The A4s Custom is a complete redesign with three armature drivers supplemented by a dynamic low-frequency driver, making it 64 Audio's second hybrid custom IEM in the lineup. This upgrade is enhanced by Tia, Apex, and 3D fit technologies. While the A4s Custom is targeted at musicians seeking new listening experiences, the detail and soundstage capabilities surpass other audiophile products at almost any price range.
Tia Technology:
A special design of drivers and housings without acoustic sound tubes provides transparent and realistic sound. The system reduces unwanted resonance and distortions, allowing the high-frequency Tia driver to sound freely within a single large sound tube. The A4s Custom are equipped with two key elements of the Tia system: the Tia driver and the shared sound tube.
Apex Technology:
The technology aims to alleviate listener fatigue by reducing excess air pressure in the ear canal. This ventilation allows musicians and music lovers to use the earphones comfortably for longer periods.
LID Technology:
By correcting the non-linear impedance of drivers, it ensures proper interaction with various sources. Whether you are a musician connecting to different devices at various concerts or studios, or an audiophile listening from low-impedance sources, LID ensures that your A4s Custom will sound consistently high.
3D Printing and Hand Assembly:
The main body is printed on a modern 3D printer using hypoallergenic hard acrylic. The colors and materials used by 64 Audio have been specifically chosen for durability. These materials also allow the digital images applied to maintain detail.
Once the body is printed, the production team assembles the remaining components by hand. All custom earphones are tuned and handmade based on your unique impressions. Wearing specially tailored earphones helps isolate external noise and provides a more comfortable listening experience compared to most universal earphones.
