Zenith - Preorder
*Zenith is under preorder and will begin shipping at the end of April
Since the debut of our very first four-driver IEM, Helios, we have continuously pioneered, iterated and refined the art of four drivers. We have chased every acoustic nuance to its absolute limit, refining the four-driver architecture until every variable has been mastered.
That five-year-long journey ends here. This is Zenith.

FINAL. FORM. OF. FOUR
Zenith represents the culmination of everything we have learned. Every element has been min-maxed to perfection: driver selection, acoustic chamber geometry, crossover precision, venting volume and even internal wiring. Nothing is wasted. Nothing is left to compromise.
Zenith delivers a level of coherence, balance, and resolution that brute-force driver counts cannot replicate. It is so complete, so resolved, that to build another four-driver model would be redundant. We have reached the summit, not by climbing with more drivers, but by engineering the definitive expression of what drivers can achieve.

A Collaborative Effort
In the world of personal audio, good sound is expected. Great sound, however, requires something rarer: a meeting of minds. Together with Elise, we have widened our knowledge on what our audience expects and wants in great sound. We've cut out the noise and left only the best.
Zenith is the result of an exhaustive process spanning over fifteen unique prototypes, each one critically evaluated and refined. Throughout this development, we worked in close, continuous dialogue with Elise Audio. For over a year, every iteration was debated, adjusted, and re-evaluated until both teams agreed the tuning had achieved its intended balance of precision and musicality; representing the peak of its next-gen platform.
Resolution Without Compromise
At Zenith's heart lies an acoustic labyrinth, a chamber of mathematically modeled shapes made possible only by precision 3D printing. This process allows us to craft complex, organic structures that act as a sonic filter, eradicating unwanted resonances that traditional tube architectures grapple with. Crucially, this architecture is integrated with a pressure-relief vent for fatigue-free listening. Typically, vented designs come with a compromise: softening of resolution. Zenith refuses that compromise through its calculated structure.
Elevated Fit
Forged from high-grade T6 heat-treated AL6063 aluminium alloy, Zenith is as durable as all our models before, while sporting the same iconic shell design that we are known for.
However, Zenith features a nozzle first seen with Europa. Redesigned with feedback from our users, this allows Zenith to provide a more comfortable and secure fit that enhances the listening experience.
Refined Pressure Relief 💨
Venting IEMs have always been challenging for manufacturers particularly due to the risk of dirt and dust accumulation from suboptimal venting hole placement. This is doubly so with Zenith's all Balanced Armature design. We needed to maintain a specific bass output without the venting causing a negative effect on the SPL.
We addressed this issue with a two step venting system - Our chambering system first relieves pressure by venting into the internal cavity of the shell. The internal cavity then vents itself out via our uniquely placed under socket secondary vent. This unique approach minimizes potential dirt and dust build up over time while ensuring the delicate inner vent is not damaged from daily use.
All Things Internal
An IEM's internal wiring is its circulatory system, the unseen network that delivers punch, dynamics, and flow. In Zenith, wiring is not uniform. Each driver receives a dedicated wiring configuration, with varying gauge and material to optimise every driver’s sonic character and deliver every transient with authority.
All of these varying material types blend and combine to deliver the power needed to drive Zenith's unmistakable sound profile.
Cable Versatility At Its Finest
Zenith comes standard with our custom designed Altalune Audio Litmus Cable. This was originally commissioned to be the standardised cable paired with Giant. During the R&D phase, we realised we had (untapped) potential from the specific combination of material blend, solder and geometry. As such, we decided to maximise all aspects of Litmus.
Each exclusive Litmus cable comes terminated with super low impedance interchangable plugs with both 3.5mm and 4.4mm terminations, allowing for compatibility with a myriad of source devices on top of offering future-proof flexibility.

LISTENING NOTES
The Zenith delivers a sound that is both powerful and nuanced, starting from a foundation of thick, grounded bass and lower midrange. Kick drums land with palpable weight; stand-up bass lines feel fibrous and alive.
In the midrange, vocals and instruments are not merely separated but given their own distinct, three-dimensional space. You don’t just hear the singer; you sense the air around their voice, the subtle distance between their breath.
Up top, the treble is effortlessly extended without harshness. Cymbals reveal their texture without a hint of digital zing.
Amid it all, the Zenith casts a soundstage that is both wide and deep. Imaging is holographic, and each element is placed with pinpoint precision, yet never over-sharpened. The result is a complete, coherent, and remarkably 3D portrait of music.
Additionally, together with Elise's obsession on sources and amplification, we have been able to test and understand how Zenith scales from a simple dongle to multi-thousand dollar speaker amplifiers. Our final result doesn't hide its potential, it ascends. You don't have to own a desktop rig to enjoy it. But if you do, Zenith will be ready.
