Tonally excellent and technicalities are fantastic. Works as an all-rounder with little to no flaws. Mids could be a little better, BCD effect could be improved on.

Bass thunder, with impedance adapter fun and switches. The 11 is for Z.
Youtube Video Summary

Nightjar Duality presents as a $3,000 dual-dynamic IEM with a focus on premium build and ergonomics: a bespoke shell that seats comfortably, a recessed 2-pin, and user-tunable hardware via onboard switches and an included impedance adapter that can push bass even further. Packaging includes multiple thin, lightweight cables and even a powered dongle option. The craftsmanship feels boutique, and the faceplate aesthetic underscores its luxury positioning.

Tonally, this is a bass-forward set with two personalities: a “normal bass” configuration that retains balance and a “crazy bass” mode that becomes emphatically sub-heavy. Treble carries air and decent detail without chasing a hyper-analytical edge; mids are serviceable but a touch off, responding well to a bit of EQ. Overall dynamics hit hard, staging and clarity remain clean enough for the tuning goal, and the tuning reads as an enjoyable, romantic DD presentation—just not the final word in microdetail at this price.

In context, alternatives frame the value conversation: Grand Maestro is cited for stronger detail/air and driver refinement (though Duality fits better), while options like the Origin, Zen Magrid T Pro (~$500), Effect Audio Quantum, and even the budget Aether planar show that similar or complementary traits exist at lower brackets. Compared with sets such as Scarlet Mini or Maestro Mini, Duality’s bass shelf and presence balance feel more considered. Verdict: a unique, fun bass-head flagship with excellent design and ergonomics; the price is the hurdle, so demoing at events like CanJam is strongly advised before committing.

A good set, but lacks magic for me to justify keeping.
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.

Massive yet controlled bass. Lush timbre and well-extended, non-pesky treble. Bassy mode may be too bassy for some. Mids can be a touch forward on balanced mode.

Resolution and tactile slam with not ultra boosted bass. brilliant tuning. Tactility only shows under extreme bass hits between 50 and 100Hz. Not sure why? Otherwise very oudiophile replay of rhythm section
Youtube Video Summary

Canpur CP622B is positioned as a true apex set among today’s ultra-high-end IEMs—think Storm, Grand Maestro, Pearl, Multiverse, RN6—where differences are subtle and taste-dependent, not about basic quality. The message is simple: once at the Money Trees level, most flagships are excellent; the CP622B stands out by pushing resolution and authenticity to the top of that pile while keeping music the focus.

Evaluation leans on a tight suite of reference cues: bass definition via Black Sabbath “Sweet Leaf” (2:36–3:10), midrange texture with Soundgarden “Spoonman” (spoons/vocals) and Neil Young “The Needle and the Damage Done,” and treble control from Aerosmith “No More No More” (recurring cymbal strikes). Micro-details and spatial tells include Michael Jackson’s beep, Violent Femmes finger snaps, the crowd-side triangulation in Lynyrd Skynyrd’s “Freebird,” Pink Floyd’s gate announcement in “On the Run,” Randy Rhoads’ finger slide in “Dee,” and the famous cough in “Wish You Were Here.” These checkpoints spotlight the CP622B’s clarity, attack/decay, and rare sense of depth for an in-ear.

Two practical notes seal it: level-matched A/B at 77 dB @ 440 Hz versus Subtonic Storm to ensure fair comparison, and a low-frequency test around ~42 Hz that makes the shells physically vibrate, delivering that body-felt slam prized in hip-hop and recognized in orchestral power. With a library spanning ACDC, Alice in Chains, Bob Marley, Dre, Kendrick, Metallica, Pink Floyd and more, CP622B reads as a top-tier all-rounder—immense detail at low volumes, potentially intense when cranked, and an easy recommendation for those chasing the very best.
