This Planar lines up with the 64 Audio house sound. There are better options for Planars and this sound signature.

Warm and shimmery with excellent imaging. Dampening in the mid-treble elevates this above the standard planar IEM experience.

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.
