Symphonium Helios SE VS Symphonium Titan

Youtube Video Summary

Symphonium Titan delivers a bass-centric tuning that keeps its house in order. The mid-bass is tactile and textured with satisfying slam, while the sub-bass reaches deep, rumbly, and clean. Crucially, vocals remain clear and the treble is well-extended without harsh peaks; there’s a small 5–8 kHz rise that adds excitement and “snap,” yet overall control prevents bleed into the mids. The stage feels big and open, and the set avoids excessive warmth, making it a genuinely balanced bassy IEM.

There is a caveat: that 5–8 kHz lift can come off a bit sharp on forward-snare or energetic K/J-pop and hip-hop tracks, so the Titan shines best at mid volume rather than cranking it. Even so, it stays smoother than options like Maestro/Scarlet Minis, offering better extension and less fatigue while keeping the fun. Scaling is above average, and the overall presentation remains engaging and authoritative.

In comparisons, Titan reads as a direct upgrade to Monarch Minis (bigger stage, less fatiguing), more balanced than Scarlet Minis (which chase sheer slam), and a far better value play than Grand Maestro or EVOs for low-end lovers, thanks to cleaner bass and tamer upper mids. For warmer, smoother needs, DUNU’s take is fuller but not as rumble-clean or open. Under $1,000, Titan sets a new benchmark for bass-heads who still want clarity, air, and control.

Youtube Video Summary

Symphonium’s Helios arrives as a four-BA flagship with a spartan unboxing: a solid aluminum, waterproof “hockey-puck” case, multiple tip sets, and a standard 0.78 mm cable. Build is plain but substantial, and the shell is large with a wide nozzle—fit and comfort will be the biggest variable. The stock case’s rough threading and the cable’s lack of ear guides are minor gripes, but the overall presentation feels purposeful rather than flashy.

Tonally, Helios tracks Harman through the low mids, with a sub-bass-focused shelf and almost no mid-bass for maximum cleanliness—bass stays out of the mids and still slams impressively for BA. The midrange is clean and slightly lean (200 Hz dip, relaxed pinna gain) but well balanced. Treble is the showpiece: linear, extended, and airy to the edge of audibility, delivering uncommon “air” for the price. With Azla-style tips that air can verge on abrasive; swapping to the included silicone tips smooths the top end and improves coherence without dulling the sparkle.

Technicalities punch at the front of the kilobuck pack: resolution that hangs with class leaders, incisive imaging with uncanny “backwards” cues, and lively macro/micro-dynamics that give transients real snap. It may trail ultra-high-end sets by a hair in bass texture, but overall performance is compelling enough to edge out many peers. Verdict: an easy recommendation on sound alone, with the caveat to demo for fit—the shell size and nozzle girth will decide whether this brightest kilobuck star truly shines for you.

Youtube Video Summary

Symphonium Titan shows up with a big box, a blue theme, and a cable that feels too soft for a $1,000 set, plus a hefty metal case that could double as a tiny sarcophagus. The shell styling reads plain, almost like a stickered faceplate, and the accessory pile is fine-but-forgettable. The headline spec, though, is the eyebrow-raising 3Ω impedance—a choice that can stress amps, make cable impedance matter far more than it should, and generally feels needlessly risky when series/parallel options and crossover tweaks exist. Swapping cables doesn’t fundamentally rescue it; the blue stock wire is comfy but uninspiring in hand, and tip-rolling doesn’t unlock anything magical.

Sonically, Titan delivers a tidy, punchy kick drum and then coasts. It comes across as an all-BA tuning that’s overly polite: narrow soundstage, very neutral demeanor, vocals that sedate rather than seduce, and detail that never reaches “crystalline.” The sensation is like a go-kart with a limiter—foot down, waiting for excitement that never arrives—leaving the set short on engagement or a defining “thing” that justifies the price. Across amps—tube pre, solid-state, speaker-ish outputs—the character stays the same: controlled bass thump surrounded by music that refuses to wake up. In a world where a $21 budget set can spark a grin, Titan’s ultra-safe tuning and 3Ω quirk make it more “why?” than “wow.”
