  • Sounds lacks the warmth and presence of Sonos One
  • No multi-room audio support
  • Limited range of music services and other third-party integrations

Ready for the smart speaker explosion? It’s taken a little time for specialist audio manufacturers to follow the lead of Amazon Echo and Google Home, but momentum is building with speakers flooding the market at a range of price points that pack Alexa, Siri, or the Google Assistant. What Bluetooth speakers were to 2015, smart speakers are to 2017 and beyond – and we’re just getting started.

We recently reviewed (and loved) the Sonos One, the company’s reinvention of their Play:1 speaker, combining superb sound quality and excellent Alexa integration (with Google Assistant coming next year). Not to be outdone, Ultimate Ears has just taken the wraps off two new, portable, Alexa-packing speakers, the $230 UE Blast and $300 Megablast.

Now there’s a smart speaker with a new (old) sheriff in town: Cortana. While Cortana has been around on the Microsoft platform for awhile, we haven’t heard her in a smart speaker. That’s no longer the case, thanks to Harman Kardon’s new Invoke Cortana-enabled speaker, available starting Sunday. Find out how well the speaker measured up to other smart speakers on the market in our Harman Kardon Invoke review.

While Cortana has been around for awhile, we haven’t heard her in a smart speaker.

While you can expect many more “me too” speakers to launch over the coming months, the Harman Kardon Invoke stands out for a few reasons. The $199 device is the first speaker to launch with Microsoft’s Cortana digital assistant (and possibly the only device, although HP and Intel have signed up to develop reference hardware, which may stimulate others to follow).

The partnership combines Harman Kardon’s premium audio expertise with Microsoft’s online services – notably Cortana and Skype – as well as Windows 10 PC connectivity, the Bing knowledge graph, Office 365 calendars and newly-announced smart home device integration.  A range of third-party Cortana skills extend features, but you won’t have the breadth of support you’d get from Amazon Alexa and Google Assistant. Restrictions on Cortana’s availability mean that the Invoke will only ship in the United States at launch.

With Harman Kardon (recently acquired by Samsung) also announcing the Alexa-enabled Allure speaker, the Invoke may represent somewhat of an experiment for all parties. The question is whether the Invoke delivers the combination of quality and intelligence that can compete against the tsunami of smart speakers flooding the market. If it doesn’t, given Microsoft’s reputation for canning hardware and services that don’t make the grade, the Invoke may end up as a collector’s item.

Refined hardware design with a beautiful finish

We were impressed by the design of the Harman Kardon Invoke, when announced back in May, with its sleek lines, gentle curves and chrome finish building on Amazon Echo’s cylindrical form.

Available in a choice of pearl silver or graphite, the Invoke has all the visual design cues you’d expect from a premium audio stable.

In hand, the impact is even more impressive. From the carbon-black packaging with spot-varnished branding, to the punched metal speaker surround and slow, weighty action of the volume ring, the Harmon Kardon Invoke bleeds quality. Even the branded (and somewhat large) power supply has folding pins, making it more convenient for travel.

While there are clear visual similarities with both Amazon Echo and Sonos Play:1, Harmon Kardon has just done enough to give Invoke its own identity. It’ll look fabulous in your home.

Impressive audio engine packed into a svelte chassis

Despite its sleek 4.2 by 9.5 inch-dimensions, the Invoke packs a mighty 360-degree audio engine under the hood. Two vertical passive radiators fitted to the top half of the device are joined by a lower cluster of three direct-radiating 0.5-inch tweeters. Below them, a further three direct-radiating 1.75-inch woofers drive the low-end. Total power output is rated at 40 W, with a frequency response of 60-20kHz (-6dB).

That’s one more microphone than the Sonos One, if you’re counting

At the top of the device, seven far-field microphones (that’s one more than the Sonos One, if you’re counting) are designed to pick up your voice from anywhere in the room but can be disabled via a rear button for privacy. In terms of connectivity, the Invoke supports Bluetooth 4.1 connections and dual-band Wi-Fi, but there’s no Ethernet port or 3.5mm input jack.

