Noble Audio FoKus Amadeus: The Mozart of True Wireless

The true wireless earbud market is bursting with options—from feature-packed giants like Sony and Sennheiser to boutique audiophile brands. Yet Noble Audio consistently stands out with its uniquely tuned FoKus series, marrying reference-level tuning with wireless convenience. With prior hits like the Mystique, Prestige, and Rex5, the bar was already high. Now, Noble introduces the FoKus Amadeus—a stylish, Mozart-inspired TWS designed to bring a rich, musical experience without sacrificing flexibility or modern features. But how does it truly perform? Let’s dive deep.

What’s in the Box

• Noble FoKus Amadeus True Wireless Earbuds
• Matte black charging case
• Assorted silicone ear tips (various sizes)
• Carrying pouch
• USB-C charging cable
• User manual and warranty card

Noble includes all the necessary accessories to ensure a personalized and comfortable fit. The varied ear tip sizes cater to different ear shapes, maximizing both sound isolation and low-end response, which is especially important for accurate bass delivery in in-ear monitors.

Design & Aesthetics

Visually, the FoKus Amadeus is a departure from Noble’s cool-toned aesthetics, introducing a striking red and black design reminiscent of Mozart’s flamboyant red tailcoats. The deep scarlet hue isn’t just a style statement—it’s an embodiment of the product’s expressive tuning philosophy. The faceplates are polished and tastefully branded, with a minimalist finish that still looks high-end.

In terms of ergonomics, the shape of the Amadeus is well-contoured to the inner ear, using an angled nozzle and bulbous outer shell to ensure a snug, secure seal. The result is excellent passive noise isolation, which supports the ANC functionality by blocking out a majority of ambient sound naturally. Even during extended listening sessions, the weight distribution ensures there’s no excessive pressure on the concha or ear canal.

Features & Functionality

The Noble FoKus Amadeus is packed with intuitive features that make it stand out among premium true wireless earbuds:

• Quick Pairing: Open the case and the buds instantly enter pairing mode. Manual reset or pairing can be triggered via the internal button.
• Customizable Touch Controls: Through the Noble FoKus mobile app, users can assign touch functions—play/pause, volume, ANC toggle, etc.—to each earbud independently.
• Personalized Sound by Audiodo: One of the standout features, this software creates a tailored EQ curve based on your hearing profile using a short calibration test. It’s especially useful for users with slight hearing asymmetry or frequency dips.
• EQ Tuning: Fine-tune bass, mids, and treble bands to your liking.
• ANC & Ambient Modes: Easily toggle between noise cancellation and transparency for situational awareness.
• Multi-point Bluetooth: Connect to two devices at once—a lifesaver for switching between work calls and music.
• True Wireless Mirroring: Ensures optimal stability by automatically switching to the bud with the best signal.

The Amadeus isn’t just “feature-rich”—it’s feature-smart, giving users both control and customizability, which is a rarity in true wireless IEMs.

Active Noise Cancellation (ANC)

While the Amadeus may not unseat ANC titans like Sony’s WF-1000XM5 or Bose’s QuietComfort Earbuds II, its ANC is commendably effective. It tackles low-frequency hums (train noise, HVAC systems) and consistent chatter with ease. It doesn't fully eliminate sharp, sudden sounds, but the tight passive seal works in tandem with ANC for a smoother experience.

The real trick here is in how naturally the ANC is implemented. There's no pressure buildup or artificial vacuum feeling—an issue found in many other ANC earbuds. The Transparency mode, on the other hand, feels balanced and lifelike. It doesn’t overemphasize ambient sound or create harshness, making it perfect for commuting or quick conversations.

Listening Review

Soundstage

The FoKus Amadeus offers a surprisingly expansive and immersive soundstage for a closed-back TWS. Though it won't match an open-back headphone, its ability to project depth, height, and lateral imaging is impressive. Instrument placement is coherent and layered, giving breathing room to each element in a mix. There’s a cinematic quality here that makes orchestral and live recordings especially engaging. Mozart string quartets, for instance, unfold with clarity, dynamic swells, and a sense of being in the room with the players.

Low Frequencies

The bass is tight, punchy, and well-controlled, with a slightly elevated sub-bass that adds excitement without muddying the mids. There's a satisfying weight and grip to kick drums and electronic basslines, yet the presentation remains articulate. Sub-bass notes in tracks like James Blake’s Limit to Your Love are both visceral and clean. The layering and texture of bass guitars and synths are preserved, lending warmth without smearing.

Midrange Frequencies

Vocals sit front and center in the mix, offering a clear and emotionally resonant presentation. Whether it's the intimacy of Norah Jones or the grit of Thom Yorke, the midrange has strong timbral accuracy and complex resolution. Instrument layering is superb; guitars and synths occupy distinct spaces without crowding. There’s natural decay, particularly in acoustic instruments, which helps deliver a realistic and engaging midband that’s critical for critical listening and vocal clarity.

High Frequencies

Treble is refined, sparkly, and non-fatiguing. The Amadeus doesn’t boost treble artificially to simulate “detail”—instead, it captures it organically. The top end reveals micro-details like string overtones, vocal breaths, and cymbal decay, adding to the sense of air and space. Tracks with bright or complex upper ranges never sound piercing. The tuning strikes an ideal balance between extension and smoothness, making it suitable for long sessions without ear strain.

Amadeus vs. Rex5 vs. Prestige – Which Noble TWS Is Best?

Noble Audio’s premium TWS lineup currently includes the Amadeus ($320), Rex5 ($449), and Prestige ($599). Each model has its own strengths, but how do they compare?

Amadeus vs. Rex5:

Both models feature EQ customization, ANC, and Personalized Sound via Audiodo. In terms of fit and interface, they’re quite similar. However, the Amadeus delivers a warmer and more dynamic tuning, while the Rex5 leans slightly leaner and more analytical. Given the $100 price difference, the Amadeus offers excellent value for those who want flagship features without the flagship price.

Amadeus vs. Prestige:

The Prestige prioritizes sound fidelity over features—no app-based EQ or ANC. However, its sonic performance is top-tier, with a wider soundstage and elevated precision. If you’re an analytical listener or audio purist, the Prestige might win out. That said, the Amadeus presents a more balanced and accessible profile, especially for those who want both customization and musicality in a single package.

Summary

The Noble FoKus Amadeus is an outstanding true wireless earbud that combines audiophile sound quality, advanced customization, and premium design. From the emotionally engaging tuning to the wealth of app-driven features, it presents an exceptional value at $320. For listeners who want high-end audio on the go, the Amadeus makes few compromises and many statements.
