Know before you buy
The A12t is designed for critical listening, offering a reference-level sound signature that provides exceptional detail across the entire frequency range. Its 12-driver configuration ensures high-fidelity reproduction, while the custom 3D-fit provides the isolation necessary for noisy professional environments.
Apex technology uses a specialized vent to release air pressure trapped in the ear canal. This not only reduces listener fatigue during long sessions but also creates a wider, more natural soundstage compared to traditional sealed IEMs.
Yes, thanks to 64 Audio's LID (Linear Impedance Design) technology. It ensures the IEM maintains a consistent frequency response regardless of the output impedance of your amplifier, phone, or audio interface.
No, the A12t features a low-impedance design with high sensitivity, meaning it can be driven effectively by most standard audio sources without needing a dedicated high-power amplifier.
The tia (Tubeless In-ear Audio) driver design removes the need for sound tubes and dampers. This allows the high frequencies to reach your ear with greater transparency and a more lifelike, open sound signature.
The A12t provides up to -20dB of passive noise isolation. Because these are custom-molded to your specific ear anatomy, they offer a significantly tighter seal than universal-fit headphones, effectively blocking out ambient noise in busy environments.
