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

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.

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.

Clean, neutral, and clear vocals. Reminds me of a cleaner Volume S or slightly better OG Oracle, but very expensive, maybe if you can find one around $1000 since it's more of a sidegrade to RSV, Mystic 8, and Arcanis vocal wise. If you want clean vocals Monarch MK2 does the same thing but for $700 less.

The Elysian Apostle delivers a V-shaped signature with a powerful, sub-bass-focused low end that offers substantial rumble and physicality, though some listeners might find it occasionally overwhelming or lacking in tight control. Its dual electrostatic drivers provide crisp, extended treble with good air and minimal harshness, while the midrange remains clear and natural despite slight recession, particularly excelling with vocal clarity and emotional delivery.

Comfort is mixed due to the large nozzle diameter, which demands extensive tip-rolling for a secure fit, though the lightweight aluminum shells are ergonomic for extended wear once settled. The Pentaconn ear connectors offer stability but limit third-party cable options, and the included accessories like the Divinus Velvet tips are functional but basic for the price tier.

Positioned as an "Annihilator Junior", the Apostle captures much of Elysian’s energetic house sound at a lower cost, offering strong technical performance like wide staging and solid resolution. However, its bass dominance and fit quirks make it less versatile across genres, appealing mainly to those seeking a fun, dynamic listen rather than strict neutrality.
