World-class bass with incredible depth and dynamics. Held back by a slightly unrefined treble response.
Youtube Video Summary

Brise Audio Fugaku stands out immediately for its bass: incredibly deep, dynamic, and explosive, with attacks that feel like notes appear from thin air and a tight, non-lingering decay. It’s the kind of presentation that can be called best-in-class bass for any IEM, a must-hear experience even if the overall package doesn’t justify its $16,000 price tag.

Beyond the low end, the tuning falls into a Harman-esque mold—a clean midrange with a 3 kHz pinna region and a slightly elevated 3–5 kHz—while the treble carries extra energy, especially past 15 kHz. Those highs arrive with multiple distinct peaks that aren’t the most refined; they can overlap and create auditory masking, subtly shaving perceived micro-detail. In short: a technically solid, relatively conventional mid/treble wrapped around an absolutely world-class bass that steals the show.

Technical excellence (accuracy). Near perfect tuning. Bass...great Price. Wait.
Youtube Video Summary

Subtonic STORM lands as a $5,200 flagship built around novel SLAM balanced-armature tech: the dual BA “subwoofer” and “woofer” are separated and crossed over independently, joined by a regular BA mid-woofer, additional BA mids, BA mid-tweeter and tweeter, plus two ESTnine drivers total with a seven-point crossover. The result isn’t just another spec sheet; it’s a system that behaves like a rethought low-end engine that sets up everything above it.

On music, the bass ranks an honest 8/10 because it doesn’t sound like typical BA bass—there’s real weight without mid bleed, so male/female vocals, strings, and guitars stay pristine. Complex tracks reveal studio fingerprints: the 38 Hz triple drop on Big Boi’s “Kill Jill” slams; the glockenspiel in Springsteen’s “Born to Run” is crystal; Pink Floyd’s “On the Run” left-right sweeps and the early gate announcement snap into focus; Hendrix’s uneven production becomes obvious; and the Led Zeppelin IV kick-drum intro hits with the produced, swirling authority it should. From Vivaldi to hip-hop, it just handles the library.

Stage is spacious and speaker-like off good sources, with positional cues that outclass sets like Elysian Annihilator and even edge the Fatfreq Grand Maestro for resolution, stage, and tonality—though Grand Maestro’s multi-tuning keeps it competitive. Ignore treble “hacksaw” graph takes and target-chasing; the performance argues against strict adherence to Harman-style curves. Diminishing returns are real, but for those chasing something genuinely different, the STORM’s reworked BA low end and refined EST top end deliver a uniquely authoritative, all-genre presentation that’s hard to unhear.

The Subtonic Storm delivers a balanced sound signature characterized by a generous sub-bass boost, neutral midrange, and an elevated, articulate treble response. Its standout feature is the implementation of proprietary SLAM drivers—custom balanced armatures handling separate sub-bass and mid-bass frequencies—which produce exceptional slam and texture rivaling dynamic drivers. The treble exhibits deliberate, controlled peaks between 5-15kHz, contributing to vividness without harshness, though some listeners may note a slight roll-off past 16kHz.

Technically, the Storm sets a high bar with class-leading dynamics, micro-detail resolution, and driver coherence across its hybrid array. Staging offers strong width and depth but lacks a cohesive center image. Ergonomically, the titanium shells are bulky and heavy, causing fatigue during extended use, and the stock cable is often criticized for stiffness. Additionally, its low sensitivity demands powerful amplification, limiting portability.

The Brise Audio Fugaku represents a radical departure from conventional IEM design, functioning as an integrated portable audio system rather than standalone earphones. Its core innovation lies in relocating the entire active crossover network to an external dedicated amplifier, bypassing traditional passive filters housed within earpieces. This architecture enables direct driver amplification via a proprietary 7-pin cable and multi-amp configuration, theoretically minimizing signal degradation and distortion.

Sonically, the system delivers an expansive, speaker-like presentation with exceptional micro-detail retrieval and separation, particularly in vocals and treble regions. The tuning leans neutral-bright with a gentle W-shape, featuring controlled bass that extends deeply without overwhelming midrange clarity. However, its extreme resolution and transient speed can create listener fatigue during extended sessions, while the proprietary ecosystem limits compatibility with third-party sources or cables.

Practical compromises emerge in portability due to the mandatory amplifier and dual-device stack (DAP + amp), alongside a six-hour battery life that necessitates frequent charging. The titanium earpieces offer secure fit via integrated TPE ear hooks, but the non-standard cable termination eliminates aftermarket cable options. While the system achieves remarkable technical performance, its astronomical price positions it as a niche solution for uncompromising enthusiasts willing to trade convenience for fidelity.

