Best Smart Speaker Buying Guide: Welcome to What Hi-Fi?'s round-up of the best smart speakers you can buy in 2021.
Virtual voice assistant speakers from big-hitters Amazon, Apple and Google have never been so full of smarts. Whether you want to know today's news headlines, how many calories are in an avocado (around 250) or quick, failsafe scone recipes, Alexa, Siri and Google Assistant can now be found nestled inside certain speakers, waiting patiently for your next barked request.
Siri, Alexa and Google Assistant aren't just humble fonts of knowledge, either. These speakers play your chosen music over Bluetooth or wi-fi and, depending on the brand, also offer access to a number of different music streaming services, including Apple Music, Deezer and Spotify.
But what should you look for when selecting a smart speaker?
The first thing to consider is compatibility. Most smart speakers are platform agnostic, so they'll work with both Android and iOS devices, but the Apple HomePod Mini isn't much use without an Apple mobile device to set it up.
It's also worth thinking about which ecosystem you use most. If you frequently use Google's services – Calendar, Maps, Gmail – maybe a product with Google Home baked in would be best for you. Love shopping at Amazon and have a Prime account? An Amazon Echo might be right up your alley. (While these do both work with other services, they're tightly integrated with those made by their creators, making them much slicker to use.)
Finally: sound quality. This can vary quite a lot between models and manufacturers and spending more doesn't always guarantee a better listening experience. Some of the smaller smart speakers are limited purely because of their dimensions. Be realistic about your budget and what to expect. Luckily, every product here comes with our full fat, unabridged, comprehensively star-rated review attached – and if it didn't get at least a highly-commended four-star review under test conditions, you won't find it on this list.
From cheap budget options to premium sonic experiences, read on for our pick of the best smart speakers for music and voice features. And let's not forget, Amazon's most expensive smart device to date, the 3rd-gen Echo Show 10 just launched (on 25th February), so this page may or may not have a fresh contender in the top spot soon. Watch this space...
The HomePod Mini really is bijou. At just 8.4cm tall and 9.8cm wide, it’s quite a bit smaller than the similarly spherical new Amazon Echo. In fact, it’s even dwarfed by the new Echo Dot. Get its swirling orb of coloured light up and running (when Siri is listening or processing) though, and you realise you've got a classy performer on your hands.
Siri is your voice assistant here, and after a short period of learning it'll respond to the phrase “Hey Siri, play something I'll like” not by streaming your most played track of the last few weeks, but by playing something that you may have never listened to before but is a good fit for what you often do listen to. It’s a really powerful way to discover new music, and Alexa is nowhere near as good at it.
It goes loud, too. From the moment we start playing music, it’s clear that the HomePod Mini comfortably outperforms its size and price, quite frankly embarrassing its direct competition with the sophistication and maturity of its sound.

The question of which voice assistant to introduce to your home is largely a personal one. But by updating its most popular and affordable Echo device with this degree of skill, Amazon has laid down the most compelling case yet for choosing Alexa. Regardless of the Marmite aesthetic (yes, it looks like a little Magic 8-Ball) Alexa's responses are slightly quicker, the answers are much (much) clearer, and the sonic performance is better than ever.
Amazon’s entry-level smart device has come a long way in terms of sound quality since the arrival of the first and second Dots – so much so, you could say Amazon has come a 'full circle’ in the smart speaker arena.

The JBL Link Portable's neat connectivity features bring a plethora of streaming options to the table – features rarely seen in the sub-£150 speaker category including AirPlay 2, Chromecast and hi-res support. You also get hands-free Google Assistant, a charger cradle and wireless streaming via wi-fi or Bluetooth.
The Link Portable looks and feels like a premium product. For a speaker of this size, it has oodles of detail and an expansive mix with everything present, including bass. While there's no PartyBoost or Connect+ support for daisy-chaining other JBL speakers, the Link Portable makes JBL a serious contender in the category of affordable wireless speakers.

Amazon's inaugural smart speaker is back with a whole new look, a built-in Zigbee smart hub, and more potential under its new 100 per cent recycled hood. You don’t need an especially keen eye to realise that Amazon has started from scratch for this fourth-generation Echo.
The cylinder design has gone, in favour of a Magic 8-Ball-esque sphere, and perhaps fittingly you can ask it any question you want – as long as it’s plugged in to power and linked to your wi-fi. There's an impressive selection of third-party support, (once you’ve linked your streaming service accounts, it'll play music from Apple Music, Spotify or Deezer over wi-fi, and even if you don’t link any music-provider subscriptions, the Echo will play from Amazon Music by default – and you’ve always got TuneIn radio) and the pulsating ring of light is relocated to the lopped-off base.
Alexa feels present and useful but not imposing, the Alexa app support makes placement and multi-room configurations a breeze, and the sound quality, while a step down from superb, easily passes the sound-per-pound value test for a smart home hub of this modest price.

Bang & Olufsen isn’t noted for following the herd. In the Danish electronics specialist’s catalogue you'll find a wheel-shaped wireless speaker, a TV that opens up like a butterfly, and an 8200-watt monolithic speaker comprising 18 drivers. Its output could reasonably be described as "premium" and "innovative" – and the B&O Beosound A1 (2nd Gen) wireless speaker is no exception.
It boasts similar dimensions to a large floury bap, but that's where any comparisons with baked goods end. The new A1 supports Qualcomm’s latest aptX Adaptive Bluetooth 5.1 codec, and of course, Alexa is built-in (in a manner of speaking – it's a Bluetooth-only speaker).
It works a treat, too, delivering a pleasingly comfortable yet authoritative performance that you'd be happy listening to all day. Throw in its classy, well made design, easy to use operation and the bonus of Alexa (as long as your smartphone is nearby and connected to wi-fi), and you're looking at a Bluetooth speaker sequel that has very much been worth the wait.

