Youtube Video Summary
Softears RS10 targets the top of the detail game at $2,100, but its extras feel dated: a leather hard case, pouch, tips, metal card, and a basic cable—often without interchangeable plugs (current Hangout stock is 4.4 mm). The shell is fully filled resin with a glass-like look that reads premium despite the old-school accessory pack.
Tuning skews a brighter V/U-shape—think JM1 diffuse field (5128) with a bass shelf. Bass is competent, not class-leading at the price; the real draw is the treble: forward, incisive, and surprisingly non-sibilant. RS10 is a detail monster that shoves low-level information to the front and actually has the resolving ability to render it—thrilling for analysis, but intense over long sessions.
Best for listeners who explicitly want maximum resolution and can handle a more energetic top end; less ideal for those seeking a laid-back or warm signature or a luxe unboxing. Price and intensity are the trade-offs; the payoff is one of the most resolving presentations available with a tonality that stays natural-leaning despite its brightness.

Youtube Video Summary
Softears RS10 targets a Harman-leaning reference balance with a clean, studio-grade presentation: bass is tight and linear with modest mid-bass punch, prioritizing speed, texture, and separation over slam. The midrange sits neutral and coherent, giving vocals accurate body without bloom, while treble extends with air and micro-detail that spotlights room cues and trailing reverbs. Staging focuses on pinpoint imaging and layering more than sheer width, creating a precise, microscope-like view into mixes that rewards high-quality recordings.
On the flip side, the tuning’s discipline means sub-bass rumble and warmth are restrained, and the upper-treble focus can read energetic on hot masters. It excels for critical listening, fast genres, and complex arrangements where transient clarity matters, but bass-heads and those seeking plush note weight may prefer a richer set. Build and isolation are solid, comfort is stable for long sessions, and the overall package feels polished and technical—a premium, detail-first monitor for listeners who value accuracy over indulgence.

Youtube Video Summary
Symphonium Crimson lands with a bang: a four–BA, four-way crossover design that somehow delivers epic energy without a dynamic driver. Tonality reads neutral-bright with thunderous sub-bass—not a basshead hump, but a slab of solid, deep extension that stays clean. Mids stay clear for vocals and strings, treble rises for sparkle and excitement, and the presentation spreads out like pulled-apart audio “shreds” across a big canvas. The effect is clarity, detail, and slam that feel bigger than the driver count suggests, making music and film scores straight-up addictive.
Technical notes matter here. Nominal impedance is a weirdly low ~6Ω, so source pairing can swing results; the set scales and sounds happiest on robust gear that can keep low-impedance loads stable. Despite the armature array, coherency stays intact, dynamics hit harder than expected, and volume headroom invites goosebumps. It’s not a “bass monster,” yet the sub-bass authority and lively treble make it exciting rather than polite, with imaging that feels wide and tactile.
Ergonomics are the gripe list: the short nozzle can challenge seal and the premium cable lacks a formed ear hook, encouraging twist and loosening—tip rolling (even reversed-orientation tricks) helps. Build is flashy—carbon-fiber shell, red inlays, metal case that’s too hefty for travel. Pricing sits around $1,500 (or $1,700 with 8-wire cable); for sheer fun, impact, and best-in-brand performance, the value argument holds. For all-day softness, something like Twilight stays comfier; for movies, big scores, and “wow” sessions, Crimson feels like a must-grab and arguably the best Symphonium to date.
