Introducing Ocean, 64 Audio’s flagship UIEM. Our new benchmark for portable high-end audio playback.

Be among the first to hear it this weekend at @headfi CanJam SoCal 2026.

Bruno Mars is on a generational run in the midst of The Romantic Tour covering almost the entire globe. Dozens of 64 Audio custom in-ear monitors are deployed throughout the stage, all the way to front of house, to ensure consistent and accurate monitoring.

Over 15 years of making products at the highest-end equips us to maximize cost-constrained designs, like Aspire 3, with flagship level technology and performance.

Commissioned by Becky G for her busy summer touring schedule, this bespoke 1 of 1 A18s features crystal clear shells, mirror silver faceplates and her monogram in gold foil.

Good design holds up to scrutiny. Great design invites it.

Lindsey Stirling continues to be one of the most physically engaging performers on her Duality Untamed Summer 2026 Tour.

Her custom A12t keeps pace with both the sonic complexity of her violin and the intensity of her performance.

No two Ripple Abalone faceplates are alike. Each is as unique as the person who wears it.

Although our Emerald Wood faceplates have been discontinued, this set is a perfect example of our faceplate department's ability to recreate the original design when your IEMs come in for service.

An exemplar flagship, Fourté is a bold statement on what’s possible in portable hifi when the rule book is re-written. Its acoustic tuning breakthroughs have subsequently flowed into all of our IEMs since 2016, and have influenced designs throughout the industry.

After 10 years of service, Fourté is being discontinued with extremely limited global stock remaining. Pick up a piece of in-ear monitor history while you still can.

Bespoke, 1 of 1, A12t CIEMs built for Mike Stringer of @spiritboxband. Pearlescent black shells, black chrome faceplates, with custom silver foil artwork.

[64 Audio @64audio]

Fourté is a four-driver hybrid UIEM, with each optimized for a specific frequency band. A 10mm dynamic driver and a direct-radiating (tia™) balanced armature driver are tuned for lows and low-mids respectively. A traditional high-mid tubeless balanced armature driver fires into the canal stem which houses the tia™ high-frequency driver.

Retro Experience - Modern Performance. This week we’re running a giveaway on Instagram where one lucky winner will end up with this Aspire 1 + WE ARE REWIND KEITH Cassette Player combo.

@SigmundTod60526 mission accomplished :)

[64 Audio @64audio]

When we use genuine carbon fiber, and not simply a similar printed pattern, you're presented with a distinct three dimensional visual depth that shifts in the light. One of our dozens of premium faceplate upgrades, each built by hand.

@twotechymates thank you!

Being the world’s first tubeless UIEM of its kind means that all four-drivers operate freely in this micro-acoustic space.

To shape the sound of these elements, Fourté forced us to explore precision like never before; each chamber milled to tight volume specifications.

The shape of these chambers, along with the use of a passive-radiator, between the shell cavity and faceplate, are responsible for Fourté’s unique frequency response responsible for its unbeatable imaging.

[64 Audio @64audio]

What began as a challenge to conventional earphone design became one of the most influential UIEMs in portable high-end audio. Fourté isn't just a flagship, it introduced tia™ and helped shape everything that followed.

To commemorate its final chapter, every remaining Fourté will include a complimentary 4.4mm Black Eight-Braid Cable ($349 value). Stock is extremely limited so be sure to get it while you can wherever 64 Audio is sold.
