I test audio kit for a living, and these earbuds' death-proof battery and regal design blew me away

Noble FoKus Amadeus: Two-minute review

Can earbuds make you feel like royalty? Well, Noble Audio are here to give it a good old college try with their Noble FoKus Amadeus earbuds; the latest and cheapest in the FoKus series, but which benefit from some posh new engineering in both soft- and hardware. Specs-wise, these true wireless ‘buds knock it out of the park with LDAC and aptX Adaptive Bluetooth connectivity (other codecs are available), customizable sound profiles and an extensive battery capacity I actively struggled to exhaust during review.

Sound is the primary reason to buy something like the FoKus Amadeus – and these do sound great, with a cushy low-end and plucky transient response that makes for a playful listening experience straight out of the box. But these earbuds’ ergonomics are almost more noteworthy than their fidelity. Noble’s expertise in custom IEMs shows, with an asymmetrical design that follows the contours of the average ear canal better than any other generic-fit ear-thing I’ve tried. A glut of spare and swappable ear tips seals the deal with a thoughtful kiss.

These earbuds are only really let down by a lacklustre ANC, which is far from best-in-class – though their stock sound profile could be a little divisive, too, depending on your taste. That said, this writer found them to auditorily succeed exactly where they promise to, and even exceed expectations in other areas. If you’re looking to put some serious money behind a serious set of the best high-fidelity earbuds out there, these are very likely the earbuds you seek.

Noble FoKus Amadeus: Price and release date

• Release date: June, 2025
• Price: $320 / £299.99 / approx. AU$615

Noble sits pretty at the cutting edge of the in-ear monitor (IEM) market, with a suite of four-figure products that are as much to look at as they are to listen to. Noble’s custom IEMs are rightfully lauded for the incredible attention to detail they possess in practically every sense. With the recent FoKus series, Noble offers that rarefied approach to quality audio at a (slightly) more palatable price.

Indeed, the Noble FoKus Amadeus (the brand's latest offering) are clearly designed to evoke a different form of rarefied quality, often ascribed to classical music. If the presence of “Amadeus” in the name (for Falco Wolfgang Amadeus Mozart, no less) wasn’t enough, look instead to that regal red finish on the earbuds. It's at once a refined finish in its own right, as well as a subtler nod to the firebrand composer via his oft-painted tailcoat. These surface-level signifiers are here to guide your thinking on the Noble FoKus Amadeus’ guts, too, where Noble has aimed to “[blend] classical artistry with contemporary engineering”. Rich stuff indeed.

The FoKus Amadeus wireless earbuds retail for $320 / £299.99 / approx. AU$615, putting them firmly above the peloton as far as the average earbud is concerned. That retail price does, however, make these the cheaper earbuds in Noble’s FoKus range, and hence the most accessible in Noble’s entire premium-quality oeuvre. Still, for your money, you’re buying a rarefied piece of portable kit, with multiple modes of Bluetooth connectivity, 42 hours of out-and-about-iness and a considered approach to conveying your faves ear-ward.

Given the highly competitive entry-level price band some dozens of dollars below, this price could be a bit rich for some consumers’ blood – but Noble Audio does an excellent job of justifying their expense, in theory and in execution.

Noble FoKus Amadeus: Features

• Excellent Bluetooth connectivity
• Exceedingly decent battery life
• Shame the ANC isn’t great

The key audiophilic selling point for Noble’s latest buds is the new driver design. The Amadeus sport a single triple-layer diaphragm driver per earbud, utilizing three skins of different materials – ceramic, titanium and PEEK – for enhanced frequency control. This commitment to single-driver superiority is backed-up by a holistic approach to audio excellence; there’s multifarious Bluetooth 5.4 connectivity, with support for SBC, AAC, LDAC and aptX Adaptive codecs.

While this driver's sound profile is great out of the box (more on which later), there are extensive EQ-fiddling opportunities in the Noble FoKus app, which is a pretty sweet one-stop shop for controls and customization. As well as graphic EQ bands, curves and presets, you’ll find a nifty Personal EQ algorithm, courtesy of algorithmic boffins Audiodo. Complete a short hearing calibration process, and you get a fully personalized sound profile with which to enjoy your investment all the more.

The Amadeus purport to provide three different listening modes: standard listening, ANC, and an Ambient mode which boosts the sound of the outside world for safer public groovin’. These features can be accessed and toggled via the aforementioned Noble FoKus app, or more readily via the Amadeus’ dual-bud capacitive-touch control capabilities.

