Our summary
Product Strengths
- Excellent detail retrieval, resolving with the best over-ear headphones, challenging the brain to take it all in.
- Wide soundstage with precise imaging, creating an immersive, holographic 3D image.
- Easy to drive, delivering speed and impact even with low-power sources.
- High level of craftsmanship and build quality, using premium materials like CNC-machined aluminum and Damascus steel faceplates.
- Comes with the Magnus cable, a high-quality 8-core cable constructed with graphene, monocrystalline silver, and copper-silver alloy.
Product Considerations
- Treble can become a bit hot and fatiguing over long periods, but can be mitigated by using foam ear tips.
- Bass presence is more nominal and cohesive, not dominant or overpowering like some bass-head IEMs.
- Fit may be an issue for some due to the larger-than-average size of the IEM.
- Could be fatiguing over time due to sensory overload from extreme detail.
- Some reviewers found that the upper mids/lower treble frequency range could use a little boost.
Comparisons (according to reviewers)
- Offers a stronger balance of detail, performance, and musicality, a fuller, richer midrange, and better texture and timbre, when compared to the Empire Ears Odin—Odin has stronger holographic separation, an intense sense of vocal performance, and more potential for fatigue.
Takeaway: The Noble Viking Ragnar is a top-tier IEM, offering incredible detail and a wide soundstage for an immersive listening experience. Its build quality and design are exceptional, making it a great choice for those who want some of the best IEMs in the market.

Our take on the brand
Our summary
Product Strengths
- Gorgeous IEM with a finish worthy of a top-of-the-line IEM, pictures not doing it justice
- Highly revealing, with incredible detail and microdynamics that deliver a vivid, lifelike reproduction of music
- Excellent speed and strong texture in the balanced armature based low-end
- Clean, detailed, and transparent mids with top-tier detail retrieval coupled with strong layering and separation
- Soundstage is wide and three-dimensional, with holographic imaging, giving a real sense of being on stage or in the studio with the performers
Product Considerations
- The IEM is on the larger side, so consider this if you've got smaller ears
- Ronin is bright and has energetic treble, which may not be preferred by those who like a warmer sound with bass emphasis
- Bass is more neutral, and it's not going to have the impact of a dynamic driver bass
- Treble can be somewhat unforgiving, highlighting unpleasant aspects of older or lower-quality recordings
- Some reviewers found the character of Ronin to be a little bright and sometimes bass-lite, and may need proper pairing to sound its best
Comparisons (according to reviewers)
- Vs Empire Ears Odin: Odin is more versatile, but Ronin's treble performance is at a higher level
- Vs 64 Audio Fourte Blanc: Fourte Blanc offers a more balanced sound overall, while Ronin leans towards a more technical, bright sound
- Vs Noble Viking Ragnar: Ragnar has more rumble and denser, deeper layers of bass, while Ronin has slightly higher resolution
- Vs Noble Sultan: Ronin has more details, while the Sultan is more weightier and warmer in representation
Takeaway: The Noble Ronin offers incredible detail, imaging, and resolution, delivering an immersive listening experience for those who appreciate a highly revealing sound. For those with a collection of high-resolution music who want to hear every nuance, the Ronin is an excellent choice.

Our take on the brand
Our summary
Product Strengths
- High-quality build and materials, with CNC-milled aluminum shell and Raffir composite faceplate, which gives a jewelry-like element
- Great imaging with a big soundstage, good instrument separation, and placement
- Excellent vocal imaging with a forward, intimate, and balanced vocal presence that avoids sibilance
- Deep bass extension with physical characteristics (bone conduction driver), and good texture across the entire range
Product Considerations
- Fit can be tricky due to the larger size, potentially problematic for those with smaller ears, but a deep penetration ensures a good seal with the right ear tip
- Can be source-sensitive, and might become muddy with warmer sources—more reference or incisive sources are recommended
- Bass bloom can overwhelm the mids on some recordings
Comparisons (according to reviewers)
- Vs Vision Ears VE10: The Onyx has a massive arena-like soundstage, while the VE10 feels more like a studio; the VE10 has stronger mids and more extended treble, but can be shouty
- Vs U12T: The Onyx has more focused and bodied vocals, and the bass provides better pressure and control, while the U12T has greater clarity
- Vs Aurora: The Onyx offers more precise and lively sound with better bass, and a more realistic vibration
Takeaway: The Noble Audio Onyx has a great build and delivers a unique, dark sound signature with a wide soundstage. With a good blend of bass, smooth highs, and clear vocals, the Onyx provides a great listening experience, especially for genres like rock and metal.

