Youtube Video Summary
Letshuoer x HBB’s Kinda Lava retunes the EJ07M toward a neutral-with-tasteful-bass-boost signature, thickening the mid-bass versus the original’s Harman-leaning sub-bass shelf. The midrange sits essentially dead-on neutral with excellent clarity and micro-contrast, while the treble is well-extended yet notably safe for sibilance, occasionally showing a soft, sandy EST texture. Versus the stock EJ07M, this tuning feels more integrated and less “subwoofery,” though overall differences remain subtle.
The headline is the bass quality: firm attack, clean decay and addictive depth—easily among the top tier in the price class—without bleeding into the mids. Technicalities are solid, with decent imaging, but the head-stage runs a bit narrow and the overall tilt can sound slightly dark on airy recordings. Build is light metal with red shells and a handsome screw-top metal case; the stock cable feels basic for the price and the faceplate finish looks less premium than expected.
Fit is comfortable but may need SpinFit CP100 tips or a taller two-pin cable to lock in seal and stability. In comparisons, Sennheiser IE600 hits harder up top with a V-shaped incisiveness and wider sense of space, while Moondrop S8 offers brighter openness and BA-clean mids but less bass body. Kinda Lava threads the middle with balanced tonality, safe/detail-rich treble, and outstanding bass, culminating in a confident 5/5 verdict for listeners prioritizing natural mids and elite low-end over max soundstage.

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.

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.

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.
