B+Ocharaku Flat-4 Ti Plus Scorings
Average Technical & Tuning Grades
Average Tunign Grade
D-- Tonally jarring or fatiguing. Frequency clashes (e.g., piercing treble, bloated bass) make extended listening unpleasant. Poor genre adaptation.
Average Technical Grade
D- Limited resolution; finer nuances are masked. Soundstage feels narrow, and complex passages cause muddiness. Transitions lack finesse.

Average Technical Grade
A- Good technical performance. Clear separation and decent detail retrieval in most tracks. Soundstage has reasonable width and depth. Handles moderate complexity without congestion.

As with the other Flat-4s, rather weird and imaging with an intensely shouty and uneven midrange. Crin Youtube Channel

Great technicalities. Lacking that last leg of refinement in terms of coherency. Precogvision Youtube Channel
Symphonium Helios reviewed by: Smirk Audio
Exceptional treble with solid bass. Great techs. Some may find the midrange a bit clinical. Fit will be a dealbreaker to some. Cons: Poor fit.
Symphonium Helios reviewed by: Shuwa-T
Strengths: Clean-sounding monitor with great bass decay. Weaknesses: Occasional splashy cymbals due to the treble extension.
Symphonium Helios reviewed by: Nymz
Top tier clarity and great technicalities, other than a hint of BA timbre plasticness to it. Mid-bass recession is the con in the tuning, turning it into a dry IEM. Top performer nonetheless.
