I've got the Vmoda's and have had them for quite a while. I've used them snowboarding, at home, and every time I go to the gym and they're a great all around IEM. They're built well and have withstood my tossing them around and leaving them in cupholders and putting things on top of them. There's no issue with microphonics but the cable does have a bit of memory. Not a big deal for me.
I'm certainly no expert and haven't owned any high end IEMs so I don't know that I'm the best to judge but to me they're great. I had a pair of Sennheiser CX300's until they broke and some other cheap ones until I got the vibes. The sound quality is very good just keep in mind I don't have a lot to base this on or compare it to. The Meelec's get a lot of love on here too. I have a pair of IE7's on the way but regardless of how good they are, the Vibes aren't going anywhere.
