Clicking on the image in my original post should open a larger version in my gallery. I'll re-post here as well anyway try clicking on this one and tell me if it works.
I'm listening to my V3s through the Fiio X3 (no treble or bass adjustments) and th
ey come across as warm and musical. Not analytical but very clear, the isolation they provide probably has a bit to do with that. They sound pretty awesome. Was just listening to Gossling (kind of an indie rock/folk artist). Switched to Miku (I don't know of anisong, whats she like?) and out of the limited headphones experience I have had, folk/pop vocals sound fantastic on the V3. The main headphones I can really compare these to would be the MadDogs by Mr. Speakers which are more analytical and have much less bass impact. Personally, from the research I did, I figured the quads or the V6-S would be too bassy and the V6 too analytical (though I imagine you would experience a fuller sound with better sound stage on the V6/V6-S, not that I believe the the V3 falls short in those areas).
Mind you this is the first pair of CIEMs I have owned and you may want to get some more advice.
If you haven't used CIEMs before I just want to say be extra careful with volume. I have my X3 set to reset the volume to 5 every time it turns on and usually this is all the volume I need for the V3s(had volume as high as 24 when using with other headphones).
Hope this helps
