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.

Description
The 64 Audio Ocean IEM is the 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 behavior with up to 32 possible configurations.
The new Ocean IEM 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.
The new 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.
The new Ocean features a Champagne Copper coloured aluminum 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 includes 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.
