Thieaudio Monarch Mk2 Reviews
Neutral tuning with one of the clearest mid-ranges. Natural and clean vocals. Great resolution, separation, and detail. Can be a little dry with its analytical presentation. Bass is well-seperated from other instruments, but nothing special especially at $1K. Would've liked more depth, and treble is also a bit unstable and dips, resulting in a lack of air/depth. Mid-bass is just enough for my library, but would've liked more for genres like hiphop and rock. Cable is heavy, and fit may be too big for many (need to shove in deep). Jays Audio Youtube Channel
Too much unit variation to recommend to others highly. Jaytiss Youtube Channel
Outstanding tuning. Smooth, balanced tuning with natural vocals, beautiful timbre, and excellent tonality. Detail and could use more bass. Treble depends on ear tips.Gizaudio Axel original ranking

Organic midrange Wooly bass response and less prominent treble may not work best for certain genres
Good treble with tons of air. Forward, ethereal mids. Good detail retrieval with tons of microdetails. Lackluster mid-bass.
Cohesive, smooth, balanced, technical slight treble wispiness Tim Tuned Youtube Channel
11/10 mid-range. Mid-bass could use more texture and stage depth could be better. Yap, that's all. Oh and the fit - I'm blessed, but you may not be.
A solid improvement in imaging with slightly more palatable tonality than its predecessor. Precogvision Youtube Channel
Symphonium Helios SE Reviews
Best Treble around it's price. Super airy but still smooth. Bass-scoop isn't as bad as I thought, but those who want mid-bass - avoid it. Jays Audio Youtube Channel
Limited to 50 units. A huge improvement fit wise versus the original. Great TOTL all-rounder. Great sub, upper mids and treble. Mid-bass is an improvement but still not boosted. Great technical chops while fixing the sense of plasticness the original had.
See Helios but with more mid-treble and mid-bass. Precogvision Youtube Channel
