Natural king. Special iem at any price.
Youtube Video Summary

Custom-built shells and faceplates make Supernova feel special from the start, and the ergonomics seal the deal: a light, durable shell, super comfortable fit and a supple, well-textured stock cable. The tonality stays open, clean and free of sibilance, with imaging that snaps into place both horizontally and vertically. Detail retrieval in busy scenes is immaculate, making it superb for long gaming sessions—not to farm K/D ratios, but to elevate the overall experience as in-game micro-details sparkle. Tip rolling works well (SpinFit, Divinus, Latex H70), though the included tips are decent; the clamshell case is nice, if a bit annoying to twist shut.

Versus peers, Supernova shows almost perfect tuning with exceedingly strong technicals and a touch of juicy, lush timbre. Against Night Oblivion Butastur, the overall tone and bass texture on Supernova are a hair better, while Butastur gets you 95–98% of the way for less and shines for classical and pop. Compared with Monarch Mk III, the FR curves are scarily close (within a couple dB), yet Supernova’s treble refinement and stage feel a tad more convincing, even if Monarch brings different technical strengths. Net takeaway: a holographic, genre-agnostic performer that’s easy to recommend; the only real caveat is the long wait time to get one, and the bass could use a touch more authority.

Unique tuning, but the switch would be better in the mids or bass.
