Description

64 Audio U12t

The 64 Audio U12t delivers an immersive, high-fidelity listening experience with exceptional spatial imaging and balanced sound. Its articulate highs extend beautifully, while the warm low-end response ensures an engaging yet accurate performance. Designed for both audiophiles and professionals, the U12t offers reference-level detail in a universal fit.

Equipped with 64 Audio’s patented tia technology, the U12t eliminates unwanted resonance and distortion, ensuring a transparent and lifelike sound. The combination of the tia driver and single-bore design enhances clarity across all frequencies. Featuring Apex technology, the U12t relieves in-ear pressure, reducing listener fatigue while maintaining isolation. Three Apex module options (mX, m15, and m20) allow users to customize the soundstage and isolation.

The U12t now comes standard with the premium Pearl Premium Cable, offering both 3.5mm single-ended and 4.4mm balanced connections for superior signal transmission. Additionally, 64 Audio’s Linear Impedance Design (LID) ensures a consistent frequency response across different audio sources, preserving the intended sound signature regardless of the device.

Pearl Premium Cable

The U12t now comes standard with the Pearl Premium Cable, designed for superior audio transmission and durability. This high-quality cable includes both 3.5mm single-ended and 4.4mm balanced connections, allowing users to optimize their listening experience across various audio setups.

TIA Technology

64 Audio’s patented Tubeless In-Ear Audio (tia) technology eliminates unwanted resonance and distortion for a crystal-clear sound. By incorporating open balanced armature tia drivers and a single-bore design, the U12t delivers an exceptionally natural and transparent audio experience.

APEX Venting System

The Air Pressure Exchange (Apex) system is a revolutionary venting technology that reduces in-ear pressure while maintaining sound isolation. This minimizes listener fatigue, making extended listening sessions more comfortable. The U12t includes three Apex module options (mX, m15, and m20) for customizable isolation and airflow.

LID for Consistent Sound

Linear Impedance Design (LID) ensures that the U12t maintains a consistent frequency response across different devices. This innovative circuit corrects variations in electrical resistance, preserving the intended sound signature regardless of the connected source, from smartphones to professional DACs.

Precision Engineering

Each U12t is meticulously crafted from a solid piece of aluminium for both durability and comfort. The brushed aluminium faceplate not only enhances its premium aesthetic but also ensures a lightweight, ergonomic fit for hours of fatigue-free listening.

Immersive, High-Fidelity Sound

With 12 precision-balanced armature drivers, the U12t delivers a rich and detailed audio performance. The combination of deep, controlled bass, smooth mids, and articulate highs results in an expansive soundstage, making it ideal for both audiophiles and professional users.

64 Audio specialises in high-performance in-ear monitors (IEMs), for musicians, sound engineers and audiophiles who want a more precise, personal way to hear music. The brand is best known for its universal…
