64 Audio A4t Earphone
The A4t is the entry point for anyone seeking the remarkable smoothness and extension of the tia™ technology. Built on the foundation of our successful 4-driver design, the new A4t delivers an immersive listening experience with a lively mid-range and powerful bass. Its sound signature is balanced and neutral, shining forth with a new level of clarity thanks to the tia driver and the tia single-bore that aids in removing unwanted resonance and distortion.
Featured in the A4t is apex™, a pneumatically-interactive vent that relieves fatigue-causing sound pressure inherent in other earphone designs. Also featured is LID technology, ensuring the A4t maintains its sound signature regardless of the source - perfect for musicians and music lovers plugging into a variety of equipment.

A revolutionary technology that eliminates pneumatic pressure that causes excessive eardrum movement.
tia HIGH DRIVER
The tia high driver is located in the tia single bore (canal stem). Because of the extremely short sound path of the high driver, we’ve achieved a remarkable high-frequency extension and smoothness.
By removing pneumatic pressure from the ear canal, sound is felt to be more spacious and outside the head when compared to traditional earphones.
Sound bores are used to channel the sound from a driver or a group of drivers to the eardrum. Multi-bore designs allow unique frequency shaping capabilities.
