64 Audio

Introducing 64 Care Plan. At the time of designing/purchasing your CIEMs, you'll now have the option of purchasing a two year extension to the warranty with greatly increased coverage: -Four Total Years -Unlimited repairs -Two remolds -& more Learn More: bit.ly/4cmb2eQ

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.

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 :)

@64audio These are cool, that's all I have to say they are cool

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!

@64audio looks nice

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.

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.

Your eyes may only be drawn to the maple burl faceplate, preserved in acrylic. Yet this A12t is a combination of wood, metal, copper, and acrylic—materials shaped by nature, refined by human hands, and intentionally arranged in pursuit of performance and beauty.

A century of recorded music, always within reach. Experiencing it as if you were there simply requires the right way to listen. That's why U12t remains our most popular UIEM in its tenth year of production.

@SigmundTod60526 Thank you. The tuning is neutral/warm. A18s is a 4-way 18 driver IEM with 8 ported low ba drivers (using an electronic LPF), 8 low-mid BA, 1 high-mid BA, and 1 patented direct radiating BA (Tia driver).

@64audio I'm not gonna lie this may be the most punk rock iem I've ever seen, what's the tuning look like? And the drivers? Is the cable modular or can you buy either? So many questions

Spring is in full bloom, and this custom A18s is a year-round reminder of its beauty.

High-quality audio is no longer just an option, it’s becoming an expectation. As streaming platforms adopt lossless audio and thoughtfully designed sound systems become more common in public spaces, expectations around music reproduction continue to evolve. Music deserves to be faithfully reproduced.

@64audio Yes!

Real live flowers preserved forever in crystal clear acrylic. Each placed and arranged beautifully by hand. Who thinks we should make this a standard option? 🙋‍♂️
