Welcome to the “First Look” of the 64 Audio Ocean, the brand’s first all-new flagship universal in-ear monitor since the Fourté launched back in 2016.
Kind of product?
The 64 Audio Ocean is a flagship universal-fit in-ear monitor (UIEM) built around a 6-driver, 4-way hybrid layout: two custom cone-to-cone isobaric dynamic drivers for bass, two mid-range balanced armatures, one high-mid balanced armature, and 64 Audio’s own tia™ high driver for the treble. On paper, that combination is aimed squarely at broadband realism and a wide, cohesive soundstage rather than an exaggerated house sound.
Brand?
64 Audio is the California-based in-ear monitor specialist founded in 2010, known among touring musicians and audiophiles alike for its tia™ driver technology and Apex-module tuning system. The 64 Audio Ocean is presented as “a culmination of all that we’ve learned since our founding,” and it slots in as the newest volume in the company’s in-ear monitor anthology.
Current price?
The 64 Audio Ocean is listed at $3,999 on the official 64 Audio website, where it currently shows as “Coming Soon” with a notify-me signup rather than an active buy button — so early adopters will need to wait a little longer for shipping to begin.
What’s in the box?
The 64 Audio Ocean ships with a comprehensive accessory set: the universal-fit monitors themselves, a hard carrying case, three sets of TrueFidelity foam tips (S/M/L), three sets of SpinFit silicone tips (S/M/L), three sets of standard silicone tips (S/M/L), a 3.5mm shielded cable, a 4.4mm balanced shielded cable, a shirt clip, a cleaning tool, a cleaning cloth, a round sticker, and the full set of Apex tuning modules (m20, m15, m12 and mX).
Features?
Here are a handful of standout features on the 64 Audio Ocean:
- Passive Acoustic Control: two stainless steel tia™ screens plus four back-vent filters give up to 32 possible tuning combinations without any DSP involved.
- Refined tia™ waveguide: now paired with a newly patented meta-material, aimed at a natural, effortless top end.
- Champagne Copper shell: a T6061 aluminum shell with a machined faceplate, its ripple pattern inspired by aeolian sediment formations.
- Dual shielded cables included: both terminate in 3.5mm and balanced 4.4mm, built from silver-plated single-crystal copper (UP-OCC) for a low 0.29Ω total impedance.
- US-based build: designed, assembled and quality-checked in the United States.

Closer look?
The 64 Audio Ocean show a shell shape that leans minimalist compared to many current flagship UIEMs, with a clean, linear ripple pattern machined into the faceplate rather than a busy multi-color finish. The two included cables both use a four-core cross-braided UP-OCC copper construction, and the tuning system is entirely mechanical: swap the tia™ screens or back-vent filters, and the 64 Audio Ocean’s response changes without touching an app or a DSP setting. For musicians who already rely on in-ear monitors on stage, that Apex module system carries over directly from 64 Audio’s professional monitoring lineage — a similar philosophy to what we saw on the Sony IER-M500 in-ear monitors for live performers, though the 64 Audio Ocean pushes further into pure tinkerer territory with its 32 configurations.
For whom is this product?
The 64 Audio Ocean is aimed at listeners who already know they want a flagship-tier UIEM and who enjoy fine-tuning their sound rather than accepting a single fixed voicing. Touring musicians familiar with 64 Audio’s stage-monitor heritage, and desktop or portable-audio enthusiasts chasing a neutral-leaning, broadband-realistic signature, both look like the intended audience. At $3,999, this is squarely a flagship purchase rather than an impulse buy.
Conclusion?
The 64 Audio Ocean looks like a genuinely considered flagship rather than a spec-sheet refresh: a 6-driver, 4-way hybrid platform, a mechanical tuning system with up to 32 combinations, and a distinctive Champagne Copper finish that breaks from current flagship design trends. We haven’t heard it yet, and 64 Audio itself still lists the 64 Audio Ocean as “Coming Soon,” but on paper this is one of the more interesting flagship in-ear monitors of the year for anyone who wants to shape their own sound. We’ll be watching for the full launch and, ideally, a chance to spend real listening time with it.
