Introduction to the Noble Audio Amadeus review
Noble Audio – a decade ago I’d still call them a small, family-run company, yet their IEMs already showed real merit. After years of refining wired earphones, they seemed to reach a peak around 2020, not only for themselves but for the market as a whole. I still vividly remember the impression Noble Audio Onyx left on me. It was 2024, the Audio Video Show, and I happened to stop by a stand casually. After I expressed interest, a representative, who I later learned was the co-owner’s son – guided me to the Onyx. I plugged it in, and “Little Black Submarines” by The Black Keys began to unfold in front of me. When the final verse hit with the electric guitar and bass, I nearly toppled out of my chair. Until that moment I had known Noble as a small family business with nice IEMs, but it was at that point that I became hooked on their products.
As Bob Dylan sang, times are a-changin’, and we can all see that the audiophile landscape is evolving. Technology advances monthly: data transfers are faster, amplifiers more efficient, transistors smaller, batteries denser. Sixty years ago NASA had less computing power than a modern smartwatch. As technology progresses and our environments and lifestyles shift, our hobby must adapt too. Don’t get me wrong – it’s wonderful to listen to Susvara fed by a Feliks Envy from CD or vinyl, but for someone who travels frequently and works on the go, I’d love to carry a fraction of that sound quality with me everywhere. Nowadays, technology makes that possible, so why not raise our expectations of headphone makers?
I believe Noble Audio understands my requirements. They continue to develop superb wired IEMs, while also exploring new horizons in wireless HiFi gear. Their first step in this direction was Falcon, and in 2019 it was a solid product. Since then they’ve shown a variety of intriguing wireless offerings, but to be honest at the time I was relatively conservative about “audiophile” wireless gear, so I didn’t pay them much mind. Then came 2024, and they released FoKus Apollo. That headset shifted my view of wireless and more consumer-friendly audio gear. It sounds so good that it even earned one of our “Best of 2024” awards, and, to be honest, after two years it still sounds fantastic. This makes me feel that, unlike many other brands (yes, I’m looking at you, Sony, with your two WH-1000XM iterations that seem to degrade year after year), Noble Audio knows how to craft great, future-proof wireless gear.
In this short prologue, I wanted to share my expectations for today’s main star of the review: Noble Audio FoKus Amadeus. So let’s not waste any more words and dive into the review.
Packaging
The unboxing experience of the Noble Audio FoKus Amadeus is quite impressive for its price range. The box is wrapped in a red graphic sleeve that carries all the technical information. Inside the cardboard sheath, you’ll find the IEMs, a charging case, and a separate box with accessories.
The included accessories are generous: six pairs of ear tips, including regular and bi-flange options. Each type comes in three sizes, so you can easily find the best fit. In addition, there’s a USB-A to USB-C charging cable and a velour pouch. A USB-C to USB-C cable would be preferable, but let’s be honest—most of us already have plenty of those cables stashed away.
Design, Build and Comfort
Noble Audio FoKus Amadeus are available in a single colour pattern – black with red accents. The red faceplates with some swirl pattern makes the headphone design catchy, while plain black shells nicely contrasts and makes the design interesting but not too flashy at the same time. The charging case is similar to other Noble TWS cases, but thanks to the red lid it’s easy to differentiate Amadeus from the other lineup.
The build quality is great. Earphones are made of acrylic resin with milled aluminum nozzles. I’m a big fan of that combination. Aluminum provides more friction so ear tips don’t slide off the nozzle while the resin has a softer touch for ears. The comfort is great, I have no problems with application or fatigue while using Noble Audio FoKus Amadeus. The only thing I don’t like in terms of the ear unit is a tiny gap between the faceplate and the shell. It wouldn’t be a big problem, but faceplates are touch sensitive and they are the only way to control your playback. So if you don’t want to touch your phone, because your hands are covered in chalk, you tap the faceplate, chalk gets to that tiny little gap and stays there forever. Or at least I don’t have a compressor powerful enough to blow it out.
The charging case feels robust. The outer shell is predominantly aluminum, which inspires confidence in its durability. Battery life is respectable – long enough that I could use them for over 40 hours during testing without recharging. Design and build quality remain strong across the case, with one quirk: the lid is fairly thick aluminum, and closing it without Smooth Operator’s skills can be noticeably loud. If you value absolute quiet, you’ll want to snap it shut with a deliberate motion.
