Smart speakers are one of those categories where the big names — Amazon and Google — dominate the conversation, while some genuinely capable alternatives get overlooked. The Xiaomi Mi Smart Speaker is a good example. It's not as widely distributed in Western markets as an Echo Dot or Nest Mini, but it offers 12W audio output, DTS sound processing, dual-band WiFi, and Google Assistant built in — at a price that regularly undercuts both Amazon and Google's own hardware on AliExpress.
If you want a smart speaker that actually sounds good and fits into a Google Assistant home without paying Google Nest prices, this is worth a serious look.
Sound Quality: The Main Event
The headline spec on the Xiaomi Mi Smart Speaker is its 12W output — twice the rated wattage of the Echo Dot 5th Gen (3.5W + external bass) and more than the Google Nest Mini (which Xiaomi doesn't officially share wattage for, but it's modest). That power difference is audible.
Bass and Midrange Performance
The Mi Smart Speaker uses a 63mm full-range driver. It's a single driver design, so there's no separate tweeter, but Xiaomi has tuned the speaker to produce respectable bass extension for a device this size. At medium volume — the level you'd use for background music while cooking — the bass is warm and present without becoming muddy.
DTS (Digital Theater Systems) audio processing is included, which applies digital enhancement to widen the soundstage and enhance clarity. Whether DTS processing is a meaningful improvement depends on the source material, but on streamed music it adds a noticeable sense of width that makes the speaker sound bigger than it is.
High Volume Performance
Push it to high volume and you'll find the limits. At 80–90% volume there's some compression in the bass, and the driver can't quite fill a large open-plan room. For a bedroom, kitchen, or home office the 12W output is more than enough. For a large living room you'll want a proper Bluetooth speaker or a multi-room setup.
Compared to Echo Dot 5th Gen and Nest Mini
The Echo Dot 5th Gen improved significantly in audio quality over its predecessor, with a larger driver and a built-in accelerometer to reduce surface vibrations. It's a competitive speaker at similar prices. The Mi Smart Speaker roughly matches it at low-to-medium volume and has a slight edge in bass presence. The Echo Dot has slightly better treble clarity on voice podcasts.
The Google Nest Mini is frankly not impressive on audio. Xiaomi's speaker sounds considerably louder and fuller. The Nest Mini's advantage is seamless Google Home integration, which the Mi Smart Speaker also offers — so the Mi wins on hardware.
Google Assistant Integration
The Xiaomi Mi Smart Speaker runs Google Assistant, not a Xiaomi-proprietary assistant. This is a big deal for buyers outside China — it means you're getting a fully featured, globally supported voice assistant rather than a China-market AI that may not recognize your language or connect to your services.
Everything you'd expect from Google Assistant works: setting timers and alarms, playing music via voice, getting weather, controlling other Google Home-compatible smart home devices, making calls (with Google Duo), and answering general knowledge questions. Multi-turn conversations work reliably.
Smart Home Control
The Mi Smart Speaker integrates into Google Home, which means it can control any device that's Google-compatible — lights, thermostats, plugs, locks, and more. If you already use Google Home as your smart home hub, the Mi Smart Speaker slots in without friction. You can group it with other Google Home speakers for multi-room audio.
Xiaomi's own smart home devices (Mi Home / Aqara ecosystem) also connect via Google Home. So if you have Xiaomi smart lights or plugs, you can control them by voice through this speaker.
Music Streaming
The Mi Smart Speaker supports all the major streaming services available through Google Assistant: Spotify, YouTube Music, Google Play Music (deprecated but alternatives available), Apple Music (via iOS handoff), TuneIn radio, and more.
Spotify
Spotify works both via voice command and via Spotify Connect. You can ask Google Assistant to play a specific playlist or artist, or cast directly from the Spotify app on your phone. Casting quality is excellent — the speaker acts as a Spotify Connect endpoint without requiring the phone to stay connected.
