I usually don't like things that aren't all rounders but this might be the exception. Bass is incredible - best in class - great texture, fantastic physicality. Treble response is great too - pretty resolving. There is a noticeable recession in the upper mids, giving these a fairly U/V shaped sound signature - violins, for example, lack a bit of brightness/bite that I would hope for. But unlike other V-shaped IEMs, the mids aren't offensive. Incredibly fun to listen to. Probably the best single DD available. EQ highly recommended.

Excelllent bass - simply excellent. Midrange could use some work, as could the generally average imaging chops.

Well-resolving DD IEM with excellent treble control, though with somewhat weak mid-high harmonics.
Youtube Video Summary

Sennheiser’s IE900 delivers a sub-bass–focused tuning with tight control and real tactility, but its trademark upper-mid recession (≈2–5 kHz) keeps vocals and instruments a step back. A pronounced 9–10 kHz lift adds sparkle and air; depending on tolerance, that energy can read either engaging or a touch sharp/sibilant. Technical chops are strong for a single DD—resolution and microdetail are genuinely competitive.

The sticking point is tonal balance and value. While the IE900 is refined and punchy, that blunted midrange character contrasts with its bright treble, creating a love-it-or-leave-it “blue cheese” appeal. Against peers—and especially Sennheiser’s own IE600, which fixes the mids while preserving similar resolution—the IE900’s $1,300 price starts to look tough.

In short: choose the IE900 for its clean sub-bass slam, crisp transients, and airy top if that treble profile hits the spot. If the priority is natural mids and better value without giving up much technical ability, the IE600 feels like the smarter pick—and the real redemption of Sennheiser’s IEM line.

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.
