Noble Audio’s Best TWS? Comparing the FoKus Amadeus and Rex5

Noble Audio has continued to make waves in the audiophile TWS market with the release of two standout models: the FoKus Rex5 and the FoKus Amadeus. Both offer unique sonic signatures, advanced drivers, and Noble’s signature build quality. But while they may come from the same family, these earbuds offer two very different listening experiences. In this comparison, we’ll break down how they stack up in terms of design, features, and, most importantly, sound performance.

What You Get

Look & Feel

The FoKus Amadeus takes on a more minimalist and rugged design. With a compact resin shell and carbon fiber faceplate, it’s lightweight, durable, and low-profile. It fits snugly in the ear, making it ideal for workouts or all-day wear. In contrast, the Rex5 leans heavily into Noble’s high-end design language. With a stunning aluminum body and a more sculpted housing, it feels more premium in the hand and in the ear. While slightly bulkier, it still offers a secure fit, with a sense of craftsmanship that echoes flagship wired IEMs.

Design & Functionality

When it comes to driver configuration, the Rex5 is very advanced for a set of true wireless earbuds. The Amadeus has a single dynamic unit with a triple-layer diaphragm, while the Rex5 carries a tribrid configuration that features dynamic, planar, and balanced armature drivers. Other than that, the Rex5 and Amadeus feature a lot of the same technology, such as Audiodo sound personalization and noise-canceling. This works in favor of the Amadeus, as you won’t be missing out on much in terms of features if you don’t want to spend more on the Rex5. ANC is effective on both models, with neither making a significant statement over the other. I wouldn’t consider ANC to be the strongest asset of either model.

Bluetooth

Both the Rex5 and Amadeus come with Bluetooth 5.4 support for maximum range, stability, and fast pairing. They both offer multipoint connection, and Android users can enjoy listening to LDAC quality audio. The Rex5 and Amadeus are both winners here.

Battery Life

Despite being higher in price, the Rex5 has less charge time than the Amadeus. While both products are still strong in this area, the Amadeus has a slight edge over the Rex5 with 8 hours of charge compared to roughly 7 hours.

Soundstage

The FoKus Rex5 offers a wide and open soundstage, especially for a true wireless design. It maintains strong stereo separation and clean imaging, which makes it ideal for EDM, hip-hop, and modern pop. There’s a sense of space that makes instruments feel layered but never distant. In contrast, the FoKus Amadeus provides a more intimate soundstage with pinpoint imaging and a rich depth. This gives it an edge with acoustic, jazz, and classical genres. The tighter staging works well for vocals and string instruments, presenting a more studio-like environment.

Low End

The Rex5 is definitely the bassier of the two, with a clear V-shaped tuning. The low-end is punchy and deep without becoming boomy, making it great for bass-heavy tracks and energetic mixes. It has real sub-bass rumble and impact without overwhelming the mids. The Amadeus, on the other hand, offers a more refined and balanced bass response. It still has a satisfying thump, but it’s tighter and more controlled. This tuning favors precision over power, which may appeal more to purists or listeners who value clarity over fun-factor.

Mids

With a slightly recessed midrange, particularly in the lower mids, the Rex5 feels underpowered. Vocals and guitars still come through clearly, but may take a backseat to the bass and highs depending on the track. It’s not overly scooped, but it leans modern and energetic. The Amadeus shines here, offering a forward and lush midrange. Vocals are intimate and smooth, and there’s a natural tonal balance that suits a wide range of genres. Instrumental detail, particularly in the upper mids, is a highlight.

Highs

The Rex5 has bright and sparkling highs that add excitement and energy. There’s a slight edge to the treble that helps detail shine through, though it may verge on fatiguing for treble-sensitive listeners at higher volumes. You get a smoother and more relaxed treble presentation with the Amadeus. Detail is still excellent, but there’s less sharpness and more polish. It’s easy to listen to for long sessions and maintains a natural airiness that flatters complex mixes.

Summary

If you’re choosing between the Noble FoKus Rex5 and FoKus Amadeus, your decision should come down to your listening preferences and lifestyle. If you want a fun, energetic sound with strong bass and a secure fit for active use, choose the Rex5. It’s the better pick for workouts, casual listening, and genres like pop, hip-hop, and electronic music. Those who prefer a balanced, audiophile-grade tuning with better vocal clarity, ANC, and a more premium feel will find more to like on the Amadeus. It’s ideal for critical listening, commuting, and genres like classical, jazz, and acoustic.

Both earbuds reflect Noble Audio’s commitment to quality and innovation. Whether you prioritize bold tuning or refined detail, you’re getting a true wireless experience that outclasses most of the competition in their respective price brackets.
