64 Audio Solo Single Planar Magnetic Driver Universal IEM Earphones

 

64 Audio's Solo reimagines the standards of full-range sound in portable high-end audio, covering the entire sonic spectrum with a single planar driver. As the latest evolution in their legendary tia™ line, Solo takes inspiration from the pioneering design of Fourté, Trio, and Duo. To tackle the challenge of tuning a single driver, 64 Audio has paired a traditional electronic filter with the world's first Helmholtz resonator in an in-ear monitor (IEM). Additionally, the LID technology offers transparent response, an powerful low end and unmatched sound signature.

 

 

What 64 Audio say about the Solo

As 64 Audio’s first single-driver UIEM, Solo opens up new possibilities in micro-acoustic design, proving that a single driver can deliver exceptional resolution and sound quality.

The 14.2mm planar driver’s acoustic chamber features two precisely tuned Helmholtz resonators, sculpting its frequency response while incorporating 64 Audio's apex core design. This combination relieves pneumatic pressure and enhances spatial depth, delivering a remarkable listening experience. Additionally, with the patented LID technology, all innovations come together in one of 64 Audio’s most striking designs since Fourté in 2016.

 

Features

  • Planar magnetic driver delivers full-range sound with exceptional clarity
  • Helmholtz resonators enhance acoustic tuning and frequency balance
  • LID® technology ensures consistent sound across all devices
  • Apex® Core reduces pressure for greater comfort and immersive sound
  • Includes pure OCC copper eight-braid cable with 3.5mm and 4.4mm connectors

 

The Sound

64 Audio Solo upholds the brand's high standards of accuracy, musicality, and balance while introducing innovative speaker technology with a single planar driver per side. The planar driver delivers ultra-realistic sound by capturing subtle details and eliminating sharpness through acoustic notch filters. Combined with the Apex Core, it creates a wide soundstage with impactful bass and deep sub-bass, ensuring immersive listening, even in complex mixes.

 

Copper Eight-Braid Cable

Solo is being paired with our first pure copper cable. The OCC Copper, which is 23 x 25 AWG Wires, is built into eight-braids with a pleasant tactile feel as well as an impressively low 0.26Ω impedance rating. Solo comes standard with two of these cables, one 3.5mm single-ended and one balanced 4.4mm.

 

LID®

Linear Impedance Design (LID) is a patented circuit that compensates for the non-linear electrical resistance resulting from Solo’s electronic shelf filter. Variations in source amplifier output impedance in devices like smartphones, body packs, DAC/amps, and DAPs typically lead to changes in frequency response. LID restores proper interaction with the source, preserving the intended sound signature and ensuring consistent, reliable performance.

 

Helmholtz Resonators

Planar magnetic technology has been around in portable hi-fi for years, but 64 Audio wanted to unlock its full potential. To achieve this, they needed a slight reduction in high frequencies and attenuation of narrow frequency bands. While an electronic filter subtly adjusts the highs, 64 Audio incorporated two 3D-printed Helmholtz resonators into the Solo’s sound chamber. These resonators manipulate air resonance at specific frequencies, precisely amplifying or reducing targeted frequencies for optimal sound quality.

 

Apex Core

Adding to our list of innovations, we implement our patented pressure-relieving technology in the form of apex core, elevating this design to new levels of fidelity and spatial acuity. Because Solo’s acoustic chamber includes our integrated apex core technology, we achieve a similar fit and comfort to that of the Duo. The design offers just enough isolation to allow the listener to focus on the audio while feeling so unimpeded that you may initially wonder if you have a proper seal. This ensures hours of comfortable listening, made possible by our patented technology.

Yes. 64 Audio in-ear monitors are trusted by touring musicians and sound engineers worldwide. Their secure fit, balanced tuning, and reliable build quality make them ideal for demanding live environments.
Loading...
Models like the U12t and U18s are highly regarded among audiophiles. They offer exceptional clarity, soundstage, and detail retrieval. The right model depends on your sound preferences and source equipment.
Loading...
Absolutely. Future Shop is an authorised UK retailer for 64 Audio. All earphones are supplied brand new, with full manufacturer warranties and UK-based support.
Loading...
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.
