Ok...UPDATED...
Got an early Christmas Gift today. I've been testing them out all day and while a whole day of testing isn't a complete result, it can give you an idea.
Easy Wins:
1. Tuning on these IEM's are perfect and I haven't seen better...period!
2. Timbre is so realistic and perfectly pitched for voices and instrument representations.
3. Sub Bass a complete beast but once more impressive is the Binary switch style it has with bass when it's needed and when it's not being called for from the music. They sound completely different when tracks have no bass vs tracks that call for them.
4. Separation and imaging, one of the very best I've ever heard ...mimicking headphone capabilities very closely.
Concerns :
1. size of the nozzle could be a problem for small ears.
2. Default ear tips will most likely need to be substituted. I had to use Spin Fit tips before I could even get the proper sound. If I didn't have these ear tips I would have probably sent these back because the sound wasn't anything special at all because the seal could not be established(So make sure you have backup tips in place just in case the default ones don't work).
Extra thoughts: I have heard some people do not like the cable..but I found the cable one of the more beautiful things about this IEM. Love how it doesn't try to hold shape and especially love it how fits around your ears without a lot of thickness like other cables ( they make my ears sore because I wear glasses).
Final thoughts ....As long as I'm not thrown a curveball ...this is easily the best IEM I've tried under $500. Yes, it's better than the B3's and the Kato's or Starfields, Kz's, and anything else. It basically has all spectrums of sound and genre tied up. They have the right amount of weight and reliable material to be dependable under multiple situations without someone having to baby them and on eBay, you can get them for under $300( I did).
