A streaming speaker for audiophiles

Naim Audio has upped their wireless music game with the redesigned Mu-so Qb 2nd Generation. This compact, cube-shaped speaker offers intuitive wireless streaming with app-based control from your smartphone or tablet. And when connected to your network via an Ethernet cable, it can play even higher-resolution music files than the original Mu-so Qb. That includes downloads from HDtracks, TIDAL's high-res Masters tier, and other streaming services.

Redesigned speakers for optimal performance

The Mu-so Qb 2nd Generation features a pair of redesigned micro-fiber tweeters and midrange speakers. The speaker array is angled for full, spacious sound. The redesigned bass driver is reinforced by two passive radiators and optimized by DSP (digital signal processing) technology for deep, clean low-frequency output.

Each speaker is powered by its own amplifier, for minimal cross-interference and clear, accurate sound.

Compatible with Apple AirPlay 2

Built-in Apple AirPlay 2 technology lets you stream audio directly from your iPhone®, iPad®, or Mac® computer. That includes soundtracks from YouTube® videos and Netflix movies.

If you subscribe to Apple Music®, you can do even more. Use Siri on your iPhone, iPad, or Apple TV 4K to control Apple Music with voice commands. Tell Siri what selection or playlist to play — and which compatible Naim speakers or components you want it to play through.

Multi-room audio with the Naim app

Download the free Naim control app for your smartphone or tablet, and you have even more options. You can control up to five Naim components to create a multi-room audio system. Group your connected speakers so that the same song plays throughout the house, or only on certain speakers. You can have every speaker accessing a different source and playing a different song. Build playlists with the app, and browse thousands of internet radio stations.

Stream music with Chromecast built-in

The Mu-So Qb 2nd Generation also has Google Chromecast built-in. You can control it through the Google Home app downloaded to your smartphone or tablet. You can make your Naim speaker part of a wireless multi-room audio system with other Chromecast built-in speakers and components.

Play music from Spotify®, TIDAL, Pandora®, and Google Play Music. Enjoy internet radio from TuneIn and iHeartRadio. Chromecast built-in can also play music directly from the cloud, including high-resolution audio files up to 24-bit/96kHz.

Roon-compatible for serious music lovers


It also works with your TIDAL subscription. Roon lets you dive deep into your music, showing artist bios, photos, reviews, and lyrics. It can also suggest other artists and songs based on your selections, making it easy to discover new music you'll enjoy.
