Two Speakers In One
Most portable speakers are Bluetooth only, which means they are isolated devices that must be paired to a phone to play anything. The Roam also does Wi-Fi, which means that at home it behaves like any other speaker in a Sonos system.
That difference is substantial. Over Wi-Fi it can be grouped with other speakers, controlled from the app without pairing, stream directly from services without going through your phone, and continue playing when you leave the room with your phone.
Outside, it falls back to Bluetooth and behaves like a conventional portable speaker. Having both in one device is genuinely useful for anyone who wants a bathroom or garden speaker that is also part of a wider system.
Automatic Tuning
It measures the acoustics of its surroundings and adjusts its output, which matters a great deal for a speaker that is moved constantly between a bathroom, a kitchen worktop, a garden table and a shelf.
A fixed tuning optimised for a table sounds wrong in a tiled bathroom, and being corrected automatically rather than needing manual equalisation is the right approach for a speaker whose position changes daily.
It is not magic and it is a real improvement over no compensation, particularly in small hard-surfaced rooms where bass reinforcement is severe.
Small Means Limited
It is genuinely small, which is why it fits on a bathroom shelf and is easy to carry, and physics sets hard limits on what a small enclosure can do.
Bass extension is modest and maximum volume is limited compared with larger portable speakers. Outdoors in open air with ambient noise, it can be underwhelming where something larger fills the space.
For a bathroom, a kitchen, a bedside or a small garden, it is well judged. For a party or a beach, it is the wrong size of speaker and no processing compensates for enclosure volume.
Ecosystem And Its Implications
The Wi-Fi capability only means anything inside a Sonos system, and setting it up requires the app and an account.
That is a dependency worth understanding: a speaker whose main differentiator relies on a manufacturer's platform is tied to that platform continuing to work as expected, and account and app requirements have been a source of frustration across the industry.
As a pure Bluetooth speaker it functions independently, which is a reasonable fallback, and buying it only for Bluetooth use means paying for capability you will not use.
Against The Alternatives
Against a JBL Charge 5, the Sonos is smaller, quieter and integrates with a multi-room system; the JBL is louder, tougher and has far more battery.
Against a mains Sonos speaker, the Roam is portable and considerably more limited in output.
Against Bluetooth-only portables at similar money, you are paying for the Wi-Fi and system integration.
The Verdict
A genuinely clever product for anyone in a Sonos system: a speaker that is part of the house at home and a portable outside, with automatic tuning suited to being moved constantly.
It is small, so volume and bass are limited, and the feature that distinguishes it only matters inside one manufacturer's ecosystem.
Buy it if you already have Sonos speakers; buy a louder Bluetooth-only speaker if you do not, because the Wi-Fi half is most of the price.
At a glance
Pros
- Works over Wi-Fi in a multi-room system and Bluetooth outside
- Automatically tunes to its surroundings, which suits being moved daily
- Small enough for a bathroom shelf or bedside
- Can keep playing when you leave with your phone
Cons
- Limited volume and bass extension due to small enclosure
- Wi-Fi advantages only apply inside a Sonos system
- Requires an app and an account to set up
- Underwhelming outdoors in open air
Frequently asked questions
Is it worth it without other Sonos speakers?
Not really. The Wi-Fi and multi-room capability is most of what you are paying for, and as a pure Bluetooth speaker there are louder options with more battery for less money. It makes sense as an addition to a system.
Is it loud enough for outdoors?
For a small garden table, yes. In open air with ambient noise it is underwhelming, because a small enclosure cannot move much air and no processing changes that. Larger portables are the right choice for outdoor volume.
Why does automatic tuning matter?
Because a portable speaker is used in wildly different acoustics — a tiled bathroom, a kitchen worktop, a garden table. A tuning optimised for one sounds wrong in another, and correcting automatically is the right approach for something moved daily.