It’s an impressive array, especially when you consider the single tweeter and mid-woofer equipped in the Sonos One. While there’s no wired connectivity, the Invoke supports faster wireless connections as well as direct streaming over Bluetooth, which the Sonos does not support. But does this translate into a better listening experience?

Wide range of controllers, including Voice, App and PC

The Invoke supports manual control courtesy of a volume ring and capacitive touch panel at the top of the device. A short tap (less than three seconds) stops or responds to whatever is happening on the speaker, for example, stopping playback, answering an incoming call or cancelling a timer. If the speaker is idle, a quick tap provides a “fun fact” from Cortana – a small distraction if you’re bored, or hours of fun for the kids.

A long tap is used to activate Cortana (alongside the usual, “Hey Cortana” voice command) or to ignore a call. We found the manual controls to be intuitive and responsive; however, it’s more likely that you’ll use a combination of voice and the smartphone app to play music on Invoke. The speaker supports the Cortana Android and iOS apps alongside native Windows 10 and Windows Phone controls.

Simple setup via your smartphone

Power on the device and a cloudy, swirling pattern emanates from the touch panel. It’s much subtler than Echo’s bright blue LED ring or Google Home’s circle of indicators. Located on top of a reasonably tall device, it’s also less visible. We found ourselves having to stand up and head over to the speaker to check the display, which was quite inconvenient. However, displaying Cortana’s blue and white ring adds a little personality to the design.

Setup is performed using your smartphone and the Cortana app. In typical Microsoft-style, you’ll need to agree to a host of permissions during setup, configure your location and time zone, then your phone will hunt out and connect to the speaker. Provide your Wi-Fi details, and you’re all set as far as the hardware setup goes – it’s quick and painless.

Before you get going, however, you’ll be invited to connect your preferred music services and calendars. At this time, Spotify Premium, TuneIn Radio and iHeartRadio are the default options, with Office 365 and calendar connections also offered during setup.

Clear, punchy sound that beats Amazon and Google, but comes up short against Sonos.

We tested the Hardman Kardon Invoke alongside a Sonos Play:1, Amazon Echo and Google Home, playing a range of music over Bluetooth (Sonos excepted) and Wi-Fi.

Invoke’s audio is balanced and refined.

Invoke’s audio is balanced and refined. It can play loud, for sure, getting a little ragged at the top of the speaker’s range, but music certainly doesn’t distort as much as with Amazon Echo at high volume. There’s more than enough volume to fill a large space and the 360-degree driver positioning means that’s it’s the perfect speaker to place at the center of the room.

Compared to the cheaper Google Home, the difference in the Invoke’s audio quality is pronounced. Google Home sounded muffled and withdrawn, with muddy beats a world away from the Invoke’s clear highs, muscular mid-range and tight, punchy bass. The soundstage is narrower than you’d think, given the multi-directional speakers, but separation between instruments and vocals was reasonably good for a speaker at this price point.

Streaming over Bluetooth worked well, with pairing guided by Cortana when we pressed the relevant button on the rear of the device. Invoke offers the best streaming experience with Spotify, with Spotify Connect app controls working out of the box for playback. Open up the Spotify app on your phone, hit Devices Available and off you go.

Given the difference in speaker configuration to the Play:1, we were expecting the Invoke to top even the excellent sound quality of Sonos’ entry-level speaker. Certainly, the Invoke’s 360-degree sound is an advantage over the Play:1, but we actually preferred the warmer tone and greater presence of the Sonos speaker compared to the cleaner, tighter output of the Invoke. While the Play:1 is equipped with a single tweeter and woofer, compared to three of each in the Invoke, the significantly larger drivers in the Play:1 offer more depth and engagement overall.

