Sonos Roam review: A good speaker in a small package
The most compact -- and most affordable -- speaker in the Sonos lineup, the $169 Roam is easily one of the best mini wireless speakers you can buy.

Sonos calls the Roam "the best-sounding ultraportable speaker ever made." That's a big claim, so needless to say, as soon as I got my hands on a review sample, I was eager to hear whether it lived up to that lofty billing. I'm happy to report that to a large extent it does, at least compared to other speakers of similar size and weight.
Available in white or black for $169 (£159, AU$279), the Roam is currently Sonos' smallest and most affordable speaker (if you don't count those $99 Sonos-compatible Symfonisk Ikea Wi-Fi bookshelf speakers), though it's fairly expensive for a mini wireless speaker. This model, like Sonos' earlier Move portable speaker ($400, £399, AU$649), is equipped with both Bluetooth and Wi-Fi and can tap into your existing Sonos multiroom audio system and link with other Series 2-compatible Sonos speakers. (Sonos moved to its new S2 app last year, creating some havoc for owners of legacy Sonos devices that aren't compatible with the new app, bifurcating users' multiroom setups.) It also supports Apple AirPlay 2, so you can cast audio directly to it from an Apple device without using the Sonos app.
With its smooth matte finish and clean design, it's one of the classiest looking portable wireless speakers I've tested -- and smaller than I thought it would be. It weighs just less than a pound (430 grams) and it's basically about the size of a JBL Flip or UE Boom Bluetooth speaker. Sonos' Move weighs about six times as much and really isn't so easy to carry around. Compared to that, this feels downright light. It's also shock resistant -- the end caps are rubberized -- and seems pretty durable. It has an IPX67 rating, which means it can be fully submerged underwater (up to 1 meter) for 30 minutes and it actually makes for a very good shower speaker.
Wi-Fi at home, Bluetooth on the go
As noted, like the Move, this speaker also has built-in Bluetooth. But what's new is that when you're away from your home network the Roam will automatically switch over to Bluetooth and switch back when you're within range. The Move doesn't do that; you have to manually activate the Bluetooth on that speaker.
I initially linked the speaker to an iPhone 12 Pro and the transition from Wi-Fi to Bluetooth seemed to work smoothly over the three days I tested it. Where things got a little trickier is when I wanted to switch the Roam over to Bluetooth on a Google Pixel 4 XL Android smartphone when I was out and about and using the Roam as I would a typical Bluetooth speaker. The power button next to the USB-C charging port doubles as a Bluetooth button and allows you to put the speaker into Bluetooth pairing mode. But it took several button holds and releases to finally get the speaker to show up in the Pixel's menu for Bluetooth pairing.
In general, the Sonos app and software powering its system are quite user friendly. However, from my experience, you will run into some snafus from time to time, including issues with integrated voice assistants (you can choose either Amazon Alexa or Google Assistant) when you're dealing with a Wi-Fi speaker that relies on a home network as opposed to a simple Bluetooth speaker. That said, the Roam will get future software updates that should help refine its operation further.
Aside from the auto Wi-Fi to Bluetooth switching, the other cool feature this has is both USB-C and wireless charging. However, I should note that no power adapter is included, just the USB-C cable, and the speaker requires at least a 10-watt power adapter for USB-C charging.
As for wireless charging, Sonos will sell you a 10-watt wireless charging dock for $49 but you can set the speaker down on just about any Qi wireless charging pad and it will charge at up to 15 watts so long as the charging pad supports that speed. You can also charge the speaker with the included USB-C cable and that's the fastest charging method, depending on the power output of your power adapter. With a 20-watt power adapter, I charged the speaker to about 50% in an hour via USB-C. Wireless charging takes about double that time to get to 50%.
Battery life is rated at around 10 hours at moderate volume levels, but that number may drop a bit if you're on Wi-Fi rather than Bluetooth and it could be adversely impacted with voice-assistant usage. As I'm shooting this video, Sonos says it's working with Google to issue an update that improves battery life of the speaker when Google Assistant is enabled.
All of Sonos' new speakers, including the Roam, offer some form of the company's Trueplay sound-tuning feature to optimize their sonic profiles for the space in which they're placed. Rather than use the Sonos app on your iPhone, however, the Roam uses its built-in microphones to monitor its surroundings and continually autotunes itself on the fly.
When on a Wi-Fi network, those microphones are also used to access Google Assistant or Amazon Alexa with your voice -- you have to choose one voice assistant or the other -- and you can pass audio onto the closest speaker in your Sonos setup by holding down the pause/play button on the Roam. Sonos calls this new feature Sound Swap. The Roam is able to do this by listening for chirping noises played through your other speakers and determines which one is closest. I guess the idea is that you'd walk in from your patio and then fire up the speakers in your living room.
I had some fun moving the Roam from room to room, as well as outside like I would any Bluetooth speaker. And my first reaction after setting it up was, wow, this sounds really good for a speaker this size. It's not up to the same level sound-wise as the Sonos One or the Move, which produce more sound with more bass, but it's closer than I thought it would be and can fill a small to medium-sized room with sound.
Where this beats other small Bluetooth speakers like those from Ultimate Ears, JBL and others is it has more bass and sounds a little fuller with decent clarity. It's also more natural sounding. Like any small speaker, you can't push it that hard -- it has its limitations -- and it can end up sounding great with one track and only pretty good with other tracks, especially when you crank the volume. But it has a pleasant sound profile with relatively well-balanced sound that doesn't come across as overly processed (that's what I mean by more natural sounding).
You can also link the Roam with another Roam and create a stereo pair. They do sound pretty impressive paired up – getting that stereo separation gives the sound that much more depth – but you'll have to pay around $350 to create that setup. I should also add that you cannot use a pair as the rear speakers in a Sonos surround sound setup. You'll have to go with the Sonos One or those Ikea Symfonisk speakers (there's also a Symfonisk Sonos lamp speaker that works as a surround speaker).
Aside from those mini Bluetooth speakers I mentioned, I pitted the Roam against the JBL Link Portable, which seemed like the most apt comparison considering the Link Portable carries a list price of $180 and has both Wi-Fi and Bluetooth connectivity.
The Link Portable is a bigger speaker and can play both louder and has more kick to its bass. But the overall tonal balance of the Sonos was more appealing to my ears. The JBL is very good but the Sonos is smaller and better designed -- if I were given a choice between the two speakers, I'd take the Sonos.
Now, as for whether this is the best sounding ultraportable speaker ever made, I think it comes down to your definition of ultraportable. There are some speakers that are bigger, like Anker's $100 Soundcore Motion Plus, that are able to match the Sonos' sound. And there are Bluetooth speakers that cost a lot less, such as the Tribit MaxSound Plus ($50), that sound surprisingly decent and are a better value if all you're looking for is a mini portable speaker. But for its size, the Roam is pretty hard to beat, so I'm going to say Sonos' claim is within the realm of the truth. At least with what's out there right now in its size class.
While the speaker is far from cheap, it is a lot cheaper than the Move, giving Sonos another speaker in its lineup that costs less than $200. With that more affordable pricing, Sonos is hoping the Roam not only appeals to Sonos newbies on a tighter budget but to existing Sonos users looking for an ultraportable speaker that can leave the Sonos nest but be right at home when it returns home. In fact, with its attractive design and strong sound quality, if you already have a Sonos setup, it seems hard to resist, and note that if you own older Sonos equipment, you can get up to 30% off the Roam and other new Sonos speakers as part of Sonos' upgrade program.
