Sonos is traditionally one of the biggest names in multi-room speakers, but the competition is really hotting up in the smart speakers space. Is it still on top or left trailing in the dust?

Sound quality

Overall

Speech sound quality

How we test sound quality

We rate sound quality using a professional panel of five expert listeners with a range of ages and musical tastes. They listen to nine recordings per turntable which cover a wide range of music and radio genres, giving a rating per recording and an overall verdict (not an average).

Voice assistant integration

How we test voice assistant integration

Our experts assess how well the smart speaker or smart display has integrated its voice assistant. We ask each device a series of typical questions and see how well it responds. Different devices with the same voice assistant will often get different ratings. For example, the voice assistant may be poorly integrated into the device's software, or the microphones may be too poor for the voice assistant to pick up what you're saying reliably.

Ease of use

How we test ease of use

The overall ease of use as rated by our lab professionals. Includes how easy it is to set up, the quality of the instruction manual and the labelling of sockets. Everyday use includes how easy it is to connect devices, wirelessly stream music and control playback features. Multi-room use includes how easy it is to set up and connect to a wireless multi-room speaker system. The portability rating only applies to models with a battery.

Features, audio sources and connections

How we test features, audio sources and connections

Our lab professionals assess the number of different ways you can connect an audio source both wirelessly and via a cable. Watch out for models with a lower star rating - some models can be quite restrictive, like only allow you to connect wirelessly or even only with wi-fi. Check the tech specs tab for full details.