Tech inside reviewed Noble Audio Amadeus
Let’s start with some good old-school information about the source of the sound – drivers. Each earpiece contains a single 8.2mm custom triple layer diaphragm. It’s a dynamic driver crafted to deliver rich bass, open mids and delicately extended highs, whatever it means. What’s important, it’s capable of producing good quality sound and it’s easy to drive even with a tiny amplifier that doesn’t drain too much battery.
But as I mentioned Noble Audio isn’t afraid of modern technologies. In the modern world, true wireless headphones are expected to have some cool gimmicks. One of them is ANC and FoKus Amadeus has that feature. It’s not a mil-grade hearing protection, but it works. Earphones even in passive mode mutes the noise decently and ANC is a cherry on top to cancel some everyday noise in an office or during commuting. The only problem I have is that in a passthrough mode it introduces some weird pitch. The passthrough mode is the only area where they lose versus my main TWS – Apple AirPods Pro 2.
In terms of the tech, I need to mention the mobile app that allows you to update earphones, modify buttons behaviour and tune them to your ears. And I literally mean this. Thanks to Audiodo Personal Sound technology you can run a quick test and adjust Noble Audio FoKus Amadeus to your personal target. Some say Harman’s target is great because it’s tuned to an average person’s hearing. But for me Owczarz’s target is better, because it’s tuned to my hearing. For me, with that equalisation earphones sounds best, but for the review purposes I will describe the sound without using any equalisation.
Sound of the reviewed Noble Audio Amadeus
The sound signature is a V-shaped on the warm side of the spectrum. The performance can’t match Susvara Unveiled, but for TWS that you’ll be using during work or commuting is more than decent. What’s most important for me in daily driven TWS is the sound quality is good and the tuning is easy to digest. So let’s dive into the review.
Bass
For me, the bass reproduction is easily the standout feature of the Noble Audio FoKus Amadeus. It is deep, punchy, and while it might not quite match the stellar low end of the Onyx—which completely stole my heart – it is remarkably capable for a pair of TWS that costs a fraction of the flagship’s price. Thanks to this warm-leaning tuning, the Amadeus is incredibly fun and engaging. If your playlist relies heavily on low-end performance, you will absolutely love these. The bass response is bold, well-pronounced, and surprisingly accurate.
Listening to The Twilight Sad’s There’s a Girl in the Corner, the texture of the kick drum is almost tactile. There is a beautiful sense of reverb, and the way the decay lingers after each strike is downright hypnotizing – so much so that I found myself completely tuning out the other instruments and vocals.
That said, it is worth noting that with the default preset, the bass isn’t the fastest I’ve heard. In tracks that demand rapid-fire, precise punctuation in the lower registers, it can occasionally feel a bit pillowy or blurred. While this might pose a slight issue for fast-paced genres like metal or certain subgenres of electronic music, there are far more scenarios where this lush, lingering bass is incredibly satisfying.
Ultimately, the bass performance here is excellent, and because it can be easily tailored via the Noble FoKus app, it is versatile enough to satisfy a wide variety of sonic preferences.
Midrange
The upper-midrange of the FoKus Amadeus is slightly recessed, yet the mids as a whole pack plenty of texture and dynamic punch. Due to this dip in the frequency response, certain vocals can feel a bit less forward than expected. For instance, in The Dø’s Keep Your Lips Sealed, Olivia’s vocals lack their usual energy; they feel slightly muted and get somewhat overshadowed by the beat, which should ideally remain in the background. Fortunately, this is an easy fix – the companion app features an intuitive EQ that lets you quickly tune the sound to your liking.
On the bright side, the Noble TWS sounds far more impressive when handling lower-pitched male vocals. Tom Waits’ performance in Semi Suite feels wonderfully balanced, with the headphones perfectly capturing the gritty texture and natural harshness of his voice.
Finally, it’s worth highlighting how beautifully the FoKus Amadeus renders acoustic instruments. Listening to Rodrigo y Gabriela’s single Our Home, the acoustic guitars sound incredibly powerful. The slightly elevated lower-midrange gives the instruments a massive, rich, and highly engaging presence.
