FiiO FX17
Approved coverage paints the FX17 as FiiO’s statement tribrid: highly revealing, spacious, and technically ambitious, but still tuned to keep its EST-heavy top end musical rather than sterile. Headfonics praises its transparency, layering, and expansive, tightly focused staging, while broader Headphonesty coverage on the driver-count arms race treats the FX17 as proof that complexity only works when execution stays coherent. Early Reddit discussion echoes the same talking points around grand stage, natural sound, and airy treble. The tradeoff is clear too: it is expensive, physically substantial, and aimed at listeners who want flagship detail and scale more than forgiving warmth.
Letshuoer Cadenza 4
The Cadenza 4 is a $249 quad hybrid: a 10mm dual-chambered beryllium-coated dynamic driver paired with three balanced armatures, one Sonion and two Knowles. The midrange is the centre of gravity. It is described as natural and organic in timbre, articulate, detailed, with vocals placed slightly forward, and one review is titled around the midrange being the defining trait. The physical package draws steady praise too: 3D-printed resin shells with a machined aluminum faceplate are light enough to disappear over long sessions, passive isolation runs from strong to superb once the tips seal, and the bundled 392-strand silver-plated monocrystalline copper cable ships with swappable 2.5mm, 3.5mm and 4.4mm plugs. The disagreements sit around that midrange rather than in it. Bass quality is not in dispute (good definition, texture, clean sub-bass extension, no boom), but mid-bass punch is: one review flags a lack of impact as a con while others hear punch that is simply held in check, and quantity shifts with ear tip choice. Treble is smooth, rounded and non-fatiguing, and the upper treble is repeatedly described as rolled off, yet readings split on whether the top end still comes across as open and airy. Imaging draws opposing verdicts, and stage size is read as either wide and spacious or merely sufficient. The intended audience is not contested: this is not a bass-first or V-shaped set, and listeners chasing slam are pointed elsewhere.
