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
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
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
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.
