Harman Kardon SoundSticks 5 Wi-Fi Review: A Design Icon That Finally Streams Properly

At roughly EUR380, the SoundSticks 5 Wi-Fi sits above the standard Bluetooth version and clearly aims at buyers who care about streaming quality as much as they care about appearance. That matters, because the SoundSticks line has always sold on design first. This model tries to prove that the famous transparent look can also anchor a serious modern home-audio setup.

The price difference over the non-Wi-Fi version is not just about another wireless checkbox. Harman Kardon is effectively repositioning the system as a connected lifestyle hi-fi product rather than a design-led multimedia speaker set. In that context, the Wi-Fi edition has to justify both its extra cost and the loss of HDMI ARC on the standard model.

The SoundSticks design remains instantly recognisable, and that is still a major advantage. The clear dome-shaped subwoofer, the tall translucent satellites and the visible acoustic hardware inside the casing give the system a sculptural quality that almost no mainstream rival can match. Even more than two decades after the original concept, the look still feels distinctive rather than nostalgic.

This Wi-Fi version refines the idea without changing its core identity. The transparent plastic looks high quality, the metallic accents add a proper premium touch and the illuminated subwoofer creates a stronger sense of occasion than most living-room speakers ever manage. It is the opposite of discreet, but that is the point.

The physical proportions also help it look purposeful rather than ornamental. Each satellite stacks three 40mm midrange drivers and a 25mm silk-dome tweeter, while the central subwoofer houses a down-firing 133mm woofer. That visible architecture reinforces the feeling that this is not just a decorative object pretending to be audio equipment.

Harman Kardon has simplified the physical connection layout compared with the Bluetooth-and-HDMI version. Around the rear of the subwoofer, there is a 3.5mm input, a USB-C service port, power and the proprietary connections for the two satellite speakers. Setup is straightforward through the Harman Kardon One app, which handles Wi-Fi onboarding cleanly and supports both 2.4GHz and 5GHz networks.

The satellites still connect to the subwoofer by cable, which guarantees stable synchronisation and zero wireless lag between the channels. That is technically sensible, but it does limit placement freedom and makes cable management more important than the minimalist look initially suggests.

Touch controls on the right satellite handle volume, Bluetooth and ambient lighting, though remote control really depends on using a phone. The app is therefore a meaningful part of the experience, not just a setup utility, because it also exposes EQ controls, grouping options and lighting presets.

Connectivity is where the Wi-Fi model really separates itself from the standard SoundSticks 5. Bluetooth 6.0 with multipoint is available for easy casual playback, but the real upgrade is the network layer. AirPlay 2, Google Cast, Spotify Connect, Tidal Connect and Roon Ready support means the system slots into almost any serious streaming setup.

That has real practical benefits. Wi-Fi streaming preserves phone battery life because the speaker can pull the stream directly from the service, and it also avoids the quality limits that come with Bluetooth. Harman Kardon positions the system for high-resolution streaming up to 24-bit/192kHz in supported scenarios, which makes the SoundSticks 5 Wi-Fi much more than a pretty desktop speaker set.

Roon Ready certification in particular gives the system extra credibility for more demanding listeners, while the Harman Kardon One app can manage multi-speaker grouping and EQ without turning the product into a confusing software project. Auracast-style multiroom support is present too, but it is not yet as polished or expansive as the best Sonos or Bose ecosystems. That feature feels more promising than essential at this stage.

The SoundSticks 5 Wi-Fi justifies its existence most convincingly once music starts playing. The three-way architecture works in its favour immediately. Treble arrives through 25mm silk-dome tweeters that sound detailed and open without becoming sharp, while the six 40mm midrange drivers spread across the two satellites give vocals and instruments impressive presence and intelligibility.

This is not a system that chases detail by sounding clinical. There is warmth and texture here, especially with acoustic instruments and well-recorded voices. The separation between registers is tidy, and the speaker avoids the muddled centre image that often weakens smaller lifestyle audio systems.

It also has enough power to fill a living room properly. Harman Kardon rates the package at 190W RMS, and that headroom is evident when the volume rises. The SoundSticks 5 Wi-Fi sounds energetic and full-bodied rather than strained, provided the room and placement are sensible.

The down-firing 133mm subwoofer provides the physical low-end weight that gives the SoundSticks system its scale. It reaches low enough to handle electronic basslines and film soundtracks convincingly, but the more important point is control. Bass is strong without immediately turning boomy or disconnected from the rest of the system.

Placement still matters. Because the woofer fires downward, resonant wooden or tiled floors can exaggerate the low end if the subwoofer is placed carelessly. Once positioned sensibly, though, the bass integrates well and gives the 2.1 layout a satisfying sense of fullness.

That careful bass tuning is one of the reasons the system feels more expensive than many multimedia 2.1 sets. It does not simply add thump. It adds scale, body and drama while staying composed enough for long listening sessions.

The SoundSticks 5 Wi-Fi is not trying to be everything. There is no built-in voice assistant, which will surprise some buyers at this price. The reliance on wired links between the satellites and the subwoofer also means the setup is less visually effortless than a glance from across the room suggests.

More importantly, the Wi-Fi model drops HDMI ARC, so it is less convenient than the standard SoundSticks 5 if TV integration is the top priority. It can still work in a mixed living-room setup, but it is clearly optimised for music streaming first.

The Harman Kardon SoundSticks 5 Wi-Fi succeeds because it does more than trade on a famous silhouette. It turns a classic design statement into a genuinely modern streaming speaker system with broad platform support, refined three-way sound and enough low-end substance to feel like a proper living-room audio setup rather than a lifestyle toy.

It is not the neatest or most flexible system on the market. The lack of a voice assistant, the wired satellite connection and the missing HDMI ARC input all narrow the use case slightly. But if design, high-quality streaming and a system that actually sounds as premium as it looks matter most, the SoundSticks 5 Wi-Fi is easy to understand and easy to recommend.
