64 Audio Tia Trio VS Lime Ears Pneuma

Youtube Video Summary

The tia Trio mirrors 64 Audio’s flagship DNA at a lower price point ($2,299) with the same compact, lightweight aluminum build, generous tip selection, and a comfortable shell that suits smaller ears. Sonically it carries a present but well-judged bass shelf, adding a touch of warmth by settling around ~180Hz rather than the usual sub-bass focus. Crucially, the midrange corrects the Forte’s biggest flaw: upper mids aren’t hollowed out here. There’s a mild 1.5–3k dip (about 1–2dB), yet vocals and instruments remain properly contoured and far more natural and engaging without requiring EQ.

Up top, the Trio shows recognizable treble landmarks—an emphasis near 5k that can sound a bit shouty and another at 8k adding slight sizzle—tempered by the healthier mids, so the presentation is lively without becoming harsh. Treble extension is excellent, with “air” above 10k running a tad hot depending on taste. On technicalities, detail retrieval and image clarity track surprisingly close to both the Forte and Legend Evo; the soundstage is expansive for an IEM (strong depth and layering) though not as outsized as Forte, and imaging is accurate for music but not surgical enough for competitive FPS. Taken as a whole—and especially without EQ—the tia Trio feels like the more complete listen: a high-end IEM that preserves the fun while fixing the midrange, trading only a slice of stage grandeur for a much more balanced, recommendable experience.

The tia Trio comes across as a hybrid with personality: rich, thick, and warm, with slightly forward treble that adds air without tipping into the harsher edge heard on the U18t. Vocals are pulled back, yet the presentation feels cohesive and surprisingly natural given its unconventional response. What really stands out is the depth and head-stage—a wraparound sense of space that feels more immersive than most peers, making guitar strums and ambient cues pop in a way that’s immediately engaging.

Despite the 1DD + 2BA configuration, bass isn’t a simple upgrade over the U12t’s BA low end; it carries a touch more body and plosive weight but can feel a bit slower and less refined. Still, detail retrieval punches well above the driver count, and the overall tuning—while relaxed in the mids—stays clean and exciting. With the usual 64 Audio caveats (no apex swapping here and a mediocre stock cable), the tia Trio earns a five-star verdict for its intoxicating stage and atmosphere, even if it’s not the safest all-rounder at its $2,300 price.

Presentation screams boutique: a big Pelican-style case, green confetti, branded pouches, and a signed QC card. The stock cable is a PW Audio #10 in 3.5 mm, hinting at upscale intent, and the shells are huge with color-shifting glitter plates that look unapologetically premium. Price turns out to be around €1,800 (~$1,900), with Universal and Custom offered at the same tag, plus deep customization options. Cable rolling shows audible shifts, but the star is the hardware on the shells: a proper flickable switch, not a pin-poker—practical and satisfying.

Under the hood sits a five-way hybrid: four BAs and a 7 mm titanium dynamic driver dedicated to sub-bass. That switch doesn’t just nudge bass; it tilts the whole response—adding warmth, lifting low end, and even taming treble edge/sibilance (think Fletcher-Munson savvy). Down position reads flatter; up position fattens the foundation and smooths the bite. Build is bulky but comfortable, and the tuning tools invite genuine on-the-fly tailoring track by track.

Performance hits hard: sub-bass is deeper than a 7 mm has any right to be, the midrange stays clean, and the treble can be made polite or vivid with a flick. The overall vibe is fast, energetic, and intensely engaging rather than laid-back, with standout detail, expansive soundstage, and precise imaging. It behaves like a true kilobuck flagship—big, bold, and addictive—making a confident recommendation despite the sticker shock, especially for listeners who want switchable character without sacrificing technical chops.
