The Noble FoKus Amadeus is a true wireless earbud featuring a 8.3 mm dynamic driver with a 3-layer diaphragm. It is the newer, less costly, sibling of the Rex5, which uses five balanced armature drivers. The sound quality is remarkably similar between the two, although the Rex5 still has an edge in some areas. The Amadeus is currently priced at 320 USD, significantly less than the Rex5 at 449 USD.
The earbuds offer a playback time of 8–12 hours on their own, extending up to 42 hours with the charging case, which also supports quick charging. With high-resolution codec support, including LDAC and aptX Adaptive, the Amadeus should deliver excellent wireless sound quality. If you’re streaming Hi-Res audio from services like TIDAL or Qobuz, you’ll likely appreciate this feature.
The Amadeus features dual microphones with Qualcomm cVc noise cancellation, as well as hybrid active noise cancelling (ANC) and transparency mode. It also supports multi-point connection, true wireless mirroring, and automatic power on/off functionality.
AMADEUS IN USE
Pairing worked flawlessly for me. I simply opened my Bluetooth settings, and the Amadeus appeared ready to connect.
There are several sizes of ear tips included, but I used my Tangzu Sancai wide bores, as they fit me better.
Once paired, you can access the Amadeus in the Noble FoKus app to customize its functionality and explore various EQ options.

TOUCH CONTROLS
The earbuds support the usual touch controls, which are as finicky in use as they tend to be on most true wireless models. It gets better when you figure out how long to tap for each tap and exactly where you should tap.
Single, double, and triple tap functions can be customized to your preference within the app. Here are the options:
- Pause/play
- Volume up
- Volume down
- Next track
- Previous track
- Pause/play
- ANC/Ambient mode switch
- Disable
There is also a long-press function that activates your device’s voice assistant. To answer a call on the Noble FoKus Amadeus, simply tap the sensor once on either earbud. To reject an incoming call, press and hold the sensor on the right earbud for three seconds.
EQ OPTIONS
There’s standard EQ functionality, with presets and custom options of various types. There’s a standard type 10 band EQ tool and a nice 3 point EQ-graph tool where you can drag dots around to create your preferred curve. You can save your own EQ profiles.
You can also create your own “Personal EQ” in the app, just like with other TWS earphones from Noble. The setup guides you through a short process where you provide feedback, allowing the app to adjust the sound according to your hearing profile.
I’ve described this process in my other FoKus reviews. Personally, I don’t find it necessary, to me the Amadeus already sounds great out of the box. To be honest, I often find these EQ features more of a gimmick than genuinely useful, though some users may find real value in them, especially if your hearing is impaired in any way.
ANC – NOISE CONTROL
I find that the noise cancelling works very well, and the ambient mode is quite nice, though there’s always a bit of background hiss when it’s enabled – as usual with TWS gear.
It’s also convenient that the Amadeus allows you to switch ANC modes by tapping the earbuds. With the Rex5, you have to change ANC modes through the app, as there’s no option to do it directly on the earbuds – even with the latest update.

LISTENING IMPRESSIONS
Here are some track-by-track impressions, using my Poco Android phone and the Qobuz app.
Inga by Maridalen
Nice soundstage and imaging, with a well-balanced tuning that leans slightly warm and sounds very natural. Excellent detail retrieval.
Yours by Bill Laurance
Rich, detailed sounding double bass, warm sounding piano with great detail.
Seven Nation Army live (..northern lights..)by White Stripes
Rich, thick bass. Well separated vocals. Great detail, instrument separation is good.
Beautiful Things by Benson Boone
I don’t really like the production of Boones albums, but the Amadeus makes this track sound better than with most earphones I’ve tried.
The Sun Always Shines on TV MTV Unplugged by a-ha
Excellent vocals timbre: smooth, warm and natural. The presentation is very well balanced and coherent. Impressive.
Come Away With Me by Norah Jones
Again, the tuning is very well balanced. The bass, which can often be overpowering, is now perfectly controlled. Vocals—sometimes too forward on other setups—sound natural and smooth with the Amadeus, yet retain excellent detail and nuance. The piano is pleasantly crisp without being aggressive, as it occasionally can be.
Limit to Your Love by James Blake
Excellent vocals timbre: natural, nuanced and refined. The massive bass is authoritative and full but not bloated.
Rocket Man by Bob James Trio
The double bass is on the more powerful side, but everything is nicely rendered. It’s slightly warm sounding in a natural way.
Never Enough by Loren Alred
Another track that often sounds terrible on many earphones but the Amadeus manages to make it sound good. The vocals are natural and not as glary as they can be on many other earphones.
Maple Noise by Greene Serene
A very dynamic jazz improv — it sounds excellent. The tonal balance is impressive, the dynamics are great, and the soundstage is quite good.
Summer 3 Vivaldi Recomposed by Max Richter
Excellent instrument timbre, great layering. A very coherent presentation of a complex track.
Mahler’s Symphony No 2 III by Paavo Järvi
This track sounds very nice, though the volume doesn’t get quite high enough. That’s a common issue with TWS earbuds and can vary from phone to phone.
Like Suicide by Soundgarden
The bass is full bodied, guitars are nicely layered, and there are warm nuanced vocals.
Spontaneous Compositorius by Thomas Agergard
Smooth, warm-leaning saxophone, accompanied by clean, liquid-sounding percussion that’s never overly crisp. The bass is rich and full-bodied — powerful yet well-controlled, making its presence felt without being too overwhelming.
WRAPPING IT UP
Sound Signature
The Amadeus has a warm sound signature, featuring full-bodied but controlled bass, smooth, warm mids, and pleasant, non-fatiguing highs.
Treble
The treble is clean and delicate, never overly crisp or aggressive, instead sounding smooth and slightly laid-back.
Midrange
The midrange is slightly warm and nicely smooth, full of nuance, but above all, it sounds very natural. I particularly appreciate how it handles less-than-perfect recordings.
Bass
The bass is fairly powerful but generally not overpowering. Occasionally it can be a bit too strong, and in those cases, it’s nice to have the EQ option to apply a negative bass shelf.
Soundstage and Imaging
The soundstage is quite good, though not spectacular. The imaging is relatively intimate, yet instrument placement is well-defined. Above all, I’m impressed by how coherent everything sounds.
Detail, Dynamics, and Timbre
The overall detail level is very good, though it’s presented in a nuanced and refined way rather than pushed upfront. Dynamics are strong, but the presentation leans more toward smoothness and warmth than crispness and sharp articulation. The Amadeus isn’t an analytical IEM — it prioritizes musicality and a natural timbre.
COMPARISONS
Noble FoKus Rex5 vs Amadeus
The Rex5 has a more energetic treble, with stronger detail articulation, making it less smooth and laid-back. Its midrange is also crisper and more defined. The bass remains powerful but is slightly less so, offering better texture and definition. The soundstage feels a bit less intimate, with slightly stronger imaging.
In short, the Rex5 is generally a bit crisper and more upfront, leaning toward a slightly more analytical presentation with more articulate detail.
The differences between the two aren’t huge in absolute terms. You can read my full Rex5 review here:

CONCLUSION
The Noble Audio FoKus Amadeus is an excellent-sounding wireless IEM with a warm-leaning, pleasant sound signature. It delivers plenty of detail, and the imaging is excellent for TWS earbuds. While I was very impressed with its big brother, the Rex5, the Amadeus might be even more appealing. It falls slightly short in terms of detail, but personally, I prefer the warmer tuning of the Amadeus.
The Noble Audio FoKus Amadeus comes highly recommended.
