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
Lime Ears Maris is a flagship 12-driver quad-brid with branded components, combining multiple BAs for lows/mids, dual Sonion ESTs for air, and a dual Sonion bone conductor for full-range weight. At $2,700 (“Ensemble”), it brings a thin-walled but comfortably large shell, flat 2-pin sockets, and an excellent leather puck case; build and fit feel deliberately premium, with only a minor faceplate edge that can snag. Overall presentation and ergonomics signal a top-tier, tour-worthy piece.
Sonically it’s a fun, impactful tuning: bass hits hard with tactile BC rumble, treble/air are pristine, and resolution is high with an open, spacious stage. The upper-mids are slightly restrained (a touch of ~4 kHz dip) which softens attack—less “incisive” than the graph might suggest—but the set remains clean, coherent, and easy to listen to for treble-sensitive listeners. Think “inoffensive but exceptional”: refined energy up top, big physical slam down low, and clarity that holds together complex mixes.
Context against peers: Terra is exciting but the 5–6 kHz energy can fatigue; Incognita tracks a preferred curve better as a one-and-done at a lower price. Annihilator offers more bite in upper-mids/treble, yet Maris will suit those sensitive to that region; versus Grand Maestro, Maris wins on comfort and bass quality. Compared with Europa, Cadenza 12, Omnium, and Visioner’s 10, trade-offs shift—some deliver sharper treble “spark” or smaller shells—but the Maris’s bone-conducted bass, comfort, and safe-refined balance make it a strong recommend to demo at a show before choosing.
