Aroma Audio Fei Wan VS Canpur CP622B

Youtube Video Summary

Aroma Audio Fei Wan goes for broke with a dual-dynamic + 10BA hybrid and a sticker price around $4,688. The build is striking: a clear yellow shell with visible drivers and a glossy faceplate flecked with gold, though the shell runs large. The stock 2-pin cable is functional but a bit tangle-prone; the retro-styled unboxing and case feel premium. Minor quirks include occasional driver flex on insertion. Overall fit is comfortable despite the size, and the presentation screams boutique.

Sonically this IEM is all about texture, extension, and microdetail. Bass reaches deep with layered rumble rather than brute “slam,” mids are clean with slightly recessed vocals, and treble delivers air and sparkle without poking the 4–6 kHz zone. The graph shows healthy ear-gain and notable bass, but the magic is off-graph: resolution and overtones that feel world-class. Compared with benchmarks, Elysian Annihilator 2023 still wins on tone and vocal focus, while Fatfreq Grand Maestro and others share the “big-boy IEM” experimental flavor. Sets with shout or odd presence peaks (e.g., Dream XLS, E10/E12, Bonneville) don’t fare as well. EQ can nudge tone a touch “better,” but also trims some of Fei Wan’s special sauce—net maybe a 1–2% improvement.

Verdict: a special, statement-level IEM with second-to-none technicalities, deep textured bass, and elegant treble—tempered by a sky-high price and mids that could use more sparkle for vocal diehards. It slots just below Annihilator overall, earns a guarded recommendation, and absolutely warrants a demo before purchase. For value-minded listeners, options like Letshuoer Hype 10 capture a similar neutral-with-weight idea at a fraction of the cost, while many S–/A-tier picks remain safer bets for most.

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.
