What's the Best Noble Audio IEM for You in 2025?

Noble is a brand that needs no introduction. They’re not the new kids on the block trying to make something flashy on a budget—Noble is the Godfather of the IEM world. Their focus is on delivering premium sound for those who demand the best of the best. Noble’s IEMs represent the pinnacle of craftsmanship and technical excellence, and if you’ve been in the audiophile game for a while, there’s a good chance you already have one of their sets in your collection.

In this article, we’re breaking down the current Noble lineup we offer—and helping you figure out which one might be the perfect fit for you.

Noble Audio Knight - $289

Kicking off Noble’s massive lineup, we have their entry-level option: Knight. Knight is a tribrid IEM featuring 1 dynamic driver, 1 balanced armature, and 1 piezo tweeter. Priced at $289, it delivers a premium feel at a budget-friendly cost. Paired with an 8-strand OCC silver-plated cable, this IEM offers excellent value for the price.

I personally enjoy the Knight most with jazz. The imaging is terrific, creating a wide soundstage that keeps you fully immersed in the music. It leans toward a neutral tuning, which pairs especially well with this genre. Jazz thrives on interplay between instruments rather than a single element dominating, and the Knight provides a clean, balanced platform that really lets that dynamic shine.

Noble Audio Stage 3 - $600

Stage 3 is Noble’s dedicated offering for live musicians. This 3-driver hybrid IEM features 2 balanced armatures and 1 dynamic driver, paired with an 8-core OCC modular cable that includes swappable terminations to fit whatever your setup requires. The shell is on the smaller side, making it a comfortable and versatile option for performers with ears of all shapes and sizes.

For stage use, accurate reproduction is everything—and that’s exactly what Stage 3 delivers. The highs are crystal clear, and the warm sound signature makes it especially great for vocalists. Stage 3 removes the guesswork when it comes to finding a premium, reliable in-ear monitor for live performance, helping musicians stay fully dialed in and focused on the music.

Noble Audio Spartacus - $1,799 

Spartacus is a 1960 Stanley Kubrick epic that—just kidding, we’re doing audio, not movies. Spartacus is a 6-driver hybrid IEM featuring 4 balanced armatures and 2 bone conductors, all housed in a composite resin body with a hand-assembled faceplate. Each unit is individually matched, and the shell is on the smaller side compared to other Noble sets, making it easier for most listeners to achieve a perfect seal. Just like its namesake, Spartacus is quick and powerful, delivering a lively, dynamic sound that pairs especially well with rock music.

Instrument separation is a major highlight here. I really enjoyed listening to Animals by Pink Floyd with this set—the drums feel snappy and tight, with toms and snares responding with impressive speed and clarity. The synths rest on top of the mix like a warm blanket, adding a layer of immersion that’s hard to put down. The air region gives instruments and vocals just the right amount of reverb extension, deepening the sense of space. Spartacus is a true warrior in the IEM world—perfect if you’re looking for something detailed, fast, and immersive. I am Spartacus!

Noble Audio Agis II - $1,799

Agis II is Noble’s newest release, unveiled at CanJam Singapore 2025. This 8-driver hybrid IEM features 6 balanced armatures and 2 bone conductors, serving as the spiritual successor to the Spartacus—with a clear focus on improved clarity, detail, and immersion. The layering on this set is excellent, making it one of the most immersive offerings in Noble’s lineup.

Agis II has a relatively balanced tuning, but its rich, thick, and lush sound signature makes it incredibly versatile across genres. I personally loved it with Shed by Title Fight. That record is dense and aggressive, with layered, crunchy guitars—and Agis II handled it beautifully. The drums sounded massive, the bass had weight, and the guitars were textured and expressive. Thanks to the excellent instrument separation, I found myself completely lost in the music.

Noble Audio Onyx - $3,200

Onyx is a quadbrid IEM featuring 1 dynamic driver, 4 balanced armatures, 2 Sonion electrostatic drivers, and 1 PZT bone conductor. It also sports a premium collaboration with Eletech, including a custom Courage 4-core cable. With a balanced sound signature and plenty of low-end presence, Onyx leans into the neutral-warm side of tuning.

What I love about a set like Onyx is how immersive it is. The clarity in the midrange really stands out—everything feels precisely placed around you, creating an experience that’s as close as it gets to being in the room with the musicians. The low end is rich and full, with the low-mids taking the spotlight more than the sub-bass. It’s a great match for classic rock with dynamic bass lines and reveals all the hidden layers in well-produced tracks. Onyx delivers a premium listening experience with a premium design and aesthetic to match. If you’re looking for an endgame set, this one makes a strong case.

Noble Audio Ronin - $3,900

Ronin is a top-of-the-line flagship from Noble Audio, built in collaboration with Eletech. It features a 7-core shielded OCC copper/silver upgrade cable and houses 8 balanced armatures and 4 electrostatic drivers. The result is a beautifully balanced sound signature that perfectly blends technical precision with a laid-back, enjoyable listening experience.

The level of detail Ronin delivers is hard to beat. In a live band setting, it truly places you inside the recording—layering is exceptional, and imaging is spot-on. Drums feel raw and real, dancing seamlessly with the bass guitar and supporting the guitars with ease. Vocals are lush and delicate, with background harmonies elevated to a level where they become instruments in their own right—revealing nuances you may have never noticed before. And let’s not forget the stunning craftsmanship of its deep blue, marble-like shell. Noble continues to nail the intersection of premium build and sound—and Ronin is no exception.

