Noble Audio Kaiser 10

Comparisons

Jerry Harvey Audio JH13 Pro FreqPhase ($1099)

The JH13 Pro has bass that’s just a bit stronger than that on the Kaiser 10, although it doesn’t have that unique ‘hidden’ element that the Kaiser 10 bass has. The JH13 Pro bass is always there, and always strong. Overall, the Kaiser 10 might have bass that’s actually better, depending on your preferences. Detail and timbre- good signs of quality- are better on the Kaiser 10, but decay and bass tightness goes to the JH13. The biggest difference between the two, however, lie in the subbass. The JH13 has much better slam and extension in the lowest registers.

Where it comes to the mids, you already know that the Kaiser 10 bests everyone in this shootout, but the JH13 at least comes near on the evenness of its mids (near, but no dice). Timbre is also pretty good on the JH13 though the Kaiser 10 is clearly better. In every other aspect, be it energy, airiness, detail or clarity, the Kaiser 10 takes home the prize, and it’s not close.

The JH13 doesn’t do well in the treble, with poor smoothness, sparkle, and clarity. On the other hand it just so happens that these are exactly the treble traits where the Kaiser 10 does best- better especially with smoothness and sparkle, but still very good on treble clarity. Overall, the Kaiser 10 also has a treble that sounds more natural and has better extension than the JH13, though the speed on the JH13 treble is just slightly ahead.

On the other hand, the JH13 was pretty revolutionary with its FreqPhase-bestowed imaging abilities, and it pulls cleanly ahead of the Kaiser 10 in this regard. The separation across the breadth of the stage is not a strength with either IEM, but where it comes to depth and center image, the JH13 is convincingly better. In terms of soundstage size, both are quite similar, although the JH13 is taller than wide (which is kinda rare), and the Kaiser 10 is the opposite (much more common among IEMs). The JH13 however has better soundstage airiness overall.

Finally, where it comes to general qualities, the tables are turned. The Kaiser 10 pulls ahead in every single metric, with the biggest difference coming in terms of musical balance. The Kaiser 10 is very harmoniously tuned, whereas the JH13 has treble that’s a bit too hot and mids a tad too recessed- actually, let’s just call it a bit too v-shaped. Note thickness is also quite obviously better on the Kaiser 10. Whereas the JH13 has notes that are a bit thin, the Kaiser 10 has nice, thick notes- not quite the absolute thickest, but certainly among the top.

 

Lear Audio LCM BD4.2 ($1290)

With dual-dynamic bass drivers, the LCM BD4.2 has really authoritative bass that can move good air, and I honestly don’t think that a BA IEM would be able to go toe to toe with it- but the Kaiser 10 comes close. While it loses slightly on authority, the Kaiser 10 does possess better bass timbre and bass detail. Bass timbre and detail doesn’t naturally convey advantages to either BA or Dynamic bass drivers, so I take this as a very positive sign for the Kaiser 10. The LCM BD4.2 clearly pulls ahead on traditional areas of strength for Dynamic drivers- clocking in with more natural bass decay, as well as stronger and more extended subbass. On the other hand the Kaiser 10 does better on areas of strengths for BA bass drivers, having tighter bass and much faster bass speed. Overall though, I rated the LCM BD4.2 ahead.

Mids-wise, the game is closer. The LCM BD4.2 actually has better clarity and simply flawless evenness of energy, but comes in behind in terms of detail, timbre, airiness and mids energy. The LCM BD4.2’s mids were actually one of my favourites, but it lacked the all around excellence of the Kaiser 10’s midrange. For example, the Kaiser 10 scored consistently well across all the mid-range factors that I rate, but the LCM BD4.2’s airiness in particular was merely ‘above average’. The sound on the LCM BD4.2 was clear and distinct, but didn’t quite float on a cloud around your ear. It isn’t heavy, mind, it just doesn’t quite have wings.

