DT Editors' Rating

Everyone wants a shot at the champ. Ten years after Sonos pioneered the modern multi-room speaker system, speaker and electronics makers alike have lined up to get in on the action.

Denon’s shiny new Heos ecosystem is the latest to take on the challenge. Sticking to the tried-and-true Sonos formula, Denon’s curvy black components come in a Goldilocks’ Three Bears array of sizes: The big H7, the medium H5, and the baby H3. Denon promises premium sound quality – and begs a premium price — but the Heos have their work cut out for them if they want to best Sonos there.

And when it comes to multi-room speakers, sound quality is only part of the equation. Convenience and dependability are just as important, if not more so. How did Denon do? Read on to find out.

Hands on video

Out of the box

As the big boy of the brood, the H7 speaker is pretty brawny, with a teardrop shape and a mesh speaker screen. The speaker is heavy, and since it has no handle, it isn’t easily portable. As expected, the H5 is the spitting image of its elder, only scrunched together into a more concise shape, with a lot less weight to pack around. The H3 is the odd man out, shaped into a curvy tower that is highly reminiscent of Sonos’ Play:1 canister.

The H7 is the big Mack Truck of the series.

All of the speakers share a monochromatic color scheme in black or white, and offer succinct controls along their matte plastic exteriors, though the added volume controls make them less minimalist than Sonos’ single-button design. At the back of each speaker rests an input panel with an Ethernet connection, a “connect” button for wireless setup, and an Aux input, which also acts as a sort of bridge for Wi-Fi setup via smartphone.

Accessories inside each box are few, including only a power supply, a 3.5mm cable, and a small packet of quick-start instructions.

Setup

Sonos’ most beautiful and popular feature is its systems’ extremely simple setup. With the original Bridge add-on component, which directs all speakers to your Wi-Fi network, Sonos speakers setup in seconds with a simple touch of a button. Now that the $50 Bridge is no longer needed, the first speaker takes a bit longer to setup, but the rest follow the one-button launch format.

While it isn’t something you’ll have deal with often (hopefully), the Heos’ setup process makes it fell like it’s a generation behind. Users are required to plug into the Aux port, push the connect button, and complete a short series of tasks dictated by the Heos app. While connection usually took about two minutes, a few of our attempts took longer, even requiring closing the app and restarting, or simply waiting extended periods. It wasn’t terrible, but it also wasn’t Sonos-quick — and that’s where the bar is set.

Features and design

Each of the three Heos speakers pack a hefty load of internal components, as well as digital signal processing from Waves’ MaxxAudio system to help create a more powerful sound than what you’ll get from the Sonos trio — and though they certainly are powerful, that’s not always for the better.

The Heos system’s setup process makes it fell like it’s a generation behind.

As mentioned above, the speakers all share a uniquely rounded form factor (though the H3 goes its own way) as well as a conspicuously illuminated bar on the front that relates setup and playback status, as well as exhibiting mute and volume adjustment.

The H7 (22.5 x 8.5 x 13.5-inches) offers a whopping 5-pack of powered drivers, which, along with two passive radiators, bring a heap of power to the table. Active drivers include 2 tweeters, 2 midrange drivers, and a “subwoofer” (sizes not disclosed), which are powered by 5 discrete channels of Class D amplification. The crowded configuration explains the speaker’s hefty 9 pound load.

Heos App

When it comes to wireless multi-room speaker systems like this, premium sound quality is important, but it’s really all about the interface and playback features, and that means it’s all about the app. Denon borrowed heavily from Sonos here (like most multi-room systems we’ve seen).

The system offers three simple navigation windows to choose from, including Rooms, which shows you which devices are playing from which sources, Now Playing, which is essentially the same as what you’ll see in your phone’s iTunes or Google Play window, and Music, which allows for source selection as well as offering the only access to the settings icon to dig into the bones of the system. Along with some advanced features, the settings area holds the all-important bass and treble controls.

