The company known for integrated whole home speaker systems launches its smallest speaker yet... and it's a big deal.

A brilliant wireless speaker with Bluetooth, Wi-Fi, Alexa and Google Assistant support

Sounds phenomenal for the size; Alexa and Google Assistant support; Qi wireless charging;

Voice assistant setup can be a pain; No charger supplied in the box; No 3.5mm audio input;

Apart from a couple of small niggles, the Sonos Roam is a brilliant speaker combining Wi-Fi, Bluetooth and smart features into a stylish, compact and durable design.

Excellent sound; Thoughtful IP67 design; Lots of smart features; Wireless charging;

Bluetooth limited to streaming; Battery life behind rivals;

The versatile Sonos Roam can easily be moved between your home speaker setup and the great outdoors, though you're paying a premium for convenience over audio quality.

Mono output; Digital signal processing can overwhelm the audio at high volumes; Not as loud as similarly priced speakers

For those already invested in Sonos, this portable speaker is an absolute no-brainer addition to the family. For those considering a Bluetooth speaker and wondering if the Roam is worth the investment over others the answer is yes. It delivers everything a Bluetooth speaker should, yet so much more.

Lightweight and very portable; Excellent sound quality for this size; Water-resistant design; Google Assistant and Alexa; Sonos features on Wi-Fi; New Sound Swap feature;

A little pricey; Rubber ends dent; No accompanying case; Can't use two Roam devices as surrounds in existing setup; Battery life a little under claimed;

The Sonos Move ($399) is one of our favorite outdoor speakers, but at 6.6 pounds and nearly a foot tall, it isn't exactly the most portable model on the market. With the $169 Roam, Sonos ticks off many of the boxes you expect from a portable speaker, including a dust-tight, waterproof build, in a much more bag-friendly form factor, along with some extra capabilities that give it a unique edge over the competition. As a Sonos speaker, it supports multi-room Wi-Fi streaming that easily integrates with the rest of your Sonos system. In addition, it supports AirPlay 2 and Bluetooth, making it a lot more versatile than your standard Bluetooth speaker. It also features Amazon Alexa and Google Assistant voice integration, so there's lots of tech packed into this small design. The downside is that you're paying a premium for convenience as opposed to audio performance, as other manufacturers offer comparably priced speakers that sound notably better.The Most Portable Sonos Speaker Measuri...