Treble
Moving up to the treble, we find a top end that is wonderfully warm yet highly detailed. While it isn’t the absolute star of the show – as the bass naturally takes center stage in the FoKus Amadeus tuning – the high frequencies are never overshadowed. In Dave Brubeck’s Blue Rondo à la Turk, the cymbals command just as much presence as the double bass; they sparkle and decay naturally without a hint of fatigue. Every high-pitched note has a way of subtly stealing your attention, pulling you deeper into the music.
At the same time, this top end can pivot to being remarkably smooth and polite, as showcased in Yann Tiersen’s La Valse d’Amélie. While every detail remains easily discernible, the vibraphone is rendered with a calm, relaxed timbre. It’s this versatility that makes the treble of the Amadeus beautifully balanced and endlessly enjoyable.
Soundstage
Finally, let’s talk about the soundstage of the Noble Audio FoKus Amadeus. Given the heavy bass impact I experienced right out of the box, I initially expected a rather closed-in presentation – perhaps something akin to the Beyerdynamic DT 770, which is known for its claustrophobic presentation and less-than-perfect positioning. How wrong I was. Once I queued up my go-to soundstage benchmarks, like Nick Cave’s To Be By Your Side or various tracks by Dead Can Dance, I was genuinely blown away.
Keep in mind, we are talking about a pair of TWS earphones here, while they are premium, they are still reasonably priced for what they offer, making the performance all the more impressive. Both the width and depth of the stage are highly commendable, and the earphones sound remarkably airy despite their warm tuning. Instrument positioning is also spot-on. In fact, if they utilized a latency-free connection instead of Bluetooth, they could easily double as an excellent gaming headset.
Comparisons
Apple Airpods Pro 2
Being deeply integrated into the Apple ecosystem, the AirPods Pro 2 has long been my daily driver. I’ve used them for years, and even with the release of the AirPods Pro 3, I still consider them to be some of the best TWS earbuds on the market. Naturally, they make for a perfect benchmark against the Noble Audio FoKus Amadeus.
When it comes to connectivity, the Amadeus allows you to connect up to two devices simultaneously and seamlessly switch playback between them. AirPods, on the other hand, can pair with countless devices, but there is a catch: they must belong to the Apple ecosystem. If you step outside of it, things get tricky – in fact, I still haven’t managed to pair my AirPods with my Windows PC. However, I can confidently say that switching between my iPhone, MacBook, iPad, and Apple TV remains absolutely flawless.
In terms of comfort and ergonomics, I personally prefer the stem-style shape of the AirPods, though I know plenty of people who absolutely despise it. For those users, the traditional, ergonomic shell of the Noble will be a much better fit. When we talk about the overall user experience, competitors can try to chase Apple, but matching them is a near-impossible task. The tiny haptic engine inside each AirPod, which delivers crisp, tactile feedback when you squeeze the stem, is simply unbeaten.
Sonically, these two are night and day. The FoKus Amadeus features a warm, engaging V-shaped signature, while the AirPods Pro 2 lean toward a safe, flat neutral. Apple’s tuning is incredibly clean, but after putting thousands of hours on them, it has started to feel a bit clinical and boring. The Amadeus offers a less universal but far more captivating sound. Lately, with both sitting on my desk, I find myself reaching for the Noble more often. They bring back that spark of excitement – forcing me to inner dialogue: “How will this track sound? Let’s find out. Sure, it’s 2 AM, but… just one more song”.
Noble Audio Amadeus review – Summary
The Noble Audio FoKus Amadeus is a compelling offering in the TWS market, successfully bridging the gap between audiophile-grade sound quality and the modern convenience of lifestyle products. Its warm, V-shaped signature can be effortlessly tailored to your personal taste and hearing via the app.
Furthermore, thanks to its commendable passive and active noise cancellation, you can enjoy that rich sound anywhere, even in noisy environments. If you are in the market for a premium pair of TWS earbuds, the FoKus Amadeus is undoubtedly one of the strongest contenders around the $300 mark.

Big thanks to Noble Audio for providing us with the Amadeus for this review. I wasn’t paid or asked to say anything good or bad about this product, all of the above is just my personal, unbiased opinion.
I’m a 24 years old software engineer, but also coffee, wine, and audio gear freak based in Cracow, Poland. I like to get lost in the city, but I hate getting lost while reading pompous audio reviews. My goal is to provide simple and informative reviews that I hope will help you to find your way around the rabbit hole.
