Surprising in a lot of fronts. Maybe a little bit overpriced but I like itSuper* Review original ranking

Vocal benchmark for female vocals under $2000. Clean, airy, sweet, ethereal. Better than Diva and direct upgrade to OG Oracle and OG Mangird Tea. What the Braindamage and Cantor wishes they could be. Great technical performance, and scales decently well. Recommended listening volume is mid to high volume around 75-80dbs. Not for bassy libraries like hiphop, and can be a bit energetic on kpop/jpop/rock stuff with a lot of treble. Jays Audio Youtube Channel

Lack Bass Richness, but is a beautiful set. Jaytiss Youtube Channel
Letshuoer Mystic 8 reviewed by: Shuwa-T
Vocal magic, midrange and upper mids are crystal clear while never being too technical Both sub and midbass presence is less than normal which makes this more genre specific, not particularly suited for bass heavy genres
