64 Audio Ocean Universal In-Ear Monitors
Product Description
The 64 Audio Ocean is a flagship universal in-ear monitor engineered to deliver dynamically neutral, full-range sound with exceptional realism, imaging, and musical cohesion. Built around a sophisticated six-driver, four-way hybrid system, Ocean combines two custom cone-to-cone isobaric dynamic drivers for the lows, two balanced armature midrange drivers, one high-mid balanced armature driver, and one tia™ high-frequency driver.
Ocean's dual dynamic driver iso-group delivers powerful, clean low-frequency performance while its balanced armature array maintains rich, articulate mids and realistic upper-midrange presence. At the top end, a tia™ high driver and specially refined tia waveguide work together to produce natural, open, and effortless treble with outstanding detail and spatial definition.
One of Ocean's defining features is Passive Acoustic Control, which lets listeners physically adjust the IEM's acoustic response. Two interchangeable stainless steel tia screens control high-frequency damping, while four back-vent filters change the pneumatic loading of the isobaric dynamic drivers. Combine these adjustments with four included apex™ modules and Ocean offers up to 32 different tuning configurations, making it exceptionally adaptable to different music, equipment, and listening preferences.
64 Audio's patented Air Pressure Exchange (apex™) technology relieves pneumatic pressure inside the sealed ear canal while maintaining useful isolation. With mX, m12, m15, and m20 apex modules included, users can adjust isolation and acoustic behavior while benefiting from reduced listening fatigue and a more spacious presentation.
The Champagne Copper T6061 aluminum shells feature machined faceplates inspired by aeolian ripples found in naturally shifting sediment. Ocean also includes two premium shielded cables terminated in 3.5 mm single-ended and 4.4 mm balanced connections. Each uses silver-plated UP-OCC copper in a four-core Litz construction for low-resistance, transparent signal transmission.

FAQ Section
Q: How many drivers does the 64 Audio Ocean use?
A: Ocean uses six drivers per side in a four-way hybrid configuration: two cone-to-cone isobaric dynamic bass drivers, two midrange balanced armatures, one high-mid balanced armature, and one tia high-frequency driver.
Q: What is 64 Audio Passive Acoustic Control?
A: Passive Acoustic Control lets you physically adjust Ocean's sound using interchangeable tia screens, back-vent filters, and apex modules, providing up to 32 different acoustic configurations.
Q: Can I change the bass and treble response of the Ocean?
A: Yes. Four back-vent filters alter the pneumatic loading of the isobaric bass drivers, while two stainless steel tia screens adjust high-frequency damping.
Q: What apex modules are included with the 64 Audio Ocean?
A: Ocean includes mX, m12, m15, and m20 apex modules, allowing you to adjust isolation and acoustic behavior to suit your listening preferences.
Q: What is the frequency response of the 64 Audio Ocean?
A: Ocean has a specified frequency response of 5 Hz to 22 kHz, providing deep low-frequency extension and extended high-frequency reproduction.
