64 Audio Volur VS Canpur CP622B

Youtube Video Summary

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

Canpur CP622B makes a striking first impression with a premium case, tidy accessories, and a shimmering faceplate—but the shell is huge, bordering on chunky, and can push fit comfort limits over longer sessions. Sonically, it hits with authoritative sub-bass and impressive extension, yet the overall presentation skews dark; vocals sit a touch recessed, with a wish for more 1.5–3 kHz presence and a bit more upper-air sparkle. Out of the box it already thumps, but a light EQ lift to upper mids and bass can coax out more vibration and energy.

On graphs and in A/Bs, the CP622B comes off as a specialist: fantastic low-end texture (bass judged around 9.5 for level), solid resolution and stage, but imaging feels slightly constrained by the muted 3 kHz region. Compared with peers, FATfreq Grand Maestro reads like the safer “one-and-done” all-rounder with more flair up top; Aful Cantor delivers comparable presence at a fraction of the cost; Hisenior Mega5-EST Bass offers a friendlier fit and a tuning that can feel just a hair more balanced; and as a personal north star, Elysian Annihilator 2023 still sets the bar for extension and excitement. Net: a fantastically built, bass-thrilling CP622B that shines with hip-hop/R&B and cinematic lows, but reads as niche and pricey—a connoisseur’s piece for big collections rather than a first-pick endgame.
