64 Audio Nio VS Linsoul x HBB Jupiter

Youtube Video Summary

The 64 Audio Nio enters as the most affordable set in this lineup at $1,700, a hybrid with 1DD + 8BA and swappable apex modules. Its core tonality is warm and a touch laid-back, with the M15 module pushing bass toward “too much of a good thing”—thick, soupy, and less resolving. Swapping to the M10 cleans things up: bass settles closer to neutral, top-end clarity improves, and the presentation feels more balanced overall. Detail is respectable rather than showy, and while the Nio can be bassy, it doesn’t deliver the most controlled low end when boosted. The standout trait here is timbre—the most natural-sounding of the group, especially with M10 installed.

Used as a daily driver, Nio with M10 suits listeners who want a smooth, natural tonality without treble bite; with M15, it veers into warm-thick territory at the cost of separation and perceived detail. Against 64 Audio’s own stable, it doesn’t reach the U12t’s BA bass quality or the Trio’s stage depth, but it offers an easygoing, organic listen that some will prefer on timbre alone. Verdict: 4/5 with the M10 module; drop to 3/5 on the M15 due to excessive bass and haze.

The 64 Audio Nio is a hybrid with 1DD + 8BA that leans into a richer, warmer presentation, trading ultimate microdetail for slam and engagement. Build and comfort are solid with a classy case upgrade; fit can vary, but tip selection helps. Technicals are mixed: imaging and separation are clean, staging is a bit intimate, and treble resolution is good via the TIA driver without sounding sharp.

The headline feature is the swappable apex modules. M15/M20 push the Nio into basshead territory—big sub-bass, head-nodding punch—while MX reins in the low end for a more balanced tonality that suits acoustic, jazz, and classical. Treble is well-extended yet relaxed; with the right tips, the 5 kHz energy avoids harshness, keeping the overall tuning smooth and non-fatiguing.

Against peers, the Nio’s strengths are its dynamics and configurable bass; its weaknesses are detail retrieval and stage size versus benchmarks like the 64 Audio U12t. Listeners chasing maximum clarity and air may prefer U12t, while those wanting hybrid physicality and tunable low-end will find strong value here. Verdict: choose M15/M20 for guilty-pleasure thump, choose MX for balance—the Nio remains a versatile, engaging high-end option.

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.

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.
