64 Audio U12t Reviews
As good as it gets. Great tuning and techs. Best set I've heard to date. Closest thing to speakers. Love it.
Amazing separation and presentation, amazing bass that extends down low and hits pretty authoritavely (not just in the context of BA sets - very good quantity and quality). Pretty interesting tuning with dialed down upper mids so certain instruments and voices seem more in front of you. Pretty clear sense of center image. Previously Owned
Terrific dynamic range and soundstage depth; the closest I have heard to a two-channel system in an IEM for these qualities. Precogvision Youtube Channel
TOTL tech. Mid-scoop can affect mids/vocal texture and placement, recessed midrange, treble is harsh at high volumes. Great bass detail, but could have more impact. Jays Audio Youtube Channel
Comment: Really clean sounding monitor with excellent technical aspects. Bass texture, superb clarity Can sound too sterile
Good resolution and dynamics with great imaging. Smooth, slightly recessed upper-mids with an upper treble peak.
Just Smooth and nice, great all arounder with smooth technicals, but too boring. Jaytiss Youtube Channel
Extremely versatile signature, great bass and details Potentially too safe tuning wise Tim Tuned Youtube Channel
Amazing bass (for a BA), top-tier resolution and detail-oriented signature. Crin Youtube Channel

The 64 Audio U12t is a mature flagship-class UIEM built around twelve balanced armatures per side and the company’s tia (open-BA) and apex pressure-relief tech; it lists at $1,999. Module options (mX/m15/m20) vary isolation from roughly −10 to −20 dB, giving modest control over perceived balance without changing the core tuning. The driver split—1 tia high, 1 high-mid, 6 mid, 4 low—aims for coherence via a 4-way crossover in a compact, aluminum shell.
Tonally the U12t trends neutral with a sub-bass lift, yielding clean mids and controlled, generally safe treble; frequency-response databases show the gentle low-end emphasis with even mids. Swapping apex modules can nudge the balance (e.g., M20 a bit more bass, M15 a touch airier) without altering the U12t’s fundamental character. Technical performance remains the calling card: resolution, imaging, layering, and BA-bass quality are repeatedly praised at the top of the class.
Trade-offs are mostly about preference and price: treble can read polite with minor quirks depending on chain and tips, and midrange body is slightly lean versus warmer sets. Given the premium MSRP, overall value hinges on prioritizing top-tier technicalities and long-session comfort via apex.

Bass go boom boom Because bass go boom boom so the highs go doom doom sometimes

The Linsoul x HBB Jupiter delivers a powerful bass-forward signature with an 11dB sub-bass shelf that avoids bleeding into the mids, resulting in a warm yet articulate low end. Its hybrid driver setup combines a 10mm dynamic driver with Sonion BAs for texture and speed, while four modified EST drivers provide extended, non-fatiguing treble with excellent air and detail retrieval. Vocals and instruments retain clarity despite the bass emphasis, making it versatile across genres like rock and electronic.
Technical performance stands out with precise imaging and a spacious soundstage that feels both wide and deep. The 5-way crossover ensures strong coherence across the tribrid array, though the upper mids occasionally present vocals as overly forward. Comfort is solid despite the 11-driver shells, but the sparse accessories and forgettable packaging feel mismatched for the price.
While positioned above competitors like the ThieAudio Monarch MKIII, the Jupiter justifies its cost with superior resolution and a more engaging bass response. However, its limited marketing and awkward pricing may hinder broader adoption. The included premium cable and ergonomic design are highlights, though tip selection could be more comprehensive.
