64 Audio Solo Universal Planar Magnetic IEM
The 64 Audio Solo redefines what’s possible from a single driver in a universal in-ear monitor. Crafted around a cutting-edge 14.2mm planar magnetic driver, Solo delivers true full-range sound with exceptional clarity, impact, and texture. This IEM merges modern innovation with classical acoustic techniques—like dual Helmholtz Resonators and apex® core pressure relief—to create a highly refined, immersive listening experience. Enhanced with patented LID™ (Linear Impedance Design) and tia™ single-bore architecture, Solo maintains tonal accuracy across sources while maximizing detail, realism, and spatial presentation. Finished with precision-machined aluminum shells and paired with two premium copper eight-braid cables, the Solo stands as a monumental evolution in planar IEM performance.

Q&A Section
Q: What makes the 64 Audio Solo different from other IEMs?
A: Unlike traditional multi-driver IEMs, Solo uses a single 14.2mm planar magnetic driver paired with innovative acoustic and electronic technologies to deliver full-range sound with stunning clarity and natural tonal balance.
Q: Does Solo provide strong bass even with just one driver?
A: Yes, thanks to its specially tuned acoustic chamber and Helmholtz Resonators, Solo offers deep sub-bass and impactful low frequencies without muddying the mids or highs.
Q: Can I use the Solo with my smartphone or DAP?
A: Absolutely. With LID™ technology, Solo ensures a consistent sound signature across devices with different output impedances, including smartphones, DACs, and amplifiers.
Q: What is the purpose of apex® core?
A: apex® core relieves inner-ear pressure for more comfortable long-term listening and creates a wider, more natural soundstage.
Q: Are different cables included?
A: Yes, Solo comes with two OCC copper eight-braid cables: one single-ended 3.5mm and one balanced 4.4mm, both designed for low resistance and optimal sound.
Q: How isolating are these IEMs?
A: Solo offers -12 dB of passive noise isolation—enough to reduce ambient noise while maintaining an open and natural listening experience.
Q: What ear tips are included with the Solo?
A: You get a complete fit kit: TrueFidelity foam tips, SpinFit silicone tips, and standard silicone tips—all in sizes S, M, and L.
Q: Is the Solo comfortable for extended listening sessions?
A: Yes, Solo’s pressure-relieving apex® core design and ergonomic fit ensure all-day comfort with reduced ear fatigue.