Our take on the brand
Our summary
Product Strengths
- Lovely tuning balance across the board, backed by a wonderfully holographic and immersive soundstage that keeps the listener deeply involved without fatigue
- Excellent channel balance from left to right, but holographic layering and cavernous presentation will engulf the listener in the presentation
- Noble Audio's hardest hitting tuning yet, with a combo of fast, physical bass, deep extension, and the brand’s signature top end detail and clarity
- Visually stunning design with intricate Japanese-themed aesthetic
- Excellent passive isolation
Product Considerations
- Slightly dark lower-treble
- The shell is sizable which could feel big in some ears, and the initial insertion might feel cumbersome
- The Shogun’s aesthetic design may be 'too much' or 'too gaudy' for some
- Bass texture might not be as present as expected for the price range
- Mids and highs could use a bit more energy
Comparisons (according to reviewers)
- Vs Noble Ronin, the Shogun has a warmer, heavier sound
- Vs Empire Ears Raven, the Raven has a deeper, stronger subbass response, while the Shogun emphasizes the midbass and low mids a little more, the Raven also adds a bit of an extra pop in the vocals
Takeaway: The Shogun is an all around great IEM that adds a little more warmth and color to Noble’s flagship lineup and stands strong among the competition. It's worth checking out if you want a balanced sounding, flagship quality IEM with hard-hitting bass and impressive spatial imaging.

- Technically very strong, with a neutral and uncolored sound.
- Excellent micro-detail.
- The mids have great transparency, resolution, and realistic timbre.
- The treble is transparent, detailed, and high-resolution, without being aggressive, thick, or thin.
Product Considerations

Comparisons (according to reviewers)
- Vs Sennheiser IE 900: Kadence's soundstage may initially seem underwhelming compared to the IE 900, but it provides transparency and clear stereo positioning.

- Wide, three-dimensional soundstage, with a strong, focused center image.
- Clarity in the midrange, with a bit of coloration that adds character, especially to male vocals.
- Treble presentation that's airy and sparkly, with the right amount of detail.
- Engaging, fun sound signature overall.
Product Considerations
- People with smaller ears might have a little difficulty getting the right fit because of the large shell.

- Some reviews say that the stock cable might be of lower quality than expected for the price range.
- The sound signature is V-shaped, which may not appeal to everyone.
- The timbre has a 'cool' characteristic, which might not be the most natural sound.
Comparisons (according to reviewers)
- Vs 64 Audio Volur, the Spartacus offers faster and more detailed bass, while the Volur has more natural bass, the Volur also has airier treble and clearer, more holographic imaging.
Takeaway: The Noble Audio Spartacus is an IEM with a fun and engaging sound that is great for people who love a lot of bass and big soundstages. It's fast, detailed, and technically impressive, making it a great choice for many music genres.

Our take on the brand
Our Summary
Product Strengths
- Incredibly balanced and engaging sound with the right amount of low-end weight and good vocal presence, making it flexible for a wide range of genres
- Natural and balanced sound, with outstanding midrange clarity and impressive coherence, making it versatile for a wide range of genres
- Excellent imaging with a great sense of accurate positioning
- Very comfortable in the ear due to the long nozzle and contoured quasi-custom universal design
- Noble’s 8-core cable always has a good feel to it, being tangle resistant with no memory
Product Considerations
- Bass and treble extension are not the most impressive in its price range
- Soundstage is not very wide, in fact, they are a pair of intimate sounding earphones
- Because it is a hybrid design, there is a fairly prominent bass vent port just to the side of the housing’s 2-pin socket, which can affect isolation
- Likely needs more sparkle and agility in the upper region to satisfy treble listeners
- The wood adds some weight, so it feels more substantial than non-Prestige Noble Audio monitors, even though it has fewer drivers
Comparisons (according to reviewers)
- Compared to the Solaris 2020, the Zephyr has better coherence and a more natural transition from mids to highs
- Compared to the Empire Ears Valkyrie, the Zephyr has a more forward vocal presence and midrange
- Compared to the Fir M4, the Zephyr has more vibrant vocals
Takeaway: The Noble Zephyr is a good-looking and comfortable IEM with a balanced and natural sound, especially in the midrange, making it suitable for various music genres. It is a great pick for listeners looking for an honest IEM that retains a great sense of musicality.