I give the treble to the Kaiser 10, just by a hair. Before we get there, I must applaud the LCM BD4.2 for possessing one outstanding trait where it comes to the high notes- treble clarity is amazing, far better than on the Kaiser 10. BTW, that’s really more of a reflection of how good the clarity is on the LCM BD4.2, than a slight against the Kaiser 10. The LCM BD4.2 also manages to match the Kaiser 10 in terms of treble smoothness, which was an area of strength for the Kaiser 10. It has a tiny bit less sparkle than the Kaiser 10, though. Extension is also slightly poorer on the LCM BD4.2, but, and here we finally get to why the LCM BD4.2 eventually lost the treble race, the speed and naturalness on the treble of the LCM BD4.2 is really just average. I don’t mean ‘average for a TOTL‘. I really mean average. The Kaiser 10 is so much better in just these two categories, that it more than makes up for all the plus points of the LCM BD4.2’s treble.

The soundstage on the LCM BD4.2 is wider, deeper and taller. It is also much airier. For soundstage presentation alone, the LCM BD4.2 is hard to beat, and the Kaiser 10 is not up to the task. It’s not all bad, though. The consistency of the sound diffusion on both IEMs is pretty much on par, and I actually found that the LCM BD4.2 didn’t perform all that well in terms of depth imaging and center imaging- in fact, it did worse than the Kaiser 10. Where it came to separation in terms of breadth, though, the LCM BD4.2 really did a marvelous job, far outperforming the Kaiser 10 in this regard- wonderful, pinpoint accuracy of instruments across the left-right pane of the soundstage.

Wrapping up the comparison, the general qualities of the LCM BD4.2 really aren’t bad. The Kaiser 10 comes so far ahead in two areas, though, that this comparison ends up not being all that close. First, the Kaiser 10 has brilliant musical balance, but you already knew that, and the LCM BD4.2 is merely ‘very good’. Second, the Kaiser 10 has very good, thick and lush notes, whereas the LCM BD4.2 has very thin notes that really lack the satisfying richness I expect in a TOTL. In the other traits, though, it’s all pretty close. PRaT is very good on the LCM BD4.2, although the Kaiser 10 is just a bit better, whereas note articulation and distinctness, as well as musical resonance, are all slightly better on the LCM BD4.2.

 

Spiral Ear SE5 Ultimate ($1800)

Bass goes to the SE5 Ultimate. Most obviously, sub-bass is not a strength of the Kaiser 10, and it shows up in the comparison with the SE5 Ultimate. It’s not really that the SE5 Ultimate is strikingly better; rather, it does rather well for a Balanced Armateur in terms of low-end extension and sub-bass slam; whereas the Kaiser 10 is rather typical for a similar type of driver- that is, not all that good. The SE5 Ultimate also has fantastic bass decay, rivaling the Dynamic drivers in this regard- quite a surprise I must say- whereas the Kaiser 10 falls short. Finally, the SE5 Ultimate also has better bass speed and marginally better timbre and tone. All is not bad, however. I rated authoritativeness and tightness- both important for an enjoyable toe-tapping time- in favour of the Kaiser 10, and bass detail (a good indication of technical quality if any) is also in its favour.

The tables are flipped for the mid-range. The Kaiser 10 bests the SE5 Ultimate in every single facet, save for one standout trait that the SE5 Ultimate has- I’ll get to that later. Mids energy, evenness, and timbre, all important traits for a properly emotional experience, are in favour of the Kaiser 10 (although the two are quite close on evenness). In the technical aspects, clarity is just slightly better on the Kaiser 10, although detail is clearly, markedly, in favour of the Noble Audio IEM. As for the SE5 Ultimate’s standout trait, it has mid airiness that is second to none. Amazing air and lift in that midrange- much better than on the Kaiser 10.

Treble is really, really, good on the SE5 Ultimate. One caveat, though- if you’re the type who likes your treble hot and spicy, then look elsewhere. The treble here is not about heavy-handed sparkle, and in that respect the Kaiser 10 does better. Rather, there is flawless clarity and naturalness- wonderful quality– and the Kaiser 10 simply cannot compare in these areas. The Kaiser 10 also has rather smooth treble as it is, but the SE5 Ultimate is even better. You won’t get any fatiguing or piercing sibilance here. Finally, in the more technical aspects, treble speed and extension are all significantly better on the SE5 Ultimate.

