Slight harshness in the trebble, but competent, lovely set.
Youtube Video Summary

Metalure Glacier rolls in as a nine-driver hybrid (DD+BA+EST) around $1,600, proudly made in the USA, and it looks the part: a metallic, semi-custom shell with a gold nozzle, clean L/R markings, and flat 0.78mm 2-pin sockets. The stock cable feels substantial with a working chin slider and tidy Y-split, and the matching case leans premium. Fit is easy—slightly compact shell, secure seal, zero comfort complaints.

Sonically it’s a bassy, clean presentation with good micro-detail, natural male/female vocals, and a tasteful bass shelf. The graph tells the story: a bit of upper-mid lift, a spicy ~8 kHz peak, and a notable 5–6 kHz dip that darkens the mid-treble, trading some “twinkle” (11–13 kHz) for smoothness. Despite the energy up top, it doesn’t shout; balance is helped by the low-end weight. Sensitivity around 3 kHz/8 kHz will decide comfort for some ears, and a touch of EQ—easing upper-mids/8 kHz—can make it even more even-keeled.

Against peers, Elysian Acoustic Labs Apostle brings thicker mids, stronger bass and imaging with less 8 kHz bite; DUNU Glacier feels more refined in bass texture and air yet the Metalure counters with a richer, fun tilt many will prefer. A “YU9” comparator sounds a bit flatter and less peaky up top but can’t match the build and accessories here. Net takeaway: a fun, detailed all-rounder with minor treble quirks, strong ergonomics, and genuine high-end execution. It earns an S–-tier nod—potential endgame for listeners who vibe with its V-leaning balance.

The Metalure Glacier is a 9-driver tribrid—1DD+6BA+2EST—positioned as the brand’s flagship; this configuration is confirmed in independent coverage and frames its focus on treble extension and layering . MSRP is listed at $1,629 on the manufacturer’s store, and accessories include a balanced 4.4 mm cable and leather carry case, aligning the package with flagship norms .

Tonally, reports describe a controlled sub-bass lift with clean mids and extended upper-treble “air,” yielding strong clarity and a notably large soundstage for spacious, layered mixes rather than overt warmth . Driveability is straightforward given its published 11 Ω impedance and 120 dB/mW sensitivity, though the combination also implies sensitivity to source noise; a quiet source is advisable .

Technically, the Glacier’s strengths are stage width, separation, and treble resolution, with imaging that remains stable in dense passages—traits repeatedly highlighted in third-party impressions . At its price, the value case hinges on whether a spacious, “airy” presentation and top-end finesse outweigh a comparatively restrained mid-bass warmth; those priorities will determine how compelling its overall proposition is.
