Aspire 2 is a Two-Driver IEM with a Bass-Forward Sound Signature, Complimented by Extended Highs

• Second IEM in the new 64 Audio Aspire Series lineup
• Crafted with (1x) DD + (1x) BA driver
• Apex Core provides pressure release for great bass response and long listening sessions
• Helmholtz Resonator eliminates resonance by targeting frequencies for optimum tuning
• Corrective circuit eliminates sound variance between a number of sources

Aspire Series

Aspire Series IEMs empower musicians to monitor their performances with the same sonic excellence and industry-shaping technology used by some of the world's greatest performers. Whether you're just getting into in-ear monitoring, not ready for customs, need a back-up set or simply prefer universal-fit products, Aspire Series UIEMs are designed to accommodate the widest range of ears.

In addition to their crowd-pleasing ergonomics and fit, the four models offer distinct variations of sound signatures, within neutral preference bounds, to suit any musician or singer.

Aspire 2

Aspire 2's bass-forward sound signature is complemented by extended highs and wide soundstage built into a form-factor that prioritizes ergonomics without sacrificing technical capabilities. All designed and engineered by the innovative team responsible for the industry standard audio gear that 64 Audio is famous for.

Two-Driver IEMs

A dual-driver system with a two-way crossover system provides increased flexibility in tuning. By leveraging the unique characteristics of both dynamic and balanced armature drivers, Aspire 2 delivers focused low-end impact alongside details mids and highs. Additionally, its integrated Helmholtz Resonator technology helps achieve a forward low-end presentation with an elevated high-frequency response without harshness.

Technology

apex core
64 Audio's patented technology is seamlessly integrated into the body of the earphone. The pressure relieving channel provides controlled venting via acoustic filters. Aspire 2 users get the benefits of 64 Audio's flagship technology with -20dB of isolation combined with ear saving venting.

Helmholtz Resonator
3D Printed micro-cavities operate by forcing air in and out, causing the air inside to resonate at a specific frequency. By precisely determining the dimensions of the cavity and its neck, we can target a very narrow resonant frequency to amplify or diminish.

LID
Linear Impedance Design is a patented circuit that corrects non-linear electrical resistance across multiple driver-sets. Inconsistent impedance across varying devices/sources often results in varying frequency response. Restoring proper interaction with the source enables consistent, reliable sound.
