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

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.

A 5-BA successor that lands at $700, claims “re-engineered” BA bass, and feels like a welcome throwback to when high-end Chi-Fi wasn’t four figures. Build and fit are excellent with a rock-solid seal; the thick cable behaves well but annoyingly ships 4.4-only with a 3.5 mm pigtail. Tonally it’s essentially neutral up top with a big low-end shelf—treble is clean and non-fatiguing, imaging competent, and the bass is unusually physical for all-BA, though it can be inconsistent (and a bit tubby on bass-heavy mixes) versus a good DD. Net: a supremely competent, do-everything all-rounder that trades “wow” factor for balance—I prefer it over Dunu SA6 Mk II, see Symphonym Meteor and Moondrop S8 as taste-based alternatives, and I land at a solid 4/5.Super* Review original ranking

Softears RSV MK II brings back the all-BA ethos at $700 with five armatures and a promise of “re-engineered BA bass.” Build and accessories feel premium (sleek shells, plush case), while the cable choice is quirky—4.4 mm only with a 3.5 mm pigtail. Fit is outstandingly secure and custom-like but on the larger side with a longer nozzle, so comfort depends on ear size. Softears’ Ultra Clear tips work well; the new metal-ring variant adds little beyond novelty.
On the graph, bass looks like gigabass, yet in ear it settles into a warm, weighty foundation without steamrolling the mids. The midrange follows a “new-meta neutral” tilt—fuller than Harman with forward upper-mids—while treble lands clean and sparkly without fatigue. Imaging is tidy rather than cavernous; separation and delineation are convincing, with the top end executed better than the bottom. BA bass here is among the more physical and satisfying of its kind, though tactility can be track-dependent and turn a bit tubby on very bass-heavy mixes.
Against peers, Symphonium Meteor sounds warmer and more “special” but less all-round; DUNU SA6 MK2 is more colored with janglier treble and the least convincing bass; 7th Acoustics Supernova trades warmth for vivid, bright-tilted imaging; Softears Studio 4 is lighter on bass and airier; and the old Moondrop S8 stays the lively, vocal-centric counterpoint. Net take: a supremely competent, character-light all-rounder that favors bass weight over panoramic staging. Verdict: 4/5 stars—a welcome throwback done right, and notably cheaper than the original RSV launch price.

Bassy dynamic all-rounder with great low-end texture that slams hard with good note-weight/body. Slight Hype 4 upgrade. Treble is smooth, and vocals are well-tuned. Overall unboxing/accesories are great... just no ESTs at its price, I'd wait for sale. Jays Audio Youtube Channel
Softears RSV MK2 shifts from the OG’s vocal-centric tilt into a bass-forward all-rounder. The sub-bass and mid-bass hit with real slam and weight, giving drums and bass guitars a satisfying, dynamic punch. Upper mids (3–6 kHz) are tamed to avoid shout, while a gentle 1–2 kHz rise keeps vocals open and natural—slightly less pushed than the original but still clear. Treble is smooth with decent air; not super sparkly and there’s no EST “sauce,” but it stays clean and non-fatiguing.
As a package, MK2’s standout is the low-end texture—thunderous yet controlled—making it one of the more engaging bassy sets under four figures. Technical performance is solid for the tier, though some rivals at lower prices bring more raw detail and EST extension. Build and accessories get a tasteful, modern refresh. For best balance, the stock tips work well; bass-boosting or treble-opening tips can shift it toward a more V-shape at the expense of overall smoothness.
On genre fit, MK2 shines with hip-hop, pop, EDM, and R&B, where its punch and warmth bring rhythms to life; for orchestral or leaner acoustic picks, the bass can edge forward depending on the mix. It scales to mid–high volumes nicely (around the 70–80 dB zone) without turning sharp. Compared with the OG RSV—now likely affected by a silent retune in recent units—the MK2 is the safer buy: less shout, more authority down low, and a broader all-rounder appeal. Recommended, especially if found below full MSRP, for listeners craving tasteful bass with natural mids and relaxed, smooth treble.

The Softears RSV MK II refines the original RSV with an all-5BA design and a 4-way crossover, targeting a stable “reference sound” while improving driver control and airflow management. It’s easy to drive at 122 dB/Vrms, 7 Ω, and the build mixes medical-grade resin with CNC-milled aluminum and forged carbon for a robust, low-resonance shell; MSRP is $699.
On paper, the tuning remains neutral with a bass lift: dual Knowles CI22955 woofers aim to give BA-bass more texture and weight, an improved ED driver anchors clean mids, and a SWFK unit handles upper treble for a smoother, less fatiguing top end. Softears’ LRC network and dual pressure-relief approach target consistent FR and reduced ear pressure, which should aid long listening sessions and imaging stability.
Subjectively, this positions the RSV MK II as a coherent, midrange-centric set with tight, controlled low-end rather than maximal slam, and a smooth treble that trades sparkle for fatigue-free listening. Soundstage is moderately wide with tidy imaging; technicalities are competitive for the class but won’t chase ultra-etched detail specialists. Given the tuning goals and efficient drive requirements, value will appeal most to listeners prioritizing tonal accuracy and midrange timbre over sheer sub-bass impact or treble air.
