A more correct sounding version of the Fourte with slight cutbacks in staging and sheer resolution.

Youtube Video Summary

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.

Phenomenal bass texture and quality. Mids are good if not great - I don't have much to nitpick about them - good note weight and excellent clarity. Treble is very sparkly and airy though some may find it a bit too much - I think the extra spice actually helps with instruments like violins. Imaging isn't quite as precise as U12T but stage is just as large if not more so. Timbre is not exactly natural but it is very good and definitely not offensive at all. My subjective favorite IEM to date. This is without a doubt a colored listen but it is so satisfying. Makes U12T sound almost sterile. That said both are good counterpoints to each other.

Best bass texture ever. Gorgeous treble extension, stage and imaging. Coherency and timbre a bit off. Upper mids/lower treble could be better. As amazing as it is, I couldn't fully connect with it (musically). Price is the biggest con.

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.
