Just posting my long-due impression, apologies for all parties concerned.
Thank you for d_marc0 for the chance to audition this wonderful pair
BUILD - In a true reflection of the Doc's workmanship, it is superb as always, hard to fault.
FIT - As usual with all Noble IEM, the body is too small to give me perfect comfort, but that's not to say anything bad about it, my ears canal are big and deep, therefore, not an ideal scenario for small IEM. After a bit of fiddling around, I found the perfect tips that gave me the closest to perfect seal, the large MEElec silicone tips.
SOUND -
BASS - I would say the bass is probably the same level as Westone 4's, slightly leaner, and not as warm. However, the slight roll off bothers me from time to time, especially for listening of EDM's and Hip Hop tracks, but on the other side of the coins, for acoustic, classical,and vocal jazz tracks, it's just a joy to use
MIDRANGE - This is where the magic is, the midrange, hands down, is one of the best midrange I've ever heard, clean, smooth, with incredible clarity and details. Listening to "I Love Being Here With You" from Diana Krall's Live in Paris, every piece of instrument are projected delicately and beautifully, there was not any moment that I feel congestion, nor any distortion whatsoever.
TREBLE - Clean and clear, without any sibilance nor peaks. Flame Trees from Cold Chisel is the song that I use to test the treble and upper midrange in general, most IEM won't be able to get over the sibilance, but this definitely pass the test with flying colours, not only for its ability to tame the song's sibilance to almost non-existant level, but to keep the sparkle and clarity at the same time, not even Dunu 2000J (one of my current favourite) managed to do that.
OVERALL - A bit too lean in the bass department for my liking, but there is no denying that is one of the best dual-BA that I have heard ever
