The See Audio Kaguya is a flagship hybrid built around 4BA+4EST per side in a three-way division, using Sonion drivers and a 6N OCC silver-plated Litz cable. The package targets a premium audience with a listed MSRP of $1,399.
Tonally, Kaguya leans neutral-bright: bass is tight and contained rather than heavy, mids are clean with a slight upper-mid lift for presence, and treble is extended yet smooth. Detail retrieval and micro-texture are emphasized, making cymbals, strings, and vocal air stand out without harshness.
Technical performance is a clear strength: imaging feels lifelike and layered, and the stage spreads wider than many IEMs while keeping an intimate, “in-room” feel. Listeners who prefer clarity and treble air over heavy slam will likely appreciate the balance; bass-heads may want more punch. Build, fit, and accessories align with the price tier.

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.
