Mediocre, i.e. of moderate quality. Speaking of audio quality here, not assembly. I'd say they don't make the top half, as far as over-the-ear headphones go, in audio quality. And their prices are relatively high, for that money one can buy better sound quality. There's intense competition in the segment.
Show off, yes, as in they look in a particular way (I'd describe it as glitzy) that draws attention to the user. They have that hip-hop gangsta' vibe about them, in my opinion. I expect that showing them in public is about making a fashion or lifestyle statement, not about audio quality.
I don't expect an Apple rework to be less glitzy - Apple is into mediocre, overpriced fashion tech these days.
I cant say that about mine, i really like them. I can say that i don't wear them because i think they look good out in public, i mainly wear mine at home, i have in ear buds for out and about, such as running and in public. I hope Apple expands the range and offers a better selection, they must of seen something, in order for them to have decided to announce alongside the iPhone 7, i think that they have been working on some great headphones to announce.
