ljokerl, and any other with wide experience with IEMs, I would like to ask for some orientation:
After "discovering" the Vsonic GR06 thanks to this thread, I started to have the "itch" to upgrade, so the quest began...
I don't use amps, the IEMs should sound fine with a naked iphone, ipad or ipod.
I love the GR06 for their superb qualities in terms of bass and music enjoyment, I hate analitic IEMs and these made me wanting to keep listening to all my music. They're not precise, but very fun and enjoyable.
They can of course be better in terms of detail, precision, "cleanliness" and imaging.
I tried the rockit sound R-50, not my cup of tea: inexistent bass, tooo analitic, too fast.
I got the GR07 BE right now. After letting them 300 hours of burn-in, I'm starting to bear with their initial unbearable, harsh, brain-grating sibilances.
They are a significant improvement in terms of detail, imaging, speed (w/o being tooo fast), and overall "balance".
My ideal sound signature: IEMs that make most music (Rock, Pop, Indie) sound enjoyable.
Most of my preferred songs belongs to BritRockPop genre (Travis, Richard Ashcroft, Skunk Anansie, Coldplay, Stereophonics, etc...) are exquisitely produced and mixed, but my music tastes are rather wide, from Heavy/Nu metal, Grunge to Jack Johnsson, Reggae, etc. (almost anything but Classical) and some groups (Red Hot Chili Peppers, Metallica) Mids in their mixes in combination with IEMs that portray mids in a "rough" render their music unlistenable for me, when the feeling I'm looking for is to want to keep on listening and listening to more and more music.
My ideal IEM: powerful, defined bass and subbass, detailed, slightly laidback mids, and silky, lusty smoooth airy highs, while keeping instrument timbre, nuances, etc.
Though I prefer to trade enjoyability to precision anytime. I'm not working with or analyzing the sound, but ENJOYING.
That's what made me think about the hybrid IEMs combo, guess the point is getting that bass/sub bass presence with a dynamic driver while letting the precision and silkyness in mids/highs to BAs???
I'm aware of the upcoming release of the V7007. Do you think guys these could be just what I'm looking for?
However, I always have problem to get a good fit with universals. One ear cavity is smaller than the other, the earcanal seems to go in a upright direction making fitting universals rather tricky, etc... So the initial un-thinkable option of getting CIEMs started to fly through my mind, as IEMs/iphone has been an unbeatable combo and option to enjoy music ANYWERE, so I will definitely recover the investment.
I wonder how would UM 3DD fit my tastes, though they're all dynamic, don't know if dynamic mids/highs translate to roughness/harsh sound, or simply could not be as detailed and fast as BAs, which could be a plus for me.
ljokerl after reading tons of your reviews and comparisons I think you hit the nail in every on I have owned, so your opinion/guidance is very appreciated!
