Pros: Well, they do make noise. Sort of
Cons: Not worth even opening
I don't know whether it's a conspiracy or a joke, but Apple's talk of these being good quality just makes them seem like hilarious liars who could sell ice to eskimos. If their intent is to drive aftermarket sales, then they've managed it. As far as I can tell these things literally don't play bass. It's just not there. The midrange is ok, and if you're tired, they're ok for watching movies with because they delete the thunderous parts of the soundtrack and preserve the voices and background noise quite well.
The only possible use these really have is as a marketing tool to see how many people are wearing them and therefore fell for the marketing and sales speech. It's a lot.
Oh and they fall out easily and they snap quite unexpectedly if you drop them on something hard.
