-price ($44 vs. $99) six months ago after the new model came out. They sound really good, especially compared to the Apple EarPods. They don't sound as good as my wired Sennheiser headphones, but they sound much better than I expected. If the AirPods sound as good, they'll be good enough for most people.
As for whether the AirPods look dorky, well, are they any dorkier than having a pair of wires hanging out of your ears, or a Bluetooth earpiece clipped to one ear? The only reason those don't seem dorky is because we're used to them. I thought earpieces looked really weird when they first came out, but I don't anymore.
As someone else mentioned to those complaining about the 5-hour battery life, a 15-minute quick charge in the charger gives the AirPods an additional 3 hours of battery life, and you can charge the AirPods up to 5 times for the charger before you need to recharge the charger. I think that's fine.
All that said, I don't yet see how the AirPods are an improvement over my LG Tone Ultras. The LG Tones come with three different sizes of silicone ear buds, one of which fits my ears perfectly. The sound quality exceeds my expectations for a pair of ear buds. The band wraps around my neck, and the buds come out on retractable wires, so there's no chance of losing them. I've been jogging with them for six months, so they've gotten sweaty many times, and they still work fine. I can't recall how long the rated charge life is (10 hours?), but I typically recharge them once a week, and the charge level usually is still at medium when I recharge them. If and when they eventually die, I'll consider the AirPods, but only if the reviews have been good and they offer better sound quality to justify their $60 premium over the LG Tone Ultras.
