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).

Maximum volume

How we test maximum volume

We test how loud speakers will go before the sound distorts, so you know how loud it can actually go and still sound at its best, rather than the claimed maximum by the manufacturer that can stretch the speaker beyond its limits. Choose a speaker with a louder maximum volume to fill larger spaces.

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.

Energy efficiency from mains

How we test energy efficiency from mains

If a speaker can be powered off batteries, the energy efficiency rating is based on battery life from a single charge compared to the competition - in this case, it's therefore not a measure of total energy consumption, as a speaker could have a better battery life through having a larger battery. If the speaker is mains-powered only, the energy efficiency rating is based on power consumption from the mains - we test both when the speaker is playing and when it is on standby. Power consumption tends to be pretty low for speakers, but can add up particularly for mains-powered speakers you have plugged in a lot of the time.
