My Vibe's just turned up. They look good, feel good, and sound like ****.
Wish I'd read this thread before I purchased them, but actually wound up reading it in the interim while I waited for them to show up. Mine have the knurled plug, and a black case... not sure what gen that makes them.
These things are just way too bass biased, the highs and mids are both very average. I wouldn't say muddy, they sound clear enough... but just way too heavy on bass - unbelievably so. It's almost funny, except that I paid money for this joke. I have a very extreme EQ setup at the moment (diagonal line falling from treble to bass) and like that they are bearable. I'll give them a while to burn in before I give up on them, but so far, I'm much happier with my EX71's and wish I hadn't wasted my money.
I think this whole experience has turned me off even remotely expensive IEM's (yes I know, vibe's are cheap compared to some of the other stuff out there) and I'll probably stick to cheap sony/panasonic/etc IEM's. How hard is it to make something neutral, everything highend seems to be biased towards highs or lows.