Ah, space. The final frontier. These are the voyages of the Spiral Ears SE5 Ultimate. Buckle in, because you’re in for a spatial treat with these. You already know that the Kaiser 10 does not excel in this regard; well, the SE5 Ultimate does. Soundstage size is bigger in all dimensions on the SE5 Ultimate- depth, width, height. The consistency of diffusion is also a real delight on the SE5 Ultimate. If you’re not sure what this means, imagine your favourite classical band playing in Carnegie Hall (or any proper concert hall, really), vs playing at an open-air concert. The “Carnegie Hall” experience is what I’d call proper diffusion, and the SE5 Ultimate has it in spades. The Kaiser 10 is okay- but the SE5 Ultimate is just so good, it isn’t really close. It helps also that the SE5 Ultimate has good airiness and spatial cues across its soundstage, although here its lead on the Kaiser 10 is much smaller. But the biggest difference between the two IEMs is probably in the imaging. The SE5 Ultimate excels across the board, doing an amazing job with depth layering, separation in a 2D plane, and forming a centre image. Comparing the two in terms of imaging really shows out how the Kaiser 10 actually images pretty poorly for a Top-Of-The-Line.

Finally we wrap up with the general qualities. The Kaiser 10 retains its crown as the king of harmony and balance in its frequency response; although the SE5 Ultimate comes very close indeed. PRaT is almost too close to call- both are good- but the SE5 Ultimate nudges ahead in a photo-finish. More clear-cut, the SE5 Ultimate has beautiful note articulation, with each note coming across as clearly formed, distinct and present- much better than the Kaiser 10. The SE5 Ultimate also has much better musical resonance, with the sound of each note being lifted and extended gently, while the Kaiser 10’s resonance is merely above average. Finally, the Kaiser 10 has rather nice thick notes, making music sound slightly creamier than on the SE5 Ultimate.

 

Noble Audio Kaiser 10

 

Summary

Noble Audio set out to build an all-rounder, and I’d say they succeeded. All across the board, the Kaiser 10 seems to have taken the hippocratic oath- first and foremost, do no harm. At the same time, it has some standout traits. That midrange is fantastic and, for my money, will probably make fans out of most of the music-loving world. Like a perfectly seasoned dish, the harmony and balance of the frequency response on this IEM are also top-notch. But the Kaiser 10 is not perfect. If you’re the type who loves me some good soundstage; imaging; or sub-bass; this IEM won’t cure your malady. Which malady, you ask? We audiophiles call it upgraditis…

Pros: Treble that achieves the rare duolity of being both sparkling and smooth; world-class midrange; amazing harmony in frequency response; and authoritatitive yet detailed bass

Cons: Spatial qualities- both soundstage and imaging- could be better. Sub-bass slam and extension also does not rate well

Overall Score: 82.1 (Outstanding)

  1. Interesting… I would have expected it to rank higher!
    I agree with your assessment (for info I have K10 and SE5, but Reference.) The K10 are solid but I’ve always found they lacked the magical musicality of SE5. (In your terms this magic could be soundstage + imaging + airiness + musical resonance.) The K10 sounds like music comes from a wall and for me this limits my enjoyment.
    The vocals are surely top-notch and the most impressive part is the timbre: drums, for example, are spot on. It is not perfect though, because sometimes it sounds like the singers (esp. female) slightly pinch their nose. Treble are super-smooth, but I regret that they lack air and sound a bit plasticky.
    However I find bass better than you suggest. It might not the deepest but the air it moves provides a nice compensating feeling. I’d also like to add that the fit is exceptional, much better than my SE5 and UM Merlin.

    A few things remarkable on SE5 Ref vs K10, and it might also be the case for SE5 Ultimate: the super dark background; the texture; the density of instruments (I find the sound has much more weight on SE5Ref, esp. the bass kick harder on SE5 Ref than K10); the treble floating around you; the instrument separation.

    Looking forward your take on the next one!

    • the same thing about roxanne ,built the wall of sound is not good thing indeed
      But why there is no review of Flare r2 pro ,it sound very good and better than my th900 .