Unfortunately, the latter two modes leave a little to be desired. I was willing to make concessions for the ANC mode when testing it on a loud rush-hour bus, but even in my quiet living room, it did little to quell incidental sounds from elsewhere. The Ambient mode possesses quite a high noise floor, too, which naturally proved a little distracting at times.

All that said, these earbuds do an excellent job of passive sound isolation anyway, so I didn’t really feel additional noise cancellation to be necessary. For the Ambient mode, sharp and loud sounds cut through any music with remarkable fidelity – fundamentally, I’d rather suffer a hissy soundtrack and not get hit by a car, than the opposite.

Lastly but no less importantly, the Amadeus offer up to 12 hours' continuous battery life in one sitting – and up to 42 hours using the charging case (thus outliving mayflies, but that's only part of the story, as I'll explain). It’s never easy to estimate what on-paper battery-life specs mean for real-life usage, so let me say this: outside of early days review-related stress-testing, these earbuds made it through six weeks of casual everyday usage on a single full carry-case charge. If that’s not enough for you, a 10-minute charge will gift you two hours of playback. You’ll never be caught short with these.

Noble FoKus Amadeus: Sound quality

• Broad, comfy, forgiving low-end
• Transients and dynamics handled marvellously
• Customizable sound profiles

For the majority of my time with the Noble FoKus Amadeus, I elected to listen at their stock, undoctored best, reserving the ‘calibrated’ experience for after I’d gotten a feel for what exactly they’re aiming for. In a nutshell, I can describe what they aim for as ‘presence’.

They lean warm and cushy, giving you a real solid base of bass to lean on; that warmth is a great foil for the pluckier high-end, which shines when handling percussive brilliance. Gelli Haha’s Bounce House is a catchy piece of slant-pop ear candy and all the more, er, moreish for the combination of speedy transient response and supple low-end on display. It's a great primer for these earbuds' capabilities out of the box.

The Amadeus landed on my desk around the same time I discovered the discography of 1970s American soul underdog Leroy Hutson, who replaced Curtis Mayfield in The Impressions. As such, quintessential DJ-fodder albums like the eponymous Hutson were frequent listens through the Amadeus’ smoooth-with-three-‘o’s drivers. Standout fave and stone-cold banger Lucky Fellow is resplendent in its tactile width. Hard-panned percussive guitars, leaping dynamic drums and fulsome, reedy vocals-in-harmony are all presented at their level best

Moving on to less-novel territory, one of my more common tester albums is Queens of the Stone Age’s Songs for the Deaf. This is a record I have known inside-out and back-to-front since its 2002 release, and which hasn’t lost a speck of luster in all 13 intervening years (because it is absolutely 2015 right now, Bowie’s absolutely still alive, and I am absolutely NOT an ancient fossil of a tech reviewer).

I’m pleased as punch to report that, through the FoKus Amadeus earbuds, this benchmark album still very much punches me in the face with urgent snares, sausage-fat guitars, growling bass and Mark Lanegan’s gruesome gravel-words. Again, the Amadeus' transient capabilities shine – spiky but not sharp, sudden but controlled, and in possession of a unique tactile clarity. It’s actually a bit addictive.

Nevertheless, there are some minor criticisms to be made –sometimes, energy can be a little misplaced. That plush, supple low-end can allow kick drums to take up a little too much real estate on occasion and, otherwise, can serve to cover for an occasional lack of width in the upper ranges.

Also, I did briefly test Audiodo’s sound profile calibration via the Noble FoKus app, and will say that I’m personally not a fan. The test is fun, using different volumes of tones at different pitches in each ear to develop a picture of your hearing sensitivity across the spectrum, but I found the results a little disarming first time round.

I won’t be knocking the Amadeus for featuring this algorithmic tech. I do think it’s a great thing to have – particularly as a way for people with gig-battered ears to improve the audibility of spoken voices in podcasts or phone calls. For music, though, my personalized EQ curve only served to put an uncanny mid-scooped sheen over sounds I was already familiar with and mentally compensating for. The great thing about these EQ options is exactly that: they’re optional.

Noble FoKus Amadeus: Design

• Satisfying satin-red carry case
• Absurdly comfortable in-ear fit
• Touch controls are great, but finicky to start

You don’t design a set of wireless earbuds to look like this without wanting someone to talk about it. The FoKus Amadeus are waggling their figurative eyebrows at you, and trying not to drop a monocle in the process – an image befitting something non-ironically named for a classical composer.

