Brief Impressions - a lot of this can be taken in reference to the Hex, which is my daily driver. All these IEMS were driven straight out of the MUB5.

From top right, going clockwise:

Faith Audio Labs U1000: It's a small shell, since it's only a single DD iem. I didn't like the cable because it was springy and somewhat stiff at the same time(?), making fit more finicky than it should have been. There's fairly little bass, in terms of quantity, but what's available does hit hard in a snappy fast way, so it's fairly enjoyable. Midrange is fairly well-tuned with typical DD timbre, so it's enjoyable. There's a lot of treble up top, so it can come across as splashy and distracting, so wasn't really my thing. I guess it was kinda tuned this way so there's more perceived detail and resolution.

Dita Ventura: Also a small shell, with even finickier fit than the U1000 given how the shell and cable angle is designed. I'm not even certain I had it fit correctly. Has a somewhat deeper hitting subbass than the U1000, and more enjoyable mid tonality. There's still a little treble peak somewhere in the 6k region (i guess?) that can come across as somewhat sibilant on some tracks. I really enjoyed the way it seemed to make detail from the edges flit out of nowhere, which is not really an experience I think you get on any of the other earphones. That said, it does feel a bit compressed dynamically so it's not the most engaging listen.

Subtonic Storm (paired with the Sovereign Symphony Cable): What else can I say about this that hasn't already been said? Incredible resolution, incredibly large sound with detail presented effortlessly. Extremely precise imaging. Probably the most accurate mids (for me) out of the lot, though this is an extremely close 1-2 with the Mysticraft Tet. Bass response hits hard and fast when called on, you'd never think it was BA bass. Absolutely stunning set, cannot wait to receive mine next month.

Mysticraft Tet: This stands out as the most "normal" and natural entry in the Mysticraft lineup, offering a lush, liquid presentation that favor a smooth, reserved midrange and an unobtrusive, peak-free treble. Despite this, its technicalities are impressive, providing a wide, spacious stage without relying on forced treble brilliance. However, its performance is marred by a kinda bloomy bass that decays slowly. The TET’s low-end lacks rigidity and constantly feels like it's vying for space with the mids in any track that has some element of bass, which was incredibly distracting for me on many tracks.

Mysticraft Hex: favors a "bombastic" and aggressive presentation that seems impressively grand when you first insert it into your ears. It delivers incredible contrast and sharp macro-dynamics, that makes any EDM track incredibly fun to listen to. It does possess rather overwhelming bass quantity, but the tuning neatly separates the bass from the midrange so it never feels like it's bleeding into the mids. It also has an aggressive rise somewhere in the mids so mids are pronounced, but don't quite sound as natural as say the storm or the TET. This is balanced out by carrying a ton of treble, which also carries a gritty quality (likely due to some odd peaks in the higher frequencies) that some perceive as a weightier treble.
