64 Audio Aspire 2 Universal IEM Earphones

64 Audio Aspire 2 Universal IEM Earphones

The 64 Audio Aspire 2 is a professional universal in-ear monitor built around a two-driver configuration that pairs a dynamic driver for low-end weight with a balanced armature handling the mids and highs. The result is a bass-forward sound signature with extended treble presence, designed to give musicians and live performers a full, energetic representation of their monitor mix without sacrificing clarity in the upper frequencies. With a sensitivity of 103dB and an impedance of 13 ohms, the Aspire 2 is easy to drive from a wide range of sources, making it a practical and versatile choice for stage and studio use alike.

Three core technologies shape how the Aspire 2 performs in practice. Apex Core is 64 Audio's pressure relief system, integrated directly into the earphone body, which reduces the pneumatic pressure that builds up during extended wear. This makes long listening sessions and performances significantly more comfortable while also contributing to a more natural bass response. The Helmholtz Resonator is a custom acoustic structure mounted to the balanced armature driver that focuses and directs high-frequency energy for a cleaner, more controlled treble presentation. Meanwhile, the LID circuit corrects for the non-linear impedance behaviour common in multi-driver designs, ensuring the intended sound signature is preserved regardless of the output impedance of the connected source.

Built with a moulded ABS shell and a stainless steel nozzle with a flanged design and mesh grill, the Aspire 2 is constructed to withstand the demands of regular professional use. The nozzle design keeps ear tips securely in place and protects the sound bore from debris, both practical considerations for performers. Supplied with foam and silicone ear tips, a carry case, cleaning tool, and a quarter-inch adapter, the Aspire 2 arrives ready for immediate use and backed by a 24-month manufacturer warranty. 

Here is what 64 Audio say about the Aspire 2

64 Audio Aspire 2 combines a balanced armature (BA) driver with a dynamic driver (DD) for a bass-forward sound with extended highs. Apex Core technology relieves pressure for enhanced bass and comfort, while the Helmholtz Resonator eliminates resonance for precise tuning. A built-in corrective circuit ensures consistent sound across multiple sources.

Part of 64 Audio’s Aspire Series, Aspire 2 offers pro-level sound in a universal IEM designed for musicians and live performers. Ideal for newcomers to in-ears, backup sets, or non-custom users, its ergonomic design, ABS shell, and stainless steel nozzle ensure lasting durability and secure fit.

Crafted by 64 Audio’s expert team, Aspire 2 blends powerful bass, clear mids, and sparkling highs for an engaging yet accurate sound. Helmholtz Resonator tuning and Apex Core pressure relief create fatigue-free listening, making Aspire 2 a standout choice for demanding musicians and audiophiles.

Aspire 2

Monitor your performance with 64 Audio's professional universal in-ear monitors (UIEM) specifically designed for musicians and live music professionals. Aspire 2 is a two-driver IEM with a bass-forward sound signature, complimented by extended highs, offering pro-level performance in an ergonomic design.

LID Technology

LID is a proprietary circuit that corrects the non-linear impedances of the drivers, restoring proper interaction with the source and preserving the desired sound signature.

Apex Core

64 Audio's patented technology seamlessly integrated into the body of the earphone. The pressure relieving channel provides our controlled leak via acoustic filters as opposed to pneumatically interactive foam in our traditional Apex implementation.

Helmholz Resonator

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.

Stainless Steel Nozzle

The stainless steel nozzle, coupled to the moulded ABS shell, provides durability needed for consistent use and the removal of ear tips. With a flange design and mesh grill, ear tips won’t fall off by mistake and the sound bore will remain free of debris.
