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 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.

The tia design uses an open driver layout

tia stands for Tubeless In-Ear Audio. 64 Audio says the design pairs open balanced armature drivers with a single large bore and tuned chambers, aimed at a wider soundstage and a smooth response. Not every model uses it, so check the product page for the one you are considering.

Apex vents pressure and sets isolation

Apex stands for air pressure exchange. 64 Audio says the vent relieves pressure in the ear canal to reduce listening fatigue. Replaceable isolation modules let you choose how much outside noise reaches you: the m20 module cuts 20dB, the m15 cuts 15dB and the mX cuts 10dB.

Custom and universal ranges sit side by side

The catalogue is divided into universal and custom ranges. Custom models are made from a digital scan of your ear and a 3D-printed shell, a process 64 Audio calls 3D-Fit. The company also names LID, short for linear impedance design, as a technology used across its multi-driver models.

Frequently Asked Questions

Start with power (cables & distribution), then upgrade signal cabling, support (Hi-Fi Racks) and isolation accessories. These incremental changes can unlock more from your existing gear. Once you have the basic essentials, then you can look at further upgrades, such as fuses, cartridges, better isolation and more!
Loading...
It is usually best to address obvious issues first, such as unstable equipment placement or poor isolation, before adding more specialised accessories. Call (0208 905 1555) or Email (sales@futureshop.co.uk) one of our consultants to identify an ideal upgrade path for your system.
Loading...
A high-quality hi-fi system is built around a few core elements working together. At its heart is a source, such as a streamer, turntable, CD player, or digital audio player, which provides the music. This signal is then shaped and boosted by amplification, which may include an integrated amplifier, headphone amplifier, or phono stage depending on the system. The sound is delivered through speakers or headphones, which have a major influence on the overall character of what you hear. Supporting components also play an important role. DACs improve digital playback quality, cartridges and phono stages are vital for vinyl, and hi-fi racks, speaker stands, and isolation products help equipment perform consistently. A balanced system does not rely on one standout component, but on how well everything works together.
Loading...
Isolation and support products can make a clearly audible difference, especially in resolving systems. Vibrations from floors, speakers, and even airborne sound can interfere with sensitive components like turntables, DACs, and amplifiers. Proper speaker stands help speakers perform as intended by improving stability, positioning, and bass control. Hi-fi racks and isolation platforms reduce unwanted resonance, helping systems sound cleaner, more focused, and more consistent. While these products may not change the sound as dramatically as speakers or cartridges, they often unlock performance that is already there but being masked by vibration or poor placement.
Loading...
That depends on the starting point of the system. If the fundamentals are weak, such as entry-level speakers, poor setup, or missing core components, starting with the basics usually brings the biggest gains. A well-matched foundation allows later upgrades to shine. If the system is already balanced, upgrading individual components can be very effective. Improvements such as a better cartridge, DAC, phono stage, or isolation can refine detail, clarity, and realism. The most rewarding upgrades tend to be those that address the system’s weakest link rather than focusing on one category alone.
Loading...
In many systems, the biggest improvement comes from upgrading speakers or headphones, as these shape the sound more than any other component. For vinyl systems, the cartridge and phono stage are often the most influential upgrades. In digital systems, a higher-quality DAC or streamer can significantly improve clarity and timing. Beyond electronics, addressing setup, isolation, and support is often overlooked but highly effective. Improving speaker positioning, adding proper stands, or isolating sensitive equipment can deliver noticeable gains without changing core components. The best first upgrade is usually the one that removes the most obvious limitation in the current system.
Loading...
There are lots of components and tweaks that can offer a lift in performance, however, our current favourite is the UK 13A mains fuse from your wall socket to your distribution block or amplifier. This is an often overlooked component in most systems but the improvements far outweigh it's size and cost.
