Know before you buy
The 12 balanced armature drivers allow for a highly detailed and layered sound signature. By dedicating specific drivers to high, mid, and low frequencies, the U12t achieves exceptional clarity and separation that remains coherent across complex musical passages.
Apex technology uses a pressure-relief vent to release air trapped in the ear canal, which reduces listener fatigue during long sessions. It also allows you to swap modules to adjust the level of passive isolation and fine-tune the bass response.
Yes, thanks to 64 Audio’s LID (Linear Impedance Design) technology. It ensures the IEMs maintain a consistent frequency response regardless of the output impedance of the amplifier or device you are using.
Absolutely. The U12t is designed with a reference-level, transparent sound profile that provides the accuracy and detail required for critical listening and studio monitoring tasks.
The tia (Tubeless In-Ear Audio) system removes the need for sound tubes and dampers, which are common sources of resonance and distortion. This design allows for a more open, natural, and transparent high-frequency reproduction.
They are excellent for both. While they offer the technical precision professionals need, their comfortable universal fit and engaging, musical sound signature make them a top choice for any audiophile looking for a premium everyday listening experience.
