In this article, I review the Noble Audio Knight IEMs. The Knight features one 10mm dynamic driver, one balanced armature driver, and one Piezoelectric super tweeter. It’s priced at 289 USD.

When I first heard Noble Audio’s FoKus Apollo and FoKus Rex 5, I was impressed by how effortlessly they combined advanced tech with musicality and great-looking designs. Noble—founded by Dr. John “The Wizard” Moulton—has built a reputation for crafting high-end IEMs and headphones that not only sound fantastic but also feel distinctly special. With the Knight, they’ve taken that same innovative spirit and packaged it into something more accessible, yet still seriously impressive.

Design

Internally, the Noble Audio Knight boasts a tribrid driver configuration — 1 dynamic, 1 BA and 1 piezo driver. The DD is in charge of rendering the bass, the BA takes care of the mids and the ultra-highs are handled by the piezoelectric driver.

The Knight features pseudo-custom-shaped aluminium shells with a smooth matte black finish. The faceplates combine blue and purple hues with a layered pattern reminiscent of overlapping scales or chainmail. A Noble logo sits at the top edge of the right earpiece, while a royal crest adorns the left. The result is a design that both looks and feels premium, despite the entry-level price tag.

Although the shells themselves are average in size, the nozzles are slightly longer than usual. As a result, the IEMs might stick out a bit for some users, but in my case, the extra length actually works in my favour—I can use the stock eartips comfortably, without having to dig into my collection for extra-large third-party options.

The included cable is an 8-strand OFC braided type with a glossy black TPU sheath. It has a carbon fibre pattern on the plug and Y-splitter and there’s a metal chin slider adorned with the Noble Audio logo. It’s a good match for the IEMs and handles well without any microphonics.

Sound

Audio sources used for testing include the Shanling UA6, iBasso DX180 and iFi Audio ZEN DAC 3. The Knight is reasonably easy to drive, so you shouldn’t need to worry about what source to pair with it.

The Noble Audio Knight is a contrast of sorts. First impressions suggest an IEM tuned for musicality with a healthy dose of fun. But listen a little deeper and you’ll find there’s more beneath the surface. Audiophile qualities are present too. There’s a dichotomy between the Knight’s analogue character and its technical performance: it carries an engaging flavour, yet beneath that warmth and texture lies a capable IEM with surprising clarity and control.

Bass

The Knight doesn’t follow the usual recipe of boosted sub-bass and dipped upper bass that’s so common these days. Instead, it takes a more balanced route, with a smooth transition right into the lower mids. That means it’s not just about the rumble—you get punch too. The bass feels full and satisfying, but never bloated, with just the right amount of weight and control to keep things tight and lively.

Midrange

The Knight’s midrange is rich and emotive, giving it a velvety quality. Acoustic guitars have a woody, organic tone with full harmonic bloom, while electric guitars feel rounded and smooth without sounding veiled. The midrange captures the body of the piano notes beautifully—there’s weight and density to each keystroke, especially in the lower mid octaves. Male and female vocals both benefit from the lushness, sounding intimate and emotionally engaging, but never muffled.

Treble

The treble is well-balanced to complement the bass and midrange without sounding strident or harsh. The piezoelectric driver is fast and precise, yet free from the unnatural timbre issues that have plagued some other implementations of piezo drivers. It adds clarity to the midrange and extends cleanly, lending air and a touch of lightness that offsets the midrange’s richness.

Soundstage & Technicalities

The Knight has modest soundstage dimensions, but with well-balanced proportions of width and depth. It’s an organised stage where individual elements are easy to pinpoint and occupy their own space. Rather than everything sounding like it’s on a flat plane, there’s a sense of layering and depth. Instrument separation is solid, though micro-detail retrieval is a touch subdued, likely due to the relaxed upper treble.

Comparisons

Moondrop Blessing 3

The Blessing 3 conforms more closely to the 2019 Harman target than the Knight. It features elevated sub-bass and a leaner lower midrange, resulting in more rumble but less punch. Vocals and lower register instruments come across as thinner and less saturated on the Blessing 3. While it offers slightly better treble extension than the Knight, its micro-detail retrieval remains mediocre and roughly on par. Both of these IEMs are more musical than analytical, and either is a good option if you’re looking for an emotive, engaging sound.

Verdict

The Noble Audio Knight delivers a richness that many IEMs in this range shy away from—it’s like finally being allowed both chocolate sauce and whipped cream on your pudding after weeks of plain biscuits. Beneath the lush presentation lies a well-organised soundstage and solid resolution, proving it’s not just about indulgence. Add in the striking design and solid build, and the Knight becomes an easy recommendation—especially considering it’s Noble’s most affordable model to date.
