> It's interesting to me that Apple made such a large fit change without considering 2's are simply better for some people fit wise.

I immediately ran out and bought aftermarket foam tips for my 2's since the silicone ones never stayed in. Apple is likely trying to fix that kind of problem (and may have done so on average entirely successfully) but now you're seeing the people that it doesn't work for show up in these comments. This comment section is going to be biased towards complaining about the 3's so you can't really judge if what they did was effective or not on average, only that clearly it wasn't perfect.
