Best Compact Wireless System 2025 - Robb Report
The Premium Wireless Speaker Your Music Deserves
Naim Audio's Mu-so 2nd Generation is the successor to the multiple award-winning Mu-so wireless music system. The 2nd Generation model has been re-engineered for class-leading performance, functionality and usability by Naim's experts in Salisbury, England.
Combining Naim's 45 years of hi-fi mastery with the very latest music-streaming technology and premium design quality, this is the ultimate single-box system you and your music deserve. From up to 32-bit high-resolution streaming to multiroom music to HDMI TV sound, you’ve never heard an all-in-one wireless system quite like this before.
Award-Winning Performance
The Muso 2 grabbed the Best Compact Wireless System Award 2025 from the Robb Report.
”Launched in 2019, it’s still the best-looking, most user-friendly all-in-one system we have found, one that spreads a sound field whose full-range presence belies the elegant form factor that complements even the most sophisticated interior.”
”That so much powerful sound can project from such a simple-looking – and simple-to-use – component is hard to believe. The perfect complement to a hard-earned martini at 5:01 p.m., the Mu-so could become a happy habit, a sonic relaxer whose music brings tranquility to the end of a hectic day."
"Recommended Component" Honors
Stereophile honored Naim Audio's Mu-so 2nd Generation by awarding it the magazine's coveted Recommend Component status for 2024.
According to Stereophile, Reviewer JMu [Julie Mullins] was "impressed by the sound, writing 'a few sonic characteristics stood out: crisp clarity with more detail and dynamic output than I expected. Subjective impressions of bass extension seemed to exceed what's possible from small drivers within a smallish box.' How did JMu conclude her review? 'The musical Mu-so 2nd Generation offers serious sound and engineering from a respected maker, but it's also built for fun. I wanted to keep on listening, and that speaks volumes.'"
"Naim Just Crushed It"
"There's increasing competition in the 'premium wireless speaker' market, but Naim Mu-so 2 just crushed it," raves T3, May 2019. "An awesome, thumping wall of sound and reliable, versatile software platform make for the perfect 21st-century music experience."
p align= "justify">"In every meaningful respect – dynamism, low-frequency presence, high-end attack, you name it – the Mu-so 2 advances on the original Mu-so," notes trustedreviews.com, June 2019.
"It has more rivals to face than the Mu-so ever did - but those… only exist because of the new ground broken by Mu-so. And Mu-so 2 seems more than capable of maintaining its predecessor’s position at the front of the pack," reports Stuff magazine for June 2019.
The Naim Streaming Platform
At the heart of Mu-so 2nd Generation is Naim’s music-streaming platform, developed by 25 engineers over three years to offer the very best performance whether playing your own digital music collection, a world of Internet radio, or music streaming services such as TIDAL and Spotify. This acclaimed platform is unique to Naim music-streaming products and can be found in the high-end Uniti range and dedicated network players, including Naim's £20,000 flagship ND 555.
An All-New DSP is the Heart of the System
Naim's all-new multicore Digital Signal Processor (DSP) achieves the highest level of performance, providing 2000 MIPS (Million Instructions Per Second) compared to the original Mu-so’s single-core, 150MIPS DSP. Thanks to the lightning-quick processing speed, you can also hear even more from your music than before.
Naim has also created a brand new limiter algorithm that keeps each of Mu-so 2nd Generation’s speaker drivers’ movement under control even at high volume levels. The new limiter, by design, is only active at extreme volume levels and helps to retain the music’s clarity while increasing long term reliability.
Optimized Speaker Drivers
Mu-so 2nd Generation’s 450 watts of music power are joined by improved and highly optimized speaker drivers – a joint development project between Naim and Focal R&D departments. Focal has been creating benchmark acoustic equipment since 1979, and its expertise has taken speaker-driver precision and performance to new levels.
95% Re-engineered and Upgraded 2nd Gen Design
The Mu-so 2nd Generation puts across a stunning appearance in its premium aluminum casing with a new burnished grey finish. It may look similar outside to the original Mu-so, but inside Mu-so 2nd Generation, the majority of components have been upgraded to improve performance.
The cabinet design has been re-engineered to create 13% more internal volume, enabling bigger, better bass. Both the cabinet bracing and baffle molding have been redesigned for improved rigidity, which suppresses and controls vibrations.
The distinctive heat-sink fins are now more compact, while still being ultra-effective, and continuing to feature Naim patented technology that discreetly incorporates the wi-fi antenna.
Upgraded App Control
You can use your smartphone or tablet to control the Mu-so. The updated Naim app allows you to browse by artist, genre, album and more, complete with artwork and extended music information. You can also use the app to control volume, light settings, and room modes, and also to create playlists.
For those times when your phone or tablet aren't handy, an infrared wireless remote control is included, too.
Discover the New Intuitive Dial
You can also take control of the Mu-so via the sleek front panel. The new intuitive interface has 15 touch sensitive buttons and a bold, illuminated volume dial with a proximity sensor that wakes the display.
Among many other functions, the interface makes it easy to create a multiroom group with other Naim products, tap to pair Bluetooth device, cycle through external Inputs (HDMI, digital, analog), tap to play from a USB device, and tap to resume a play queue (Spotify Resume if you're logged in). You can directly access favorites. Plus. There's a Chromecast indicator and an AirPlay indicator.
Multiroom Music Made Easy with Smart Integration
Mu-so 2nd Generation works brilliantly on its own or as part of a multiroom music set-up. There are three easy ways to make it multiroom.
The first way is to combine it with other networked Naim products (including 1st Generation Mu-so and Mu-so Qb) via the updated Naim app. Second, you can pair it with other AirPlay 2-compatible wireless speakers via the Apple Home app. The third wat is to pair it with other Chromecast devices via groups controlled by the Google Home app.
