Decent bass and lush, "wet" mids. Has a treble peak that can be pesky to some. Great overall techs. Cons: Price, treble peak, build quality.

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.

Impressive tech, is even better with EQ. Has a special sauce.
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.

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.