Bluetooth Mode
In addition to WiFi streaming, the Mi Smart Speaker supports Bluetooth 5.0. You can pair a phone directly and use it as a standard Bluetooth speaker. This is useful for guests who don't use Google Assistant, or for streaming from apps that don't support Google Cast. Bluetooth range is solid — about 10 meters with the usual Bluetooth caveats around walls.
Switching between WiFi streaming and Bluetooth pairing is a bit clunky — you have to physically press a button on the device to toggle modes. There's no voice command to switch to Bluetooth mode, which is a minor frustration.
Design and Build
The Xiaomi Mi Smart Speaker has a fabric-wrapped cylindrical body with a touch-sensitive top panel. It looks similar in philosophy to the Google Nest Mini or Echo Dot — round, compact, designed to sit on a nightstand or kitchen counter without drawing attention.
At roughly 99mm in diameter and 85mm tall, it's slightly larger than an Echo Dot but smaller than a Google Nest Audio. The fabric comes in white/gray options. Build quality feels solid — the fabric is tightly wrapped, the base is rubber-padded to prevent sliding, and the overall impression is premium for the price.
On the top panel: tap to pause/play, press for mic mute, swipe or press volume buttons. It's responsive and works without looking at it after a day or two of muscle memory.
The power cable is a barrel connector (not USB-C, which is a minor annoyance for cable management) that connects to the included power brick.
Setup and WiFi
Setup via the Google Home app is the same process as any other Google speaker — download Google Home, plug in the speaker, follow the prompts. It took under 3 minutes in our experience.
The Mi Smart Speaker supports dual-band WiFi (2.4GHz and 5GHz), which is better than the Nest Mini (2.4GHz only) and matches the Echo Dot 5th Gen. In a crowded apartment building, 5GHz WiFi support means a more stable, faster connection for streaming.
Privacy Considerations
Like all smart speakers, the Mi Smart Speaker uses a wake word ("Hey Google") to listen for commands. The microphone is active and listening in the background when the device is powered on. There is a physical microphone mute button on the top of the speaker that cuts the mic hardware connection — a green/red LED indicates mic status.
Xiaomi collects some usage data through the Mi Home infrastructure, but since the voice processing runs through Google Assistant servers, the voice data goes to Google rather than Xiaomi. Whether that's more or less comforting depends on your perspective — but it's the same situation as any Google Assistant device.
What We'd Like to See Improved
The Mi Smart Speaker is a strong performer, but it's not without limitations:
- No 3.5mm audio output — you can't connect it to external speakers without Bluetooth
- Bluetooth mode switching requires physical button — no voice command
- Power connector is barrel jack, not USB-C — not a deal-breaker but feels dated
- No built-in display — for visual timers, recipes, or video, you'd need an Echo Show or Nest Hub
- Limited availability in some regions — you may need to import from AliExpress rather than buying locally
The Xiaomi Mi Smart Speaker delivers genuine 12W audio and Google Assistant in a compact, well-built package — better sound than the Echo Dot and Nest Mini at a competitive price.
Pros

- ✓Bluetooth 5.0 for direct pairing as a standard speaker
- ✓Compact design fits on a nightstand, kitchen counter, or desk without dominating the space
Cons
- ✗No 3.5mm audio out — can't wire to external speakers (Echo Dot 5th Gen has this)
- ✗Bluetooth mode requires physical button press — no voice switching
- ✗No display — if you want visual feedback, consider the Nest Hub or Echo Show 5 instead
Buy if...
- •Google Assistant users who want a better-sounding speaker than the Nest Mini without paying Nest Audio prices
- •Xiaomi smart home users who want voice control over Mi Home devices via Google Home
- •Buyers who stream Spotify or YouTube Music and want hands-free voice control
- •Anyone furnishing a bedroom, kitchen, or home office with a compact smart speaker
Skip if...
- •Amazon Alexa households — buy the Echo Dot 4th or 5th Gen instead for better ecosystem fit
- •Users who want a display for video or visual recipes — consider the Echo Show 5 or Nest Hub instead
- •Audiophiles who want genuine hi-fi sound — for serious listening, a dedicated Bluetooth speaker like the Anker Soundcore Motion+ will outperform any smart speaker
