Got mine yesterday, yay my custom tips from my old Super 5s fit! Great packaging and generous supply of tips/extras. Definitely lives up to their original pricing from that standpoint.
Here's my quick first impression:
Sound Q... is OK. I'll need to put a some hours on them and compare them to few of the IEMs & cans I have, give a go with a few tips, sources, and see if the other cable matters. Keep in mind I'm not intending on listening to anything beyond 320 MP3s on an iPhone 7+ with them so YMMV if you use better source material, amps, etc. I'll probably give them a go on my PC setup (onboard>optical>HK 6xx avr) just to see if a decent amp makes a difference, I recall the Supers responded well to some amping giving a small, but noticeable, improvement. I just don't plan on using them like that on a daily which is where I'm keeping more of my focus.
Right off the bat though I'm pretty darn sure these are NOT like my Supers which had a pretty flat, analytic, sound that I compared to AKG K701 at the time (~10yrs ago jeez!). They seem a little bright, not painfully, just a bit more emphasis on the upper range; sound stage is something I don't typically think about but in this case I noticed it feels like it's all right on top of me - it's a bit claustrophobic if that makes any sense. Like I don't need Mark Foster in my lap man, get back on stage. I'm not a big believer in break-in but hopefully these do a bit.
Just to give you an idea of where I'm coming from Grado SR-325i, Westone ADV1s, Koss Porta-Pros, and Apple buds are the most common I use. The Grados have my ideal sound signature but I did like my old Supers for the occasional analytic session.
I'll do my best to swing back with more thoughts once I've given them a fair shake.
