Our new benchmark for portable high-end audio performance, Ocean is fundamentally a 6-driver, 4-way system defined by a dynamically neutral sound signature and impressive broadband realism. Two custom dynamic cone-to-cone isobaric drivers, two mid-range balanced armature drivers, one high-mid balanced armature driver, and one tia™ high driver produce expansive imaging and instrument separation, balanced by a cohesive musical presentation. Beyond its default tuning, Ocean’s Passive Acoustic Control adds additional modularity to its sonic behaviour with up to 32 possible configurations.

Sound

A culmination of all that we’ve learned since our founding in 2010, Ocean presents a wide soundstage, excellent separation, and full-range clarity. Its iso-group provides a powerful and exceptionally clean low end. The mid-range is rich and present, leaving nothing to be desired. The upper mid-range, critical to our perception of realism, continues our tradition of striking a perfect balance between presence and subtlety.

Ocean features one of the very few additive tuning mechanisms in UIEM design: our remarkably effective tia waveguide. Further refined with our recently patented meta-material, and combined with the tia™ high driver, Ocean renders high frequencies with a lifelike, natural, and effortless character.

Presented in a Champagne Copper-coloured aluminium shell with a machined faceplate, Ocean’s design is inspired by aeolian ripples: geological patterns formed in sediment and shifted by the movement of wind. Our inclination toward minimalist design is in keeping with our brand identity, as well as an intentionally diametric response to current design trends in the market, especially among flagship products.

Ocean is the ultimate tinkerer’s UIEM and the next volume in 64 Audio’s anthology.

Ocean Shielded Cable

Ocean comes standard with two shielded cables, terminated in 3.5mm and balanced 4.4mm. Its four-core cross-braided wires are made of silver-plated, single-crystal copper (UP-OCC); offering outstanding noise shielding and transparent signal transmission, with a low impedance of just 0.29Ω.

PASSIVE ACOUSTIC CONTROL

Shape the acoustic response of Ocean with two stainless steel tia™ screens that control high-frequency damping and four back-vent filters which regulate the pneumatic loading of the isobaric dynamic drivers. Along with its four apex™ modules, there are 32 different combinations for a truly custom sound signature.

Patented Technology

tia

Tubeless In-Ear Audio (tia) is a patented IEM design methodology that aims to reduce unwanted resonance and distortion for a transparent and lifelike sound signature. The tia system is comprised of three major elements: open balanced armature tia drivers, the tia single-bore design, and tia acoustic chambers. Ocean features two major elements of the tia system: the tia driver and the tia single-bore design.

apex

Air Pressure Exchange (Apex) is a patented vent that releases air pressure in a sealed ear canal all while retaining standard IEM levels of isolation; enabling musicians and music enthusiasts to listen more comfortably for longer. This venting alleviates listener fatigue and allows for a much more realistic soundstage. Apex comes in three module variations for Ocean: mX, m12, m15, and m20.

LID

Linear Impedance Design (LID) is a patented circuit that corrects the non-linear electrical resistance of the multiple driver-sets comprising this 6-driver IEM. Varying source amplifier output impedance in devices like smartphones, body packs, DAC/amps, and DAPs typically results in varying frequency response across them, depending on the increase in resistance. Restoring proper interaction with the source and preserving the desired sound signature enables a consistent reliable sound.