Noble Audio Shogun - $3,900

Have you ever been shopping for a new IEM and thought to yourself, “Which IEM would Uma Thurman buy?” Wildly enough, I have just the one for you. One of Noble’s newest releases, Shogun, comes in at $3,900—and its katana-esque design is a true icon of craftsmanship in the IEM world. With a warm–neutral tuning and a quadbrid build (1 DD, 6 BA, 4 EST, 2 BC), this set packs serious power into big, beautiful shells. It’s a standout piece in Noble’s already stacked lineup.

Shogun delivers impressive lows that are rich but wonderfully controlled, with the low-mids slightly forward over the sub-bass. The mids are clean and separated—every instrument shines without clashing. The highs are soft yet detailed, cutting through the mix just right. It’s an immersive, engaging listen that really shines with classic rock. And let’s be real: unplugging the termination jack feels like unsheathing a katana. How do you even put a price tag on that?

Noble Audio Viking Ragnar - $4,000

Rounding off our list of wired IEMs, we have Noble’s magnum opus: the Viking Ragnar. This set is a stunning blend of sonic excellence, technical performance, and artisanal build quality. It features a full lineup of drivers—2 dynamic drivers for the low end, 2 balanced armatures for the mids, 2 more for the treble, and 4 electrostatics for the super-highs. Housed in a Damascus-plated shell, the Ragnar is as visually striking as it is sonically powerful.

Ragnar is built for those who appreciate a hyper-technical IEM. It peels back the layers of your music, reproducing sound with jaw-dropping accuracy. Despite its thick, weighty character, it still manages to stay delicate and refined in the upper registers. With outstanding balance and precision, Ragnar stands tall as a true endgame IEM.

Wireless Options 

Noble Audio FoKus Mystique - $349

Mystique is the successor to the FoKus Pro, refining what made that set great and leveling up the wireless experience with improved call quality and stronger connectivity. It sits on the more affordable end of Noble’s TWS lineup and features a hybrid setup of 2 balanced armatures and 1 dynamic driver—pretty standard for modern budget IEMs, but executed with Noble’s signature touch. Let’s be honest: at this point, pretty much everyone owns a pair of TWS earbuds. And we all know which pair dominates—AirPods. They’re the kings of convenience, especially for Apple users. But here’s the real question: for just $100 more, can you upgrade your experience to something truly audiophile-grade? Short answer—absolutely.

With Mystique, you're not just buying another wireless earbud. You’re stepping into a world where sound quality actually matters. You’re trading in generic audio for a rich, detailed, and customizable listening experience. Thanks to the custom EQ in the Noble app, Mystique can be whatever you want it to be—from bass-heavy to reference flat—with just a few taps. It's a major upgrade in both sound and style, and a worthy option if you’re ready to move on from your everyday AirPods to something that truly delivers.

Noble Audio FoKus Rex5 - $449

Coming in at $449, the Rex5 is arguably the most popular model in Noble’s TWS lineup. It features a tribrid driver setup with 1 dynamic driver, 1 planar, and 3 balanced armatures, delivering a true HiFi experience on the go. With its detailed sound and immersive feel, it’s tough to beat—especially with a tuning that plays it safe in all the right ways, making it appealing to a wide range of listeners.

The low end is powerful and engaging without overpowering the rest of the frequency range. The mids are rich and textured, offering great imaging and layering, while the treble is front and center, delivering lush and delicate vocals. A crisp and airy top end ties it all together, making this a well-balanced IEM that suits both casual listeners and audiophiles who finally have a TWS set worth getting excited about. Pair all that with seamless app integration and EQ customization, and it’s no surprise we can’t keep these on the shelves at Bloom.

Noble Audio FoKus Prestige - $599

Looking for a basshead IEM for on-the-go listening? Prestige has you covered. It features a single dynamic driver and two balanced armatures, tuned with an emphasis on the low-end and a forward treble region. The result is a powerful, thick sound with excellent separation—seriously giving TWS sets a run for their money. Not to mention, the build quality is other worldly, each set was hand carved out of wood! 

This IEM really shines with hip hop, especially with those massive, rich, and satisfying 808 slams. I also spent some time listening to the all-time classic Dark Side of the Moon by Pink Floyd, and was impressed with how good it sounded on this set. The imaging felt next-level, and the airy, lush guitar leads were gorgeous. Prestige strikes a great balance—it delivers strong low-end impact without overpowering the mix, making it a surprisingly versatile option for a bass-focused IEM.

Noble Audio FoKus Apollo - $649

Last up in our Noble IEM guide is… a wireless headphone? Apollo combines a dynamic driver and a planar driver in a lightweight build, with balanced tuning and a seamless UI that make it a true king of versatility.

Honestly, I think the Apollo is my favorite wireless product we carry. It just does everything well — and that’s not something you get with every wireless set. The tuning leans on the safer side, which actually plays nicely with all the detail and imaging this set delivers. It’s probably the lightest wireless headphone you can get your hands on, making it a great pick for HiFi convenience on long flights. Whether you’re adding it to your own collection or gifting it to someone new to HiFi, the Apollo is a premium wireless set that hits the mark across the board.
