Unfortunately, the words "KZ" and "neutral" are an oxymoron! Most of the KZs have a V shaped house sound.
Actually, not picking on KZ, but majority of the budget CHIFI are tuned V shaped or harmanish to suit consumer preferences. There aren't many neutralish gear in comparison, maybe some unique ones like the Tin T2. Tin T2 Evo, HZSound Heart Mirror, maybe some Moondrop diffuse field tuned sets.
Looks like KZ pokemon factory is still alive and well. Gotta be honest, another overears and some quality desktop amps are my next headfi purchases, but probably not until 2022. Speaking for myself, chasing different tunings is a largely pointless exercise. I do have a pair of CVJ Angel Wings (1dd/1ba) and Heart Mirror on their way, and I'm still enjoying the NRA, C12, and BA10 on occasion. I'll check back w/ KZ in a few months when they either release a tribrid or they've made a significant update to their driver tech.
Long Live KZ - I'm on hiatus for a few months as work is in triple overdrive right now! cheers
Really hard to say w/o some more specs. I can't tell if it's actually open backed or just see-thru to the shell. It might just be a re-turned triple-magnet driver without the magnetostatic unit. My curiosity is piqued!
Stock tips are trashed immediately, they are soft, flimsy, garbage TWS tips that, combined with the short nozzle, are completely useless for achieving any kind of seal. The stock cable is pretty good with a hefty strain relief at the 3.5mm jack, soft, light and pliable.