In addition to your smartphone or DLNA-equipped PC music library, current HEOS-capable sources include Spotify, Pandora, TuneIn, and Rhapsody. Good headliners, but not nearly as diverse as Sonos, which has had a decade to broker partners. Also, the Heos system offers no Airplay support, and we couldn’t find any obvious way to source files from our Mac such as the dedicated Mac apps for Bose and Sonos. There is a workaround for its lack of Mac support by using a third party DLNA server app such as Plex, but that’s an extra step we’d prefer to avoid.

We found some attractive features while auditioning the app. Grouping speakers is a breeze, done by simply dragging and dropping, or pinching a large group of speakers together. Volume control followed our phone’s hard keys, which made adjustment on the fly intuitive, and although we wished it was accessible from any window, the EQ system was responsive and easy to adjust — a must for this bassy bunch.

However, some drawbacks to the design gave us real pause. We couldn’t seem to find any easy way to fast-forward or back up in the middle of a song when played from our phone’s catalog, for instance, though it does work with services like Spotify. Also, only the H3 can be stereo paired, doing us no good with our tiered collection. And perhaps most annoying, when multiple speakers were grouped together in our initial testing, there was no obvious way to affect individual volume control, detracting from the magical feeling of wireless audio omnipotence. At Denon’s request, we recently retested the volume function while grouped, and a pop-up window offered easily accessible individual volume sliders. Whether the issue was a bug in our initial app is unclear, but Denon claims the feature has always been available.

Grouping speakers is a breezy drag-and-drop process.

All of that is easily forgivable for those seeking a Sonos alternative. But, unfortunately, the primary trouble that arose during evaluation of the Heos app was a simple lack of reliability. The app felt almost like a beta version, wrought with recurring problems including spotty playback, playlists we created that seemed to disappear (and then reappear later), and a habitual message reading “unable to play media,” which showed up more often than we could count when sourcing our iPhone 5’s music collection.

We could normally chalk up some of the app’s quirks to our congested office Wi-Fi, but many also reared their heads when we took the system home. It’s possible (likely, even) that Denon will address many of these issues in firmware updates. But as of now, the Heos app is not ready for the big leagues.

Audio performance

The word that comes most readily to mind after spending a couple of weeks with Denon’s Heos system is HEAVY. We’re not sure how things will change in the post-Apple era, but based on past experience, if Beats made a multi-room speaker system, we’re pretty sure it would sound a lot like Denon’s Heos. Though there are obvious differences as you transition throughout the family, each of the speakers offers a thick layer of bass, coupled with an upper register that lacks the presence and detail we expected from an old pro like Denon.

As one might expect from its bulk and weight, the H7 is a powerful piece of machinery — the Mac Truck of the series, if you will, barreling through our catalog like the T1000 tailing John Connor through the spillways of LA. The speaker was at its very best when we pulled up Muse’s track Madness, where the brilliantly-produced vocal lines and well-crafted synths were able to rise above the foundational fray. But elsewhere, bass was often less firm than we wanted, filling the foundation with thick molasses, while the treble occasionally cut a little too sharply overhead.

Perhaps the H7’s best quality is the depth and dimension of its sound stage. Its sheer size and multitude of drivers offer an expansive image, with an impressive level of stereo separation. We definitely enjoyed a lot of the heavier tracks we played from this big-rig speaker. Still, we found ourselves missing the richer textures of percussion and stringed instruments. Vocals also had a tendency to come through a little cloudy. While there’s a definite upside to the H7’s sound, we wished Denon would have added a “midrange” slider to the EQ to pump up the presence there and bring more detail to the table.

Conclusion

With app inconsistencies, a lack of Mac compatibility, and audio performance that fails to rise above the crowd, Denon’s Heos multi-room speaker system was at best underwhelming, and at worst, downright annoying. Even if big bass is your pleasure, the system falls short of the detail and accuracy expected at this price point, while the spotty app simply isn’t ready for primetime. If anything, Denon’s Heos system proves that, in the multi-room game, Sonos still reigns supreme.
