In this article, I review the Noble FoKus Amadeus TWS earbuds. The Amadeus features a custom 8.3mm triple-layer diaphragm and a striking red colourway. It’s priced at 329 USD.

Design
Finished in a striking mix of crimson red and black, both the Noble FoKus Amadeus earphones and charging case stand out visually. The faceplates on the earphones are made from red celluloid that shimmers under light, with a Noble Audio logo embedded within. The glossy black resin shells look and feel premium, and overall, the build quality is solid.
Thanks to their pseudo-custom shell design and smooth, rounded surfaces, the Amadeus IEMs sit comfortably in my ears. Just like with the FoKus Rex5, Noble includes a generous selection of eartips in the box—a detail more brands should take note of, since a proper fit and seal are crucial for getting the best sound and ANC performance.
Noble FoKus Amadeus: Key Features
The FoKus Amadeus runs on Qualcomm’s QCC3091 chip and uses Bluetooth 5.4, so you’re getting stable connectivity and low-latency playback. It supports SBC, AAC, aptX Adaptive, and LDAC as well, so whether you’re watching videos, listening to music, or gaming, the sound quality is covered.
At the core of the Noble Amadeus is an 8.3mm custom triple-layer diaphragm dynamic driver. Noble says it’s been tuned to deliver an expressive and detailed sound without veering into clinical territory. I’ll go over how it actually sounds down the page.
Just like the FoKus Rex5, the Noble Amadeus comes integrated with the Audiodo Personal Sound hearing calibration software. This builds a personalised sound profile based on your hearing, and is easy to set up using a simple hearing test.
Battery Life
With ANC switched off, you can get up to 12 hours of playtime from a single charge—or around 8 hours with ANC on. The case holds enough juice for roughly 2.5 extra charges, giving you up to 42 hours in total. There’s also fast charging onboard, so a quick 10-minute top-up nets you around two hours of playback. Add to that the auto power-on/off and the snug, secure fit, and the Amadeus is well-suited for all-day use.
Noble FoKus Amadeus: Mic and Call Quality
The mic and call quality are good. Voices aren’t overly compressed or thin, and the level of articulation is great. These are perfect for calls and video conferencing. Here’s an example:
Noble FoKus App
The phone app is basic but functional. With the app, you can check the battery levels, choose preset or custom EQ modes, set the active noise cancellation mode (On / Off / Ambient), customise the touch controls and update the firmware.
Sound
In this section, I’ll do my best to describe the default sound out of the box. However, I’d like to point out that the FoKus Amadeus responds really well to equalisation, whether it be the presets, a custom EQ or the Audiodo personal profile (the Audiodo profile can also be used together with EQ). In other words, the Amadeus’ sound is highly customisable and maintains excellent quality regardless of the selected sound profile.
At first, I had some reservations about the 8.3mm driver and didn’t know how it would deliver when it came to bass impact, but it turns out there was no need for concern because there’s more than enough bass on hand. And like I said, the FoKus Amadeus responds well to EQ, so you can increase the bass for more authority or attenuate it for more fidelity as you wish. It’s textured and speedy enough that it maintains control, even when boosted with EQ.
The midrange has a warm yet articulate character, but more importantly, it sounds natural and cohesive. Vocals are forward and vibrant, while instruments come across as lifelike and convincing. Things opened up even more after I set up my Audiodo personal sound profile—actually, it’s the first time I’ve gone through one of these software tuning tests and ended up keeping the profile active.
No matter which sound profile I used, the FoKus Amadeus delivered a vibrant sound with a well-balanced mix of warmth, clarity, and energy. The treble in particular caught me off guard with its crisp definition and precision. It also extends well and carries a good amount of air, which opens up the soundstage and adds detail—without ever crossing into harshness. Even on brighter EQ settings, the treble remains relatively smooth.
Comparison
Noble FoKus Rex5
The FoKus Rex5 and Amadeus share some similar qualities, such as their bold yet controlled energy and clean, contrasted notes with great instrument separation. Both offer the same feature set and customisation options via the Noble FoKus app.
Where the FoKus Rex5 pulls ahead is in its slightly better ANC and stronger technical performance. It offers improved resolution and detail retrieval compared to the Amadeus. Furthermore, the Rex5’s bass has better extension and a more tactile, physical quality that adds extra weight and depth to the low end.
Both are outstanding in their own way—the Rex5 excels at clinically dissecting every part of the music, while the Amadeus produces a warmer, more organic presentation. Either way, you’re getting a class-leading TWS in its price bracket.
Verdict
The Noble FoKus Amadeus brings a lot to the table—stylish looks (as long as you’re into red), solid build quality, and great comfort. With strong battery life, a rich feature set, and plenty of customisation through the app, it covers all the practical bases too.
While it might not reach the same level of technical finesse as the Rex5, it comes in at a friendlier price and, in my opinion, stands out as the best TWS option I’ve heard in this range. Noble continues to impress in the wireless space, and the Amadeus is another strong release. It easily earns our Recommended award.
