Whether used as a standalone hub or part of a larger system, it brings versatility and impressive performance in equal measure.
Design and Functionality
The WiiM Pro Plus features a sleek, compact design that blends easily into any home audio setup. Its modest footprint ensures it won’t dominate your entertainment space, yet it feels purposeful and well-proportioned.
Although constructed from plastic, the build quality is solid, with smooth edges and neatly finished surfaces. There’s no sense of fragility or poor assembly, and the unit feels surprisingly refined given its understated look.
Front panel controls are integrated through capacitive touch points, offering functions like volume control, play/pause, setup access, Bluetooth pairing, and preset selection. These touch-sensitive areas respond quickly and help maintain the unit’s clean appearance.
The inclusion of a small remote provides an extra layer of convenience for those who prefer physical controls. Its layout is simple and functional, and it includes a microphone button that enables voice control via Amazon Alexa.
Around the back, the device houses a practical mix of inputs and outputs, covering digital and analogue needs. With RCA line-in and line-out ports, optical and coaxial digital outputs, Ethernet, and USB-C power input, it’s easy to integrate into existing systems.
While the rear RCA ports are positioned a little close together, they accommodate standard cables without issue. For users with bulkier interconnects, WiiM includes a set of standard RCA cables to ensure compatibility right out of the box.
Wireless connectivity is robust, thanks to dual-band Wi-Fi and Bluetooth 5.1 support. The addition of Apple AirPlay 2 and Chromecast Audio broadens its compatibility, making it simple to stream from nearly any modern device or service.
The WiiM Home app, available for iOS and Android, is well-designed and user-friendly. Navigation is smooth, setup is guided and fast, and managing sources or linked rooms is intuitive even for those new to streaming systems.
Voice control support through Amazon Alexa adds a hands-free layer of convenience. Users can trigger playback, adjust volume, or skip tracks using voice commands when the remote’s mic is engaged.
Despite its lightweight design, the WiiM Pro Plus is well-balanced in terms of functionality and aesthetics. It sits unobtrusively among audio gear, offering smart features and essential physical connectivity in a form that’s both accessible and refined.
Key Features
At the heart of the WiiM Pro Plus is a highly capable digital-to-analogue converter, the AKM 4493SEQ. This component enables the unit to process high-resolution audio files with excellent precision and detail, ensuring a listening experience that exceeds expectations for a streamer in this category.
The unit supports audio files up to 24-bit/192kHz, handling a broad range of popular formats such as FLAC, WAV, MP3, AAC, and more. This compatibility makes it easy to stream content from a variety of sources without worrying about file limitations or conversion issues.
Alongside digital playback, the Pro Plus includes analogue-to-digital conversion using a Burr-Brown PCM1861 chip. This allows users to stream analogue inputs wirelessly to other devices in a multi-room setup, adding another layer of versatility to its role in a connected home.
Gapless playback is another highlight, preserving the continuity of live performances, classical works, or concept albums. Tracks transition smoothly without artificial gaps or fades, maintaining the intended flow of the music.
The unit supports a wide selection of streaming services through the WiiM Home app, including Spotify, TIDAL, Qobuz, Deezer, Amazon Music, and more. DLNA compatibility also means users can access music stored on local network drives with ease.
Multi-room functionality is a standout feature, with support for AirPlay 2, Chromecast Audio, and Amazon Echo devices. It’s also compatible with other WiiM products, making it a practical choice for those looking to expand audio throughout multiple areas of their home.
A variety of EQ options are built-in, allowing for fine-tuning based on personal taste or audio environment. From bass and treble adjustments to a 10-band graphic EQ and parametric EQ settings, listeners have full control over their sound profile.
For those looking to automate their listening habits, routine scheduling options are available within the app. These include wake-up and sleep timers that can launch playlists, stations, or podcasts automatically, creating a more personalised audio experience.

Experience Using the Product and Performance
Setting up the WiiM Pro Plus is a smooth, guided process that requires very little technical knowledge. Once powered on, it’s automatically detected by the app, which walks users through connection and configuration in just a few steps.
The device performs reliably across both Wi-Fi and Ethernet connections. There’s no noticeable delay or drop-out when switching between streaming services or network sources.
Once configured, the Pro Plus delivers an impressive sonic performance straight away. Even lower-quality files are presented with a clarity and balance that’s rare in streamers at this level.
High-resolution audio playback highlights the unit’s strengths in detail retrieval and spatial separation. With a 24-bit/96kHz FLAC file, every element of a mix is laid out precisely across a well-defined stereo image.
Midrange clarity is particularly strong, lending vocals a lifelike quality that stands out in most recordings. Subtle inflections in delivery, breath, and emotion are all captured and conveyed convincingly.
Treble is handled with finesse, staying crisp and extended without becoming sibilant or fatiguing. This helps add sparkle and energy to recordings without tipping into harshness.
Bass is clean and articulate, providing depth without overpowering other frequencies. It supports rhythm and groove effectively while maintaining excellent textural detail.
Even when dealing with older or compressed files, the Pro Plus manages to make the most of the available information. It doesn’t over-process or artificially brighten the sound, resulting in a natural listening experience.
Streaming from services like Spotify and Tidal is effortless and sounds consistently solid. The playback is stable, responsive, and free from audio glitches or buffering issues.
AirPlay 2 and Chromecast integration work seamlessly for casting from phones, tablets, or computers. The audio quality remains dependable, and the device integrates smoothly into multi-brand setups.
Bluetooth performance is more than acceptable, particularly for casual listening. It maintains a balanced tone and does a respectable job of handling dynamic shifts and complex mixes.
The device’s behaviour as a preamp is neutral and unobtrusive. When volume control is handled by the WiiM, it adds no unwanted colouration to the sound and respects the source material.
Analogue inputs are treated with care and retain their musicality when streamed to other zones. Although some resolution is inevitably lost during conversion, the overall sound remains cohesive and enjoyable.
Multi-room functionality is impressively well-executed, maintaining sync across zones even when using a mix of speakers and protocols. Control over grouping and ungrouping rooms is intuitive through the app.
Gapless playback is implemented precisely, which is vital for albums with continuous tracks. There’s no audible break or hesitation, preserving the intended flow of music.
The EQ tools offer meaningful adjustments without compromising fidelity. Changes take effect instantly, and both subtle tweaks and dramatic reshaping are possible depending on listener preference.
The unit remains cool and quiet throughout operation, even after hours of use. This contributes to a relaxed listening experience without any intrusive operational noise.
The Pro Plus continues to impress with its consistency and sound quality. Whether used casually in the background or for focused sessions, it brings a level of refinement that keeps listeners engaged.
