64 Audio Volur VS Eminent Ears Ruby

Youtube Video Summary

The 64 Audio Volür shows up as a $2,500 showpiece: a 10-driver monster with dual dynamic woofers and a pile of balanced armatures, wrapped in a shell that actually looks as expensive as the sticker suggests. Build feels solid and the faceplates are properly flashy, but the stock cable gets called out as nowhere near worthy of the price tag, so an aftermarket wire like the purple PW Audio one on hand feels more fitting. The kit is pure luxury excess: leather case, tip “spider brain” organizer, foams and silicones in every size, and a set of tuning plugs that turn the nozzle end into a tiny science project.

Those tuning plugs are not a gimmick; they meaningfully swing the tonality, especially in bass and treble. Black filters come off as “B for boring,” gold brings extra energy up top that can get too spicy, while gunmetal and silver do the real work, with silver acting as the “bass king” and gunmetal giving a more balanced but still meaty presentation. Once settled on the right tips and plugs, Volür becomes a hyper-revealing, crazy-sensitive in-ear that throws every element of a track into its own little bubble, lining them up on a mental shelf with pinpoint separation, U12t-style microdetail, and surprisingly hard-hitting dynamics that make kick drums and stomps feel almost uncomfortably real.

Despite that level of resolution, Volür doesn’t punish bad recordings as brutally as some ultra-revealing sets; even rough Foo Fighters masters stay enjoyable, just carefully dissected and displayed instead of mashed into a blob. It’s very easy to drive, brutal on noisy chains, but otherwise fairly amp-agnostic: give it a clean source and it simply does its thing, turning almost any track into a forensic listen. From a value perspective, the price is still called stomach-churning—especially after the MSRP hike—but as far as high-end IEMs go, this one absolutely behaves like a “big boy” piece: four tunings in one box, serious bass authority, and a level of detail and separation that sets a benchmark for what expensive in-ears are expected to do.

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.
