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.

Aspire 2's 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.

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 3 users get the benefits of 64 Audio's flagship technology with -20dB of isolation combined with ear saving venting.

The Aspire 3's waveguide is a 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.

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.
