Youtube Video Summary

The Softears RSV MK II is a 5BA set at $699 with a sleek, performance-driven look—carbon-fiber “V” and RS badge on the faceplate—paired to an ergonomic shell and fish-mouth nozzle that stays light and exceptionally comfortable over long sessions. The package is solid: a braided 4.4 cable (plus a 3.5 mm dongle), cleaning cloth, two pouches, and two sets of silicone tips; the only nitpick is wishing for a more premium carrying case at this price.

What sets RSV MK II apart is how a generous bass boost/extension coexists with top-tier imaging, separation, and layering. In Valorant, footsteps hit with extra energy and impact yet subtle cues—water steps, micro-movements—cut through even during Vandal spam and 5v5 ability chaos. In Battlefield the set is a standout for immersion (planes, tanks) while preserving precise gunfire placement and the light “clinks” that win fights. The latest mix in Apex plays to its strengths: thermites don’t mask light taps, elevation cues remain clear, slides and shield pops are easy to track; and in Call of Duty, airstrikes and mortar fire don’t swamp critical information. It’s scored as the lowest-priced S-tier on the WallHack-certified list—note the tonality skews a touch dark, so strict reference seekers may prefer something lighter, but for impactful low-end plus elite competitive clarity, RSV MK II is a killer pick.

Youtube Video Summary

Softears RSV MK2 takes the original’s idea and pushes it into a bolder, bass-centric direction. The compact shell is comfortably contoured, isolates well, and uses a slightly recessed 2-pin; the angular faceplate gives off an “evil Voltron” vibe in the best way. Packaging and accessories feel premium—a silky cable terminated in 4.4 mm with a matching 3.5 mm adapter, tip selection, cleaning tools—though the bundled case looks nice while feeling a bit faux-leather and questionable for durability. Under the hood is a 5-BA array around the ~$700 mark, presented with the fit and finish expected at this tier.

The tuning is unabashedly bass-heavy with a warmer rise through ~150–200 Hz and a slightly dark-leaning top end; not super airy, but undeniably full, rich, and musical. That weight can introduce occasional roughness/sibilance in certain vocals and can muddy spoken-word content, so this isn’t for everyone. Within Softears’ catalog it stands out: far more low-end than RSV (OG), Volume S, Twilight or Studio 4, and a different philosophy than Enigma’s vivid upper-mids. Versus sets like Monarch MK4, this goes for a deeper, thumpier shelf with a gentler upper air—trading a bit of “technical” sheen for tonal density and groove.

As a “tactfully executed bass-head” Softears, RSV MK2 delivers: impactful low end, natural mids, comfortable build, and a coherent, down-sloping balance that suits modern music exceptionally well. It isn’t flawless—moments of aggressiveness, plus a case that feels more pretty than tough—but the overall package is compelling. In the $400–$900 bracket it scores a 9.4 on this scale, while strong lower-priced options (e.g., bass-shelf specialists like Punch-tuned sets) may satisfy similar cravings if budget leads. For listeners craving a plush, powerful low end done with intent, this is a distinctive and deeply enjoyable take from Softears.

Super* Review 8* * score rescaled + normalized
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.
Youtube Video Summary

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.
Youtube Video Summary

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 RSV MK2 still follows Softears’ signature approach: an all-BA design, specifically, five-BA configuration. The “V” stands for both its five-driver layout and its bold carbon-fiber faceplate design.

On the graph, it diverges from JM-1 or Harman, choosing its own path. Sub-200 Hz is elevated, giving the bass notable weight and warmth, but also risking congestion. A dip between 200–600 Hz thins mids and robs some body from vocals and instruments, though it does clean up edges. Then comes a surprising 14 kHz BA-driven peak, adding air, shimmer, and openness—rare for an all-BA set!

In practice, bass hits with real presence for BA, punchy and convincing though not as deep as DD. Mids lean slightly thin, a bit lack of density, making instruments less woody. Treble is airy and crisp thanks to that 14k lift, but may edge bright for sensitive listeners. Stage favors forward bass and a sense of openness, though not massive in depth.

Verdict: It’s bassy, airy, and a touch thin in the middle—a distinct tuning philosophy that stands apart from the crowd.

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.