There’s the glossy red finish on each earbud that recalls at once a luxury guitar plectrum and a Rover 800 dashboard (a lesser-spotted Sterling 800 if you're in the U.S.) – it serves to turn your head into an oddly proportioned executive sandwich accordingly. There’s also the delicious satin-red charging case lid, which incidentally possesses one of the more satisfying clasps I ever did feel. I could open and close this little box all day long.

The Amadeus earbuds are presented so lushly that you daren’t simply drop the case in your tote bag, among your keys and other scratchy effects – and Noble thought of that too. To prevent the marring of that pleasing finish, you can slip the case into a tiny velour drawstring pouch, and feel delightfully dainty in retrieving your earbuds from within.

Striking as these are as objects d’art, it’s my view that comfort is really where these buds stand above the rest. It’s not an easy job to make something relatively substantial fit so comfortably, and yet Noble’s achieved it with more success than any other brand I’ve tried.

For one, I’m a big fan of the different eartip options, handily provided by Noble in a little plastic case for your perusal. There are three sizes of single- and double-flanged eartips respectively; I personally got on best with the mid-sized double-flanged eartips, which delivered a security of fit hitherto unexperienced in other wireless earbuds.

This level of security is aided all the more by some clever topology. These earbuds share the same design principles as moulded in-ears, with angled drivers that seek to nestle close by the second bend in your ear canal. This, coupled with a clever balance of weight above the drivers, makes for a supremely snug and happy fit.

The capacitive touch functionality on the Noble FoKus Amadeus earbuds is great, by virtue of being very difficult to engage accidentally. The control scheme, though, is a little difficult for the sheer amount of functionality there is.

Noble has tried to make this as intuitive as possible, dividing tasks between earbuds – double- and triple-tapping the left earbud controls volume, while the same actions on the right move between tracks – but this isn’t the easiest to internalize without frequent revision. Even after a month of daily use, it’s still 50-50 whether I switch ANC mode on or activate my phone’s voice assistant.

Mercifully, the Noble FoKus app enables you to customize these controls to your own liking; a small but crucial gesture, that soothes the old-man-yelling-at-cloud in me. That something so insignificant (and readily rectified) commands so much of my attention is, in fact, proof that these earbuds are probably doing something right.

• Design quality score: 5/5

Noble FoKus Amadeus: Value

• Great feature-set
• Outstrips competition
• Worth it if you’ve got it

That $320 / £299.99 / approx. AU$615 price point isn’t one to be sniffed at. The vast majority of wireless earbuds come in well below this price, as do the vast majority of soundbars, consumer-grade monitor speakers and even integrated hi-fi systems. If you’re willing to spend this much, you obviously care a great deal about your mobile listening experience and understand that spending a little over the odds is the only way to get clear of that entry-level quality trap.

With an extensive battery life and some excellent Bluetooth connectivity, the FoKus Amadeus meet the basics well. With a great build quality and reassuring carry case, there are no qualms to be had about their design either. With an incredible set of newly engineered drivers, capable of providing all the oomph and splat you could ever want on the move, their sound fidelity is quite simply excellent.

All together, these facts make for a very compelling argument as to the Noble FoKus Amadeus’ value. Still, it’s a lot to drop on some earbuds. Which is exactly why you might have noticed some heightened scrutiny, with respect to the miniature frustrations I experienced during my testing.

This higher standard is an unfortunate function of pricing something in that difficult “middle” range (which looks indistinguishable to the top shelf, from the point of view of the average, budget-conscious buyer). Such frustrations would be somewhat forgiven in cheaper earbuds, and absolutely unforgivable in a set that dared to ask for more.

Even with this nitpicky frame of review, the Noble FoKus Amadeus earbuds absolutely pass muster. And that’s without noting the various ways in which Noble have outstripped the competition at this same price range – with longer battery life, better sound and better connectivity besides. If you’re spending this much on earbuds, you’re buying these, their twee, reverential branding notwithstanding.

How I tested the Noble FoKus Amadeus

• Tested for six weeks
• Used at home and on the go
• Predominantly tested using streaming services Bandcamp and Spotify, on a Samsung Galaxy S23 smartphone

The Noble FoKus Amadeus became my daily-driver earbuds, taking up a permanent space in my tote bag for daily usage on public transport and while gallivanting about town. I streamed music from Spotify and Bandcamp mostly, via my Samsung Galaxy S23; I occasionally used them at home, too, using my HP Pavilion laptop and the same services.