The headline here is that the Echo Dot with Clock is actually the best-sounding Dot that Amazon has produced. The differences between it and the third-gen Echo Dot (listed below) aren’t huge, certainly not proportionate to those between previous generations, but they’re noticeable.
There’s no denying the Echo Dot with Clock is more comfortable keeping a tempo as well as offering more rhythmic drive than previous iterations. It’s almost as if that digital timepiece has had a beneficial effect on the music. Oh, and what if you already have a clock in the room where you want your Echo Dot? Then change the LED display to show the outside temperature or use it as a kitchen timer.

Considerably larger than any previous Echo, the Studio manages to dwarf both the Sonos One and Apple Home Pod (listed below). As well as boasting 330W of power and upgraded internals fit for CD-quality and hi-res audio (which are both now available from Amazon's latest incarnation of its streaming service, Amazon Music HD) the Echo Studio also promises to deliver 3D audio via tracks encoded in Sony's 360 Reality Audio and Dolby Atmos.
Producing immersive, directional audio is always going to be difficult, but doing it from a single speaker source is even more challenging. Nevertheless, it’s an open, airy presentation that suits the 3D environment well. The speaker sits you in the jaws of a tall soundstage, where there's a good amount of detail to percussion and high frequencies. While we're not entirely convinced by the way it handles bass – and we wouldn't exactly call it audiophile quality – for the money, the Echo Studio has a lot going for it.

If you want to get fully ensconced with the world of the digital assistant – and by that we mean with both audio and video – this is as a good a starting point as we’ve come across.
You see, where most Alexa-enabled kit on the market is audio based, concentrated on the Bluetooth speaker market in particular, the Echo Show 5 embraces both sound and video in its abilities to communicate. So, as well as playing music or reading out information, you can access video content on the Echo Show 5's 5.5in LCD touchscreen.
There’s also an HD camera, allowing the user to make Skype calls (for example), or view images from cameras in other rooms of the house – and elsewhere.
Although it can be beaten for sound quality, this is an £80 box of tricks that opens up the world of the digital assistant to a whole new audience for both audio and video; and if that’s what you’re after, this is about as good as you’ll get – especially for this kind of money.

Perhaps the smartest way to bring Amazon's Alexa voice assistant into your home, the latest generation of the Dot also doubles as a simple (and cheap) wireless speaker. The fabric-covered, puck-shaped device looks smarter then previous versions and it's easy to get up and running, either over wi-fi or Bluetooth. And as a device for playing background music, there really is little to fault, especially at this price.

Arguably the best all-round smart speaker you can currently buy, the Sonos One sounds superb for the money and has all the functionality you're likely to need. There's Spotify and Tidal integration, the ability to chat with Alexa and Google Assistant, and the option to build a multi-room system around it using other Sonos speakers or AirPlay 2. This is now the best Google speaker on the market.

The Megablast is Ultimate Ears’ loudest and smartest speaker yet. With Amazon’s Alexa voice assistant built in, it can answer your questions as well as play all your favourite tunes.
More crucially, the Megablast joins the brand’s portfolio of five-star Bluetooth speakers that are simply fun to use and listen to. Good-looking and great-sounding, the Megablast is an absolute treat.

The Audio Pro Addon C5A is almost identical to the Addon C5, which was our wireless speaker Product of the Year in 2017. So adding Alexa voice control to an Award-winning speaker is, frankly, the icing on the cake.
Available for the price of an Addon C5 plus the cost of an Amazon Echo product bolt-on, it brings the whole package into one tidy, easy-to-set-up box. And with that same Award-winning sound, this is the ideal combination for those who want an excellent Alexa wireless speaker that can be expanded into a full-blown multiroom system.

The LG WK7 is LG’s first foray into the smart speaker market and the first product to emerge as part of the new partnership with British audio specialist Meridian. There's nothing special about the design but it looks smart enough and the top features touch-sensitive controls for volume and playback. There's a Google Assistant button, too, and a function button that allows you to switch between wi-fi and Bluetooth.
There are no other connections – no analogue input or 3.5mm connection – but a smart speaker such as this doesn't really need one, especially when there's also Chromecast built-in and Android Things support.
And it sounds pretty good by smart speaker standards, not least thanks to the support for hi-res audio. A little too much bass is apparent at times and music doesn't sound quite as, well, musical, as on the HomePod, but there's impressive scale, clean and clear vocals, and plenty of punch to drums and bass. The LG WK7 is one of the best Google speakers, especially now it has a healthy discount.

It looks like your average smart speaker, but the Citation 100 produces bass by the bucket-load and can play extremely loud without strain. It is great for parties, though perhaps not so much for purists.
This Harman Kardon speaker has a pretty standard, minimalist design, and it keeps connections to a minimum, too, with no aux input. Control comes via the Google Home app and Google Assistant, and commands work well enough, though it seems slightly more prone to wi-fi drop-outs than rivals.
Sonically, while the Harman Kardon Citation 100 isn't exactly balanced, it is otherwise a tasteful-sounding smart speaker with enough scale to fill most rooms. If you don't mind that bassy over-exuberance, there's a lot to like.