That doesn’t make the Invoke a bad speaker, and it certainly beats both Amazon Echo and Google Home (the latter, easily) on quality. But Sonos Play:1 and its close cousin, the new Sonos One, remain the speakers to beat.

Hands-free Skype calls, calendars, alarms and smart home control

While Cortana has been around for more than three years, it’s been quickly overtaken by Amazon and Google’s aggressive push to dominate and control the smart home.  While Cortana may be available on 500 million Windows 10 PCs in 13 countries, the hearts and minds of consumers – and the support of hardware manufactures – is most firmly with competitors.

The launch of Invoke is designed to tackle that challenge, in part, but there’s a long way to go. Perhaps the jewel in the crown, at launch, is Skype integration. Invoke supports Skype-to-Skype as well as calls to landlines and mobiles through the speaker. We found that hands-free calling over Skype worked well, with Cortana able to connect to Skype callers by name and landlines or mobiles via a dictated number. Better still, Cortana can find and call numbers with relatively vague commands. Say, “Cortana, call the nearest Italian restaurant” and hey, that’s what she’ll do!

Calls to US phone numbers are free (for the first six months only, which is disappointing), while you can also call abroad using Skype credits. While Invoke is able to receive incoming Skype calls, there’s sadly no support for hands-free calling via your phone’s Bluetooth connection.

Invoke can access Office 365 and calendars alongside handy features like timers, alarms and lists, plus location and time-based reminders. One advantage of using Cortana is that events can be created on your PC, on your phone or the speaker and you’ll receive notifications across your devices.

There’s also integrated support for smart home devices, with Wink, SmartThings and Insteon hubs available at launch, plus direct connections to Nest and Philips Hue. We found Cortana did a good job of handling basic tasks like powering our Philips Hue Lights and even controlling brightness, but color changes were out of the question. Controlling our Nest Learning Thermostat was also mostly successful, but Cortana did complain that she was unable to change the temperature on a couple of occasions.

Perhaps the jewel in the crown, at launch, is Skype integration.

Throughout our time with the Harman Karman Invoke, the speaker’s integrated far-field microphones did a good job of picking up commands from around the room, even with music playing.

Of course, with Amazon Alexa and Google Assistant boasting ever-expanding libraries of third-party skills, you may find Cortana’s locker a little less well stocked. Whether that situation is likely to change, who knows, but Microsoft had trouble wooing developers with the Windows Phone, and the same may well be true with the corporation’s smart assistant.

While it fails to hit the highs of the Sonos One, a combination of good looks, great quality audio and a decent selection of well-executed features ensures the Harman Karmon Invoke is a solid smart speaker debut for Cortana.

Our Take

The Harmon Kardon Invoke isn’t the best smart speaker available today, but it’s a strong debut for Microsoft’s Cortana in a good-looking, great-sounding device. Skype, Outlook and Office 365 integration will attract Microsoft fans and smart home device control works well, but Invoke doesn’t have quite the quality or flexibility to beat Sonos One.

Is there a better alternative?

At $199, the Sonos One offers excellent sound quality, multi-room connectivity, a brilliant controller app and support for a variety of music services. With Amazon Alexa integration at launch and the promise of Google Assistant next year, it’s hard to beat.

There’s also the Siri-enabled Apple HomePod ($350), the range-topping/wallet-draining Google Home Max ($400) and enhanced Amazon Echo Plus ($150).

How long will it last?

In recent times, Microsoft has developed a poor reputation for sustaining consumer products and services that don’t turn into instant blockbusters. For every Xbox and Surface, there’s a Zune, Groove or Microsoft Band. With limited support from other hardware manufacturers and significant competition ahead, Invoke may well be the first and last Cortana-enabled smart speaker.

Should you buy it?

If you’re a Microsoft fan and you’re all in on Cortana, you’re going to love the Harman Kardon Invoke. Everyone else, check out the competition, or just pick up the Sonos One.
