Linsoul x HBB Jupiter VS 64 Audio Volur

Youtube Video Summary

Premium build with a large, Monarch-like shell that sits extremely comfortably, accented by subtle blue flecks and a secure nozzle lip. The bundled 4.4mm cable feels upscale, while the case and tips are serviceable. There’s noted pricing controversy—an initial teaser around $1,000 for a handful of units before settling near $1,600—but the product itself presents as a polished, high-value package.

Sonically, this is a strong, impactful bass tuning with rich warmth that never smothers the mids. Female vocals pop, instrumentals sound lifelike, and earlier worries about a dark treble prove overstated; the tonal balance feels right and cohesive. Sub-bass digs deep, mid-bass hits with authority, and the overall presentation is sweet, engaging, and musical—the sort of set that invites long sessions without fatigue. It comes across as a top-tier collaboration with a crowd-pleasing signature for bass lovers who still care about clarity and timbre.

In comparisons, Dunu’s Mirai reads brighter and leaner with issues like hiss and channel imbalance on the sample heard, scoring around “three stars,” while Jupiter earns a decisive “five-star” nod. Against heavy hitters like Elysian Annihilator and Grand Maestro, those sets feel more resolute, but Jupiter is more fun, with a richer, sweeter tonality. Versus Fatfreq Scarlet Mini, Jupiter offers just-right bass (rolling off warmth around ~200 Hz) rather than excess. The conclusion is emphatic: a 9.04/10, described as a “love letter” to bassheads and one of the finest pure basshead tunings heard—highly recommended, especially if a second-hand deal brings the price closer to earth.

64 Audio Volür comes across as a tour-de-force of bass tech: dual true isobaric dynamic drivers deliver deep, textured rumble with a “speaker-in-the-room” feel, while the Tia BA adds pronounced upper-treble energy. Ergonomics are excellent—compact metal shells, smooth nozzles that take tips well, and a best-in-class top two-pin connection that makes cable swaps effortless. Build feels built-to-last and the purple faceplate looks classy, though a more varied aesthetic across 64 Audio’s lineup would be welcome.

The APEX modules change flavor more than fundamentals: M20 adds a touch more bass, M15 strikes the best balance, M12 runs leaner, and MX is very flat and generally skippable; running it empty is a hard no. On music, Volür shines with EDM/modern productions, projecting holographic low-end and vivid dynamics; in dense mixes with strong instrumentals and vocals, the midrange can feel overrun and less engaging. Versus peers: U4s tracks similarly in bass level (with different modules), Elysian Annihilator brings stronger 3 kHz vocal presence while Volür counters with superior bass texture, and Monarch MKIII sounds more overtly U-shaped with greater mid/upper energy.

As a package, this is a fantastic IEM—arguably a favorite from 64 Audio—yet not flawless. The price is steep, the APEX ecosystem feels like paid tuning switches, and there’s some treble peaking plus occasional vocal thinness; a simpler, cheaper, M12-style fixed tuning would be a dream. For listeners prioritizing hip-hop, rap, and modern genres, Volür can absolutely be endgame; for vocal-centric or classical libraries, it’s impressive but not definitive. Overall verdict: a five-star recommendation for those who can afford it, anchored by class-leading bass and exceptional build, with clear trade-offs noted.

Youtube Video Summary

Linsoul x HBB Jupiter aims straight for flagship territory: a warm-tilted, slam-capable set that keeps the mid-bass → mids transition impeccably tidy. There’s real shove at 55 Hz and healthy weight around 100 Hz, but from ~200–300 Hz the response dips with intent, avoiding bleed and preserving vocal clarity. The result is a low end that thunders on hip-hop and classic rock kick drums while keeping male vocals husky but clean and female vocals free of mud. Upper mids and treble track more like Helios SE, Subtonic Storm, “the Bird,” Letshuoer Cadenza, and “Dawn” than like shoutier sets; energy near 5 kHz is moderated, and sparkle up around 12 kHz stays present without spike.

Hardware backs the tuning: an 11-driver array with 4 EST, a dynamic for the heavy lifting, and BAs smoothing the handoff into the mids. That division of labor helps with resolution and separation—handling tricky passages (distorted guitars, busy bass+kick overlaps) with composure and less masking than many DD-centric rivals. The overall presentation reads as warm, punchy, and refined: more bass authority than the comparison set list, mids that sit centered rather than in-your-face, and treble detail that reveals micro-stuff without tipping into fatigue.

Build and accessories match the premium pitch, including the beloved (and pricey) Linsoul Loops cable that visually suits the green/gold shells. Pricing is high, yet the claim is that it outperforms peers that cost similar or more by marrying sub-bass power to disciplined midrange and tasteful air. For listeners whose libraries span hip-hop, rock, R&B, and even classical, Jupiter reads as a statement piece: big-boy bass, clean mid articulation, and high-tier treble finesse—tuned to deliver musical weight without sacrificing balance.

Youtube Video Summary

64 Audio’s Volür is described as a holographic, highly resolving IEM with unusually high bass quantity that still preserves separation, layering, and air between notes. In games, positional cues feel 3D with immaculate depth and verticality; footsteps are prominent without smearing the mix, and vocals remain transparent with accurate timbre. The upper range presents as clean and non-sibilant, though certain upper-mid effects (e.g., shield cells/light taps) could use a touch more presence. For music, the stage is wider with singers a bit farther out, and micro-details—breaths, mic proximity, subtle slurs—emerge easily, delivering a fun yet technical listen.

Hardware choices matter: the preferred module is the gray (then silver, gold, and lastly black, which can feel fatiguing). Tip rolling significantly alters the presentation; foam tips shift it the most, while alternatives like Snailfit/SpinFit change stage depth and comfort. The driver pack—dual dynamic drivers in a true isobaric low end, six BAs for mids, an extra BA up top, plus 64 Audio’s TIA—underpins the speed, texture, and punch that remain controlled even at elevated bass levels. The main gripe is the included 3.5 mm cable on a flagship at this price; a balanced 4.4 mm option in the box would better fit expectations.

Overall, Volür is framed as an S-tier “unicorn” for gaming and a top-shelf choice for music if a bass-boosted but impeccably separated signature is the goal. It’s expensive, but for those in this bracket, the combination of impact, imaging, and resolution makes it a compelling daily driver—powerfully engaging while staying precise across the range.

Youtube Video Summary

64 Audio’s Volür brings a bold, U-shaped tuning powered by a 10-driver array (8 BA + 2 DD in an isobaric setup) at a premium $2,500 price. The headline is the bass: a meaty, wallopy low end with unusually tight, textured attack that hits hard yet stays controlled, preserving clarity through the mids. Upper mids sit a touch relaxed, while an upper-treble zing adds bite, separation, and a roomy stage. 64 Audio’s APEX modules (M10/M12/M15/M20) primarily shift bass quantity; counterintuitively, the set shines most with the M20, where elevated bass balances the treble sparkle.

Build and ergonomics mirror recent 64 Audio releases: medium-sized shells with a slightly long nozzle (comfortable overall but fit stability can be just okay), plus a decent if slightly kinky stock cable. Technically, imaging, separation, and stage feel contrast-rich and more convincing than many peers. Tone preferences will matter: reduce the bass with lighter modules and the treble can dominate; leave the bass up and the presentation becomes satisfyingly muscular without smearing. As a proposition, Volür suits bass enthusiasts who want quantity and quality in tandem, earning a solid 4/5 for delivering big low-end thrills with high-end technical finesse.
