64 Audio Aspire 4

Experience unparalleled performance with 64 Audio's new monitoring tool Aspire 4, featuring the same advanced technology and sonic excellence as 64 Audio's custom in-ear monitors used by top performers worldwide. This ergonomic design prioritizes comfort without compromising on performance, all crafted by the innovative team behind 64 Audio's renowned audio gear.
The patented technology Apex Core is seamlessly integrated into the earphones, with a pressure-relieving channel that uses acoustic filters instead of traditional foam. This design significantly reduces ear fatigue while maintaining around -20dB of noise isolation, ensuring long-lasting comfort for Aspire 4 users.
The Linear Impedance Design (LID) corrects non-linear electrical resistance in the 6-driver IEM, delivering consistent frequency response across various devices. A custom waveguide enhances driver efficiency, directing energy for crisp, clear sound, offering an experience comparable to 64 Audio's patented tia™ high-driver.
Audio bliss unlocked.

Cutting Edge
The epitome of audio mastery with 64 Audio's latest monitoring innovation. A cutting-edge performance tool embodying sonic brilliance and ergonomic finesse, meticulously engineered by the visionary minds behind 64 Audio's acclaimed audio legacy.

Apex Core
This patented technology seamlessly integrated into the body of the earphone. The pressure relieving channel provides a controlled leak via acoustic filters as opposed to pneumatically interactive foam in the traditional Apex™ implementation. Aspire 4 users can significantly reduce ear fatigue while maintaining roughly -20db of noise isolation.

LID
Linear Impedance Design (LID) is a patented circuit that corrects the non-linear electrical resistance of the multiple driver-sets comprising this 6 driver IEM. Varying source amplifier output impedance in devices like smartphones, body packs, DAC/amps, and DAPs typically results in varying frequency response across them, depending on the increase in resistance. Restoring proper interaction with the source and preserving the desired sound signature enables a consistent reliable sound.

Waveguide
Custom designed acoustic structure integrated onto the high-frequency balanced armature driver. Unique in its shape and implementation, this waveguide increases the driver’s efficiency by directing and focusing its energy for a crisp and clear sound. While hard to compete with the legendary response of 64 Audio's patented tia™ high-driver, this configuration may be the closest thing to it on the market.
