Design and Build Quality
The U12t and Oracle MKII feature completely different designs. Both IEMs combine a lightweight and robust build quality with a unique, eye-catching aesthetic but use different materials for their shells and faceplates.
The U12t boasts a fresh new aesthetic for 2025. A Textured Silver Shell Color, Raised Metal Logos, and Chamfered Faceplate Bezel deliver a more elegant look and feel. At the front, you'll find the Apex ports under the chamfered 64Audio logo. Overall build quality is top-notch - the U12t feels solid in the hand and the new textured shells offer a more premium feel.
The THIEAUDIO Oracle MKII uses a resin-based shell for a robust, lightweight feel. Its shells are small and offer an ergonomic and natural fit. The Oracle MKII comes in two unique faceplate designs: Black Scarlet or Tiger - both color options pair well with the included modular cable.
Sound Signature
You're probably looking to see how these IEMs stack up on sound. We'll share our thoughts here, although keep in mind this information tends to be anecdotal and subjective.
U12t Sound Signature
The U12t features a neutral, reference-level tuning known for its accurate, detailed, and immersive sound presentation. It is the perfect in-ear monitor if you're looking to scrutinize every note and detail in your favorite music.
The bass in the U12t is well-balanced, delivering good impact and rumble when needed. Its midrange is natural and clear, allowing voices to come through with life-like clarity. Its soundstage is one of the largest you'll hear in an IEM, offering accurate sound placement for an immersive sound.
Oracle MKII Sound Signature
The THIEAUDIO Oracle MKII offers a balanced and engaging sound signature. The 10mm LCP Dynamic Driver delivers slam and sub-bass rumble with excellent clarity and control. Vocals and instruments sound natural and sit closer in the mix for a clear and detailed listening experience. The treble is well-extended, thanks to the dual Sonion EST Drivers. Cymbals and strings sound crisp and detailed without harshness.
Soundstage and imaging-wise, the Oracle MKII offers an immersive listening experience. Instruments, vocals, and other sounds are easy to pick out in the mix - even in busier tracks.
Price and Value
The U12t and Oracle MKII are priced very similarly. Both models offer exceptional sound, build quality, and aesthetics befitting their premium price tags.
The $1,999 U12t comes with a fresh new look and a generous set of accessories in the package. In the box, you get all the current Apex Modules and a pair of Pearl Premium Cables in 3.5mm & 4.4mm. You also get a selection of ear tips, a leather case, a cleaning tool, clips, and stickers in the package.
At $589, the Oracle MKII delivers exceptional value. The Oracle MKII's five-driver tribrid design features an advanced dynamic driver, premium BA drivers, and two Electrostatic drivers - a driver setup you typically only see in higher-end IEMs. The Oracle MKII also offers a robust yet lightweight resin shell with an eye-catching aesthetic. In the box, the Oracle MKII comes with a cleaning cloth, three pairs of foam ear tips, three pairs of silicone ear tips, and a premium cable with interchangeable terminations.
Our Thoughts
The 64Audio U12t delivers reference-level resolution, detail, tone, and soundstage immersion. It is the IEM to get if you want to experience your music with top-tier clarity and detail. Music on the U12t sounds clean, clear, and accurate. The 2025 version is even better - boasting an updated design and accessories package without the extra cost. You can swap out Apex Modules to fine-tune sound to your liking.
The THIEAUDIO Oracle MKII is an audiophile bargain. At just $589, the Oracle MKII delivers a clear and detailed musical experience with its balanced and exciting sound signature. While it does not have the reference-level resolution and detail of the U12t, the Oracle MKII offers a fun, natural, and energetic listening experience for a wide range of genres.
Another IEM to consider in this price range is the THIEAUDIO Hype 2. The Hype 2 features a 4-driver hybrid configuration with IMPACT2 dual dynamic driver technology for a warm and impactful sound experience.
