Design Meets Utility: An In-Depth Look at the New CMF Speaker S
The portable Bluetooth speaker market has become a saturated landscape, often characterized by uninspired, pill-shaped plastic cylinders that prioritize utility over aesthetic identity. However, CMF—the sub-brand of Nothing—has consistently disrupted this monotony by injecting industrial design flair into accessible consumer electronics. Their latest offering, the CMF Speaker S, is a testament to this philosophy. Retailing at just €69, it attempts to bridge the gap between affordable audio gear and high-end industrial design.
Beyond its striking visual appeal, the device presents a unique case study in how hardware manufacturers are attempting to make tactile interaction "fun" again. In this report, we examine the specifications, design language, acoustic performance, and the broader implications of the Speaker S in the current audio market.
Main Facts: The Anatomy of the CMF Speaker S
At its core, the CMF Speaker S is a compact, 10W portable Bluetooth speaker designed for those who value form as much as function. Despite its diminutive footprint, it packs a 45mm driver capable of a frequency response range of 70Hz to 20kHz. To combat the common lack of low-end frequencies in small-scale audio, the device utilizes two passive radiators located on its sides, intended to simulate bass depth.

The device is built for durability, boasting an IP68 rating, which signifies full protection against dust ingress and the ability to withstand submersion in water. This makes it a viable candidate for beach trips, poolside relaxation, or outdoor adventures where moisture is a concern. The device is currently available for purchase across Europe, the Asia-Pacific region, the Middle East, and North America.
Chronology: From Concept to Consumer Hands
The development of the CMF Speaker S follows the brand’s established trajectory of creating "human-centric" technology. Following the successful reception of the CMF Headphone Pro, which introduced users to the company’s unique approach to rotary control, the CMF design team sought to bring similar tactile satisfaction to the portable audio sector.
- Design Conception: The engineering team drew inspiration from the humble, iconic silhouette of a milk carton. This choice was intended to move away from the "tech-heavy" look of competitors and toward a more familiar, everyday object aesthetic.
- Market Differentiation: CMF identified that the €60–€120 price bracket was stagnant. By launching both the Speaker S (€69) and its larger sibling, the Speaker M (€114), they provided a tiered choice for consumers.
- The Launch: Following a brief teaser period, the product was introduced to global markets, supported by social media campaigns (including a viral look via the GSMArena TikTok channel) that highlighted the product’s modularity and color options.
Supporting Data and Technical Specifications
To understand the CMF Speaker S, one must look at the technical trade-offs required to keep the price point competitive while maintaining build quality.

Audio Performance Analysis
The sound signature of the Speaker S is decidedly midrange-focused. In testing, the unit demonstrates exceptional clarity in vocal reproduction and acoustic instrumentation. However, the laws of physics remain an obstacle for compact audio:
- The Bass Dilemma: While the dual passive radiators attempt to provide a "thumping" experience, the low end remains subtle. It is sufficient for casual listening, but bass-heavy genres may feel slightly thin.
- The "Ultra Bass" Mode: CMF has included an software-based "Ultra Bass" toggle. Our testing suggests that while this mode does boost the low end, it often comes at the expense of overall sound transparency, causing minor distortion in the mids.
- Volume Output: With 10W of power, the speaker punches well above its weight class, filling small to medium-sized rooms with ease without significant clipping at higher volumes.
The Modular Aesthetic
The standout feature is the modularity. The speaker comes in four distinct colors: White, Red, Black, and Cyan. Each unit features a custom rotating knob that acts as the primary control interface:
- White and Red: Feature a functional lever-style rotary knob.
- Red and Cyan: Feature X-shaped or ring-shaped designs, respectively.
Users can unclip the rear locking mechanism to swap the front panels or knobs between different units. While this requires the ownership of multiple units, it signals a move toward user-customizable hardware, a rare feature in modern mass-market electronics.

Official Design Philosophy: A Tactile Experience
In statements regarding their design language, CMF representatives have emphasized the importance of "interaction." In an era where touchscreens dominate our lives, the physical act of rotating a knob provides a sense of agency that a glass screen cannot replicate.
The knob on the Speaker S is a "smart" interface. It is not merely a volume dial; it is a multi-modal controller. A simple rotation handles volume, a single press toggles playback, and a secondary press enables track navigation. This "three-in-one" approach is a clever engineering solution to the clutter of physical buttons, maintaining the clean, minimalist lines of the speaker’s exterior.
Implications: The Future of Affordable Audio
The release of the CMF Speaker S has several implications for the future of the consumer audio market.

1. The Rise of "Design-First" Budget Hardware
For years, the "budget" label in electronics was synonymous with poor design. CMF is proving that by focusing on high-quality materials and distinct silhouettes, manufacturers can command brand loyalty even at lower price points. The Speaker S feels like a premium lifestyle accessory rather than a disposable piece of plastic.
2. Modularity as a Sustainability Feature
While the modularity of the Speaker S is currently limited to aesthetic swaps, it hints at a potential future where parts (like batteries or drivers) could be easily replaced by the end user. If CMF continues to lean into this, they could position themselves as a leader in the "right to repair" movement, distinguishing themselves from competitors who glue their devices shut.
3. The "Milk Carton" Aesthetic Influence
We are likely to see a trend in the coming year of manufacturers abandoning the "stealthy black cylinder" aesthetic. The success of the Speaker S will likely encourage other brands to experiment with shapes, colors, and textures that integrate better with modern home interior design.

4. The Limitations of the Compact Form Factor
The Speaker S serves as a reminder that no matter how good the design, there are physical limitations to sound. For the audiophile, this product will not replace a dedicated home theater or a high-end bookshelf system. However, for the average consumer, it succeeds by providing "good enough" sound in a package that is undeniably superior in form and function to the competition.
Final Verdict: Is It Worth the Investment?
The CMF Speaker S is a triumph of industrial design. At €69, it is an accessible entry point for those who want a device that serves as a conversation piece as much as a source of music. While it lacks the deep, thumping bass of larger, more expensive units, its clarity, portability, and unique user interface make it one of the most compelling options in the current portable speaker market.
For those who prioritize aesthetics, tactile interaction, and portability, the CMF Speaker S is a must-have. It represents a refreshing departure from the status quo and proves that budget-friendly technology does not have to be boring. As CMF continues to iterate on this design, the potential for future, more advanced versions remains an exciting prospect for the audio industry.

Whether you are looking for a desk companion or a travel-friendly audio solution, the CMF Speaker S provides a blend of style and substance that is hard to ignore. It is a bold, fun, and highly functional device that effectively sets a new standard for what we should expect from portable audio at a sub-€100 price point.
