Kiwi Ears Septet VS TANCHJIM x Effect Audio Force

Youtube Video Summary

The Kiwi Ears Septet is a multi-driver oddball in the best way: a single DD + 4BA + planar + PZT hybrid with an open-back shell at $259. Build is solid with a metal body, flat 2-pin sockets and a handsome modular cable; fit is stable and isolation would be strong if it weren’t vented. It’s clearly aimed at listeners who want something different in both design and presentation.

Sonically it’s a down-tilted, slightly L-shaped tuning: deep, thumpy bass, subdued upper-mids, and a sparkly 4–6 kHz region that adds air and detail. The open structure creates a speaker-like stage—wide, clean imaging with a sense of room—but it can show a hint of hiss and benefits from more power (dongle/DAP recommended) to wake up dynamics. It’s a unique, spacious listen that some will love and others won’t; while the treble and imaging impress and it earns a recommendation (even a spot in a price-tier top 10), those wanting stronger presence in vocals may prefer Kiwi Ears’ more conventional tunings or adjacent sets like Astral or Performer series.

Youtube Video Summary

Kiwi Ears Septet lands as an airy, spacious, and distinctly sparkly listen with a clear bright-leaning tilt that avoids harshness. Despite a notable 5–8 kHz lift, the treble comes across refined rather than peaky, while a touch of mid-bass warmth keeps the tonality musical and natural. The result is punchy drums and momentum on rock and acoustic tracks, with technicals that punch above price—layering and separation sit around Dusk/Pilgrim territory. It’s like a more airy, sparklier Meta with less forward vocals and less artificial sheen than ultra-bright sets. The “open-back” faceplate doesn’t audibly change things, but staging still feels wide.

Fit and setup matter: a deep seal smooths treble; tips like Softears Alpha Clear or Tangzu Sancai can tame peaks. The Septet scales nicely on slower tracks up to ~80 dB, but on energetic K-pop/J-pop/hip-hop it can turn hot—hi-hats may sting if the volume creeps. Comfort is solid at mid volume for hours, though sensitive ears may feel fatigue over long sessions, especially in that 5–8 kHz zone. Vocals are set back: clean and inoffensive rather than shouty, but on busy rock they can feel a touch distant. This is a treble-forward, technical presentation; not a mid-centric vocal specialist and not a bass-head set—low end is adequate but softer in impact and pushed slightly to the back.

Versus peers: Astral is the safer all-rounder with more forward vocals and less brightness; Quintet is the vocal-oriented pick, while Septet is smoother, airier, and a bit more micro-detailed. Recent Orchestra Light (unit-dependent) sounds more V-shaped and shouty; Septet takes tuning and technicals. Odyssey wins on immersion, bass texture, and vocal pop at loud volumes, but Septet brings better air, separation, and detail at normal levels. Compared with Lush, Septet is brighter and more resolving; Lush is smoother and one of the best scalers under $300 if you like it loud. For vocals first, look to EPZ P50, Cadenza 4, or Tanjim Origin; for bassier fun under $300, consider DSKO, Estrella, Deuce, or Tros. If a sparkly, airy, technical flavor that stands apart from “Harman-by-default” is appealing, Septet is a worthwhile add to the collection.
