7Hz Timeless II
Approved coverage treats the Timeless II as a real second-generation effort rather than a rebadge: the dual-sided 14.5mm planar brings the punchy, fast bass the original was loved for, while the treble extends further and the stage opens up. The consensus verdict is that it is one of the strongest planar IEMs near $229, with the familiar planar caveats: upper-midrange energy that can turn edgy on bright recordings, and a large disc-shaped shell that not every ear tolerates. Compared with the original Timeless, reviewers hear a more refined, more extended, and slightly more expensive-sounding tuning, at a price that moved up alongside it.
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.
