Youtube Video Summary
Hisenior Mega5-EST +Bass comes as a custom set with personalized shells and a straightforward Pelican-style case. The build is compact and comfortable with an easy tip-lip, though the color matching can look inconsistent in certain light and the stock cable feels a bit lackluster—thin, slightly stiff, and not as plush as expected at this tier.
Sonically, this is where it clicks: a tasteful bass shelf for proper foundation, pristine upper-mids for clarity, and airy EST extension that brings out detail without harshness. It tracks close to a personal target shaped by sets like the Elysian Annihilator and JM1—cleaner and more engaging than the stock Mega5-EST, which can feel like “clean water” to some. Comparisons paint the path here: the affordable Hexa shows the right upper-mid behavior; the Chopin is a fun benchmark under $200 with small quirks; Hype 4 offers a Mega-style tuning on a budget but with less bass; and Binary Dynaquattro scratches a V-shaped itch while being harder to drive. Mega5-EST +Bass blends these lessons into a punchy, articulate, and well-imaged presentation.
Value is strong for a custom with EST drivers under a grand—excellent channel matching, convincing technicalities, and a tuning that feels “just right” for modern music without turning strident. Caveats: the order process can be slow (think weeks) and communication runs through Hisenior/Facebook, so patience helps. Not the only answer at the price, but as a preference-targeted custom that adds the missing low-end weight to the original Mega5-EST’s clarity, this one earns an unapologetic S-tier.

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.

Youtube Video Summary
The Hisenior Mega5-EST +Bass tweaks a proven formula with a flashier shell, a softer puck case in place of the Pelican box, and a thick-but-nice stock cable. The most eyebrow-raising extra is a 3.5→4.4 mm adapter that converts single-ended to balanced—an unusual direction that invites skepticism, even if the brand says it’s safe. Fit remains compact and comfortable with a medium nozzle and semi-custom contour; stock tips are serviceable, though shorter tips like SpinFit can improve seal for some. Aesthetically, the red-black motif reads a bit gaudy, but ergonomics and accessory quality are solid overall.
From ~300 Hz up the tuning mirrors the original Mega5-EST: a gently warm midrange, clean upper-mids, and neutral, well-behaved treble that avoids glare while keeping definition. The change is all down low: roughly a +5 dB bass boost that tilts upward from the lower mids rather than living purely in sub-bass. The result is hefty slam that doesn’t completely smear the picture, but it does shave away some micro-contrast and vocal texture; on bass-forward tracks the low end can turn a touch droning and distracting. Still, transient attack up top stays crisp, and the overall presentation remains coherent—just decidedly bass-first.
Versus the standard Mega5-EST, this edition trades nuance for weight; those who wanted “Mega5-EST, but more bass” get exactly that without wrecking the top end. Compared to a purpose-built warm set like the Symphonium Meteor, the Hisenior’s low end feels less integrated and less intentionally voiced, while Meteor’s treble has a bit of special sauce. Verdict: a 3/5—easy to enjoy and well-tuned above the bass shelf, but the extra low-end doesn’t feel necessary and slightly blunts what made the original so delicate and engaging.

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
Hisenior’s Mega5-EST +Bass takes the acclaimed Mega5 recipe and dials in a tasteful bass boost without upsetting the balance. The unboxing screams premium: a plush sheepskin Manta case, a chunky 4.4 mm Manta cable (nicely built, but heavy), shirt clip, multiple tips, and replaceable nozzle filters for longevity. The resin shells with metal nozzles feel sturdy and look flashy—mismatched shells add flair—while the semi-custom shape fits securely for most, though smaller ears may struggle with the shell size and nozzle girth. On paper it’s a tribrid (1DD + 2BA + 2EST), 24 Ω and >100 dB, so easy to drive; note that higher output impedance or a 15 Ω adapter tilts the FR warmer and bassier, turning it from warm-neutral into near basshead territory.
Sonically, this is bass-boosted neutral done right: sub-bass has real rumble, mid-bass hits with authority yet stays tight. The midrange is the star—rich and full without bloom, giving weight to male vocals while keeping female vocals smooth and clean; separation makes dense mixes effortless. Treble from the ESTs is airy and non-fatiguing, with “Goldilocks” sparkle that lets cymbals and harmonics pop without glare. Technical chops impress: fine detail retrieval, stable stereo separation, and a convincing 3D soundstage that places instruments with confidence—competitive with strong mid-fi performers and nibbling at the heels of pricier flagships.
In A/Bs, think of it as the “luxury performance” take on Kiwi Ears K4 (similar balance but smoother, more detailed, and punchier), richer and bassier than the Dunu x Gizaudio DaVinci (which pushes vocals a bit more), and far more all-rounder than the Kiwi Ears x HBB Punch (a true basshead set). The KZ EDC Pro echoes the general contour at a budget, but the Mega5-EST +Bass crushes it in refinement, texture, and resolution—as it should at $590. Value isn’t its calling card, but as a limited edition built on 2024’s crowd-favorite tuning—now with extra low-end fun and a killer accessory pack—this comfortably sits in the “this is brilliant” tier for anyone seeking a bass-tilted meta tuning that still nails mids, treble smoothness, and day-to-day listenability.

Youtube Video Summary
Hisenior Mega5-EST +Bass takes the already clean, wide, crisp Mega5 tuning and pours a thick, buttery layer of low-end over it—think “Eris-sized” weight without muddying the mids. On bass-light tracks, the presentation stays tidy and balanced; when a track calls for slam, the sub-bass turns the room into a vibrating wooden shack (in a good way). The core technicalities—clarity, stage, and treble finesse—stick around, now backed by a warmer, more physical foundation that makes music feel more alive. For listeners who believe most gear is starving the soul of the music, this tuning argues for more bass normalization, not less.
Build and accessories are generous: a stylish case, multiple tip sets, spare filters, cloth, and a quality 2-pin cable. There’s a fit quirk—the nozzles feel a touch long, often sealing best when backed out slightly—but once seated, it’s rock solid. Big warning, though: skip any 4.4-to-3.5 “illegal” adapters and just choose the right termination up front; the balanced option is the move. Under the hood it’s a 1DD + 2BA + 2EST hybrid that clearly cranks the dynamic driver for that plush sub-bass shelf while keeping vocals articulate and highs smooth.
At $589 (vs. the original’s $549), the upcharge buys the “Bass+” ethos done properly: warmth, weight, and fun without trashing detail. It’s the kind of tuning that encourages long sessions and guilty grins—less about clinical reference curves, more about musical gravity. Call it a price-tag score of “589”: not a penny less than it sounds.

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.
