Naim Mu-so 1 vs. Mu-so 2: Which Wireless Speaker Reigns Supreme?
The world of premium wireless audio is a competitive landscape, and few brands have carved out as significant a niche as Naim Audio. Their Mu-so range, in particular, has garnered widespread acclaim for its blend of sophisticated design, robust build quality, and, most importantly, exceptional sound performance.
For audiophiles and design enthusiasts alike, the question often arises: which iteration reigns supreme? This article delves deep into the Naim Mu-so 1 versus the Mu-so 2, exploring the key differences, advancements, and ultimately, helping you determine which of these remarkable wireless speakers is the right fit for your listening sanctuary.
The original Mu-so, launched in 2014, was a revelation. It offered a compelling alternative to the often sterile-looking, albeit sonically capable, competitors. Naim’s signature aesthetic, characterized by its minimalist elegance and premium materials, was immediately apparent.
Its performance, too, defied expectations for a compact all-in-one system. Bass was surprisingly deep and controlled, mids were clear and articulate, and highs were detailed without being fatiguing. This initial offering set a high bar for what a wireless speaker could achieve.
Five years later, in 2019, Naim introduced the Mu-so 2nd Generation. This wasn’t just a minor facelift; it represented a significant overhaul, addressing areas for improvement and incorporating the latest in audio streaming technology. The stage was set for a fascinating comparison.
Design and Build Quality: A Tale of Refinement
Visually, the Mu-so 1 and Mu-so 2 share a strong familial resemblance. Both exude Naim’s characteristic understated luxury, featuring brushed aluminum casework, a substantial feel, and a prominent, illuminated Naim logo. The iconic rotary volume control, a tactile delight, remains a centerpiece on both models.
However, subtle but significant design tweaks distinguish the second generation. The Mu-so 2 boasts a slightly more refined finish, with a cleaner integration of its various components. The grilles, while similar in aesthetic, are also subtly updated for improved acoustic transparency.
The overall impression is one of evolution rather than revolution. Naim understood the success of the original’s design and opted for meticulous refinement rather than a radical departure. This ensures that both speakers remain objects of desire, fitting seamlessly into high-end interior designs.
Materials and Craftsmanship
Both Mu-so generations are constructed from high-quality materials. The brushed aluminum chassis provides rigidity, minimizing unwanted vibrations and contributing to the speaker’s solid, premium feel. This commitment to robust construction is a hallmark of Naim products, and it’s evident in both models.
The original Mu-so featured a glass-filled polymer front baffle, while the Mu-so 2 incorporates a more advanced composite material. This change, while perhaps not immediately obvious to the casual observer, contributes to improved acoustic performance by further reducing resonance and coloration.
The attention to detail extends to every facet of their construction. From the satisfying heft of the unit to the precise fit of every seam, both the Mu-so 1 and Mu-so 2 showcase Naim’s unwavering dedication to manufacturing excellence. It’s this meticulous craftsmanship that justifies their premium price point.
Sound Performance: The Core of the Matter
This is where the most critical distinctions lie. While the original Mu-so delivered impressive sound, the Mu-so 2 elevates the listening experience to an entirely new level.

The re-engineered drivers and advanced DSP work in concert to produce bass that is both deeper and tighter.
This enhanced bass extension allows for a more immersive listening experience, particularly with genres that rely heavily on rhythmic drive, such as electronic music, hip-hop, and rock. You’ll feel the rumble and the punch with greater authority, without sacrificing clarity in the mid-range.
The Mu-so 1, while good, could sometimes sound a little less controlled in the deepest bass frequencies when pushed hard. The Mu-so 2, however, maintains its composure, delivering a more nuanced and powerful low-frequency foundation that underpins the entire soundstage.
Mid-Range Clarity and Vocal Reproduction
Vocal intelligibility and the richness of mid-range instruments are paramount for any hi-fi system, and the Mu-so 2 excels here. The refined drivers and advanced processing contribute to a more natural and articulate mid-range. Voices sound more present and lifelike, with greater detail and nuance.
Instruments like acoustic guitars, pianos, and brass sections are rendered with a newfound clarity and texture. The Mu-so 1 was already strong in this area, but the Mu-so 2 takes it a step further, offering a more engaging and emotionally resonant presentation of the music’s core elements.
This improved mid-range performance means that complex musical passages are easier to follow, with each instrument and vocal occupying its own distinct space within the soundstage. It’s a testament to Naim’s engineering prowess that such refinement can be achieved in an all-in-one wireless speaker.
High-Frequency Detail and Treble
The Mu-so 2 also demonstrates an improvement in high-frequency reproduction. Treble is rendered with greater airiness and detail, without becoming harsh or sibilant. Cymbals shimmer with realistic decay, and delicate nuances in string instruments are more readily apparent.
The careful integration of the tweeter within the driver array ensures a smooth transition from the mid-range, contributing to a cohesive and balanced overall sound. The Mu-so 1, while competent, could occasionally exhibit a slightly more forward or less refined treble response in comparison.
This enhanced treble detail adds a layer of sophistication to the sound, making the Mu-so 2 a more revealing speaker that can uncover subtle details in well-recorded tracks. It contributes to a sense of spaciousness and realism that is truly captivating.
