WiiM Sound

Hardware in Detail

The WiiM Sound, measuring 20 x 14.5 x 14.5 cm, is wrapped in a fine acoustic mesh and is an absolute pleasure to hold. Available in black or white, the speaker weighs 2.5 kilograms and brings a quietly confident upgrade to any sideboard or vintage dresser, its technical simplicity making it neither showy nor out of place.

A thoughtful detail: the connection strip for aux-in, Ethernet, and power is hidden on the underside, alongside a color-matched power cable and a mini jack to RCA cable that set the tone for the whole package.

The top panel, a piano-black, intensely reflective touch surface on the dark review unit, reveals five clearly legible control symbols for play, skip, and volume when touched. The small round 1.8-inch Hi-Res display on the front serves as the interface for more detailed touch control. With a swipe in the right direction it shows album art, artist name, or the current time, and enables full selection of sources, streaming services, EQ presets, and much more when the app isn’t to hand.

The included remote in matte aluminum is a match for the WiiM Sound’s refined appearance, sits comfortably in the hand, and alongside standard playback controls offers four user-defined favorites for instant music access without digging through menus. Press “1” and TuneIn starts immediately; press “2” and your current favorite album plays from Amazon Music in Ultra HD. A 4-inch woofer and two 3/4-inch silk dome tweeters deliver 100 watts of output, more than enough for larger rooms. Resolution support extends to 24-bit/192kHz, providing an excellent platform for the hi-res material offered by a growing number of streaming services.

Thanks to an automatic room calibration function, which WiiM calls RoomFit and which will be familiar from systems like Sonos, the speaker optimizes itself for its acoustic environment automatically.

Features, Functions, and Connectivity

The primary connection path into the WiiM Sound is Wi-Fi, though Bluetooth, analog RCA, and Ethernet are all available as alternatives. To get the most out of it, the WiiM Home app needs to be installed first. It handles the Wi-Fi setup smoothly and opens the door to Google Cast, Spotify Connect, TIDAL Connect, Qobuz Connect, and Alexa Cast.

Local libraries can be integrated via DLNA, Squeezelite is supported, and the device is Roon Ready. Built-in access to Amazon Music, Deezer, Napster, SoundCloud, and TuneIn, among others, covers most streaming needs depending on your subscriptions. The one notable gap is Apple, with no AirPlay 2 or Apple Music support. For users of those services, the only options are Bluetooth 5.3 or a wired connection.

The WiiM Sound also supports stereo pairing when a second Sound or a Sound Lite is available, and integrates seamlessly into the existing WiiM ecosystem.

The app provides comfortable source selection, allows browsing of linked streaming services, and keeps everything organized in favorites lists. Device management opens up an extensive range of options. The EQ adopts the 22 presets from the iPhone, which feels a little cheeky at first, but each preset is displayed across the 10-band EQ and can be individually adjusted, which is a smart solution. For those who want to go deeper, the parametric EQ offers full control over filter slope, frequency, gain, and Q factor. All three sources, Wi-Fi, Bluetooth, and aux-in, can be configured independently.

RoomFit generates its own room correction curve on top of all this, bass can be dynamically tuned to personal taste, and there’s an entertaining trick in the Bluetooth transmitter mode: the WiiM can output audio to another Bluetooth speaker. For a standard outdoor Bluetooth speaker that’s a modest party trick, but as a streaming bridge to a powerful party box it becomes genuinely useful.

The front display offers a wide range of visual options, including analog and digital clock faces, VU meters, album art, and various combinations thereof. The one criticism of the info screen is that while brightness can be adjusted manually or set to adapt automatically to the ambient light, it never gets truly dark short of being switched off entirely. In a bedroom setup, that can be mildly irritating.

In a multiroom setup, multiple speakers can be linked to a single volume control, allowing all of them to be adjusted proportionally together or addressed individually. Alarms can be set, standby timing configured, and the step size for the remote’s volume control adjusted. The feature set of the WiiM Sound and its app is genuinely extensive.

Sound

The WiiM Sound delivers exactly what you’d hope for from a system like this. Warm, broad, and expansive sound that is balanced, clear, and gripping at low to moderate volumes, filling rooms in a way that feels natural and unforced. The sound signature comes across as full, bass-rich, and well-balanced from a wide range of listening positions, creating an enveloping quality that is free of fatigue and rich in detail. At higher volumes the WiiM Sound continues to satisfy, spreading a composed richness into the room, with only a slight softening in the bass at louder levels. Sonic stability throughout, though.

As a pure party speaker it falls somewhat short, lacking the raw pressure and intensity of larger units, though that’s hardly a criticism worth holding against it. The technology integrates too naturally into a living environment for that to feel like a real shortcoming.

In stereo with a WiiM Sound Lite, a completely different world opens up, drawing you much deeper into the music and placing everything on a wide, expansive stage. Quite wonderful.

Verdict

WiiM pursues a straightforward concept with the Sound: pack as much modern, high-quality streaming technology as possible into a timeless housing with a touch area and mini display. Combine that with carefully chosen, well-arranged drivers and precisely tuned DSP, offer it as a solo unit or as part of a multiroom system, add a quality remote and a highly capable app, and the result is something that’s very hard to say no to. A small, refined streaming speaker with almost everything you could ask for.