The best IEM I've ever heard. Best timbre. Super natural. TOTL tech. It's just good. That's all.
Youtube Video Summary

Most IEMs inevitably introduce flaws that shatter musical immersion—be it harsh treble, shouty vocals, or unbalanced bass. These imperfections act as chains, binding the listener and preventing that elusive state of pure, uninterrupted freedom within the music. While the OG EJ07 came close, even it faltered on certain tracks, its forward vocals becoming a jarring distraction when pushed hard. The Subtonic Storm, however, shatters this pattern entirely.

Contrary to its name, the Storm represents the eye of the hurricane—a sanctuary of pure, effortless sound. It liberates the music from tuning flaws, presenting it naturally and tranquilly. There are zero distractions or attachments holding the listener back, enabling deep introspection and complete immersion, as if conversing directly with the singer or instrument. This profound, intangible quality—achieving that free state—is why it's considered the best IEM, offering unmatched resolution, separation, and imaging, albeit at an astronomical $5,000 price point.

Value-wise, the Storm is undeniably terrible; the KZ ASF ($250) gets you 80% there, and the Monarch MKII ($1,000) delivers 95%. It's a luxury item, justified only by its unique, unmeasurable ability to dissolve worldly distractions and forge total oneness with the music. Crucially, it's not for everyone: Bass heads, background listeners, or those enjoying J-pop/K-pop/EDM will find far better value elsewhere under $300. Only those deeply seeking musical transcendence, with ample disposable income, should even consider it. For everyone else, stay away—you simply don’t need it.

Neutral: Staging is intentionally different to traditional IEMs and has forward projection. Can be pro or con depending on preference and genre, but makes any "real" music far more real than other IEMs, whereas "artificial" music can be relatively less impressive. Tonal perfection, technically unmatched, other high end IEMs may compete in some aspects, but never all at once. The single best available and works as an all-rounder. Requires tremendous amount of source gear investment to perfect it, low availability, and makes the whole system expensive and less convenient.
Youtube Video Summary

Subtonic STORM arrives as a spectacle: a limited run of 50 units presented in a hefty suitcase-style box that feels close to 2 kg. The unboxing greets with a personalized card and serialized plate—in this case marked “STORM 019.” Accessories are equally premium: a neatly organized tip case and a Singaporean handmade leather pouch crafted from aged Italian leather, signaling boutique attention to detail before the earphones even leave the case.

The earpieces show off a golden “stormy” faceplate evoking mythic cloud imagery, backed by hand-enameled black paint so meticulous that one in three plates is discarded to meet quality standards. Even the stock cable is positioned as ultra-high end, quoted at around $2,500 with an intricate crystal-lattice design. Price is acknowledged as “way too much money”, yet the presentation unabashedly stakes a claim as the world’s best IEM. This video stays focused on the unboxing and build; a full listening review is teased for a later date.

The most extraodinary normal sounding IEM ever. Amazing all-around big and heavy shell
Youtube Video Summary

Subtonic STORM closes the list as the ultra-high-end, “one-and-done” pick—the kind of most expensive flagship that needs no hype because the name says it all. Chosen for a “versatile” roundup, it’s framed as the endgame option for those who want a single IEM to cover everything and have the budget to match—cue the playful “rich boys” jab.

The verdict is equal parts praise and pragmatism: demo first. STORM isn’t a blind-buy, and the price is so stratospheric it gets the tongue-in-cheek advice to sell a car, a house, or a kidney. In short, a summit-fi statement piece with serious one-set potential—but only after making sure the tuning truly clicks.

Fugaku is a MEMS-powered IEM that wears its identity loud and clear: air—tons of it. The moment you hit play, you’re greeted by an open, shimmering atmosphere that screams treble authority. Measurements confirm a massive 15 kHz peak and another around 19 kHz, pushing extension nearly flat to 20 kHz. That’s MEMS magic—scary good, if slightly intimidating.

Tonally, Fugaku isn’t shy about its tuning. Vocals sit forward with a sweet, honeyed coloration—lush, expressive, and a little nostalgic. The upper mids peak just before 3 kHz, lending intimacy without aggression. It’s not “neutral” in the textbook sense; it’s flavored naturalness—an idealized realism that flatters everything from anime soundtracks to ballads. Think silky textures, warm hues, and that addictive “anime glow” of human tone—beautiful, not clinical.

Bass tilts warm and generous, led by a lifted upper-bass shelf that surpasses even JM1’s +8 dB Bass rise. It’s rich, cozy, and wraps the mix in warmth. Punch lands cleanly, though sub-bass depth depends on the source—Linn Selekt brings satisfying rumble, while leaner amps like Covert-2 sound clearer. The warmth bleeds tastefully into the mids, tying the whole presentation together.

Verdict: Fugaku isn’t about neutrality—it’s about immersion. Air for days, syrupy mids, and a weighty warmth that flatters vocals. Demanding on source, yes, but in the right chain, it’s mesmerizing—a MEMS showcase that turns treble brilliance into emotional theater.
