The C10 is by far the best sounding with the most powerful bass. It can handle very large rooms and sound great, whereas the C5A may fail to fill the space. The C3 is best used as a combination of semi-portable (due to it having a built-in battery or for smaller rooms like bathrooms and studies. Much like your Gran, however, the Swedish manufacturer could tell you how it’s managed just fine all these years without it. Sound quality is subjective. Ask even two audiophiles to compare the same speaker, and they will probably have very different opinions. At their price point, both of these multiroom speakers massively outperform the competition. If we had to choose between them, though, we would have to give the edge to the Addon C5A. For one thing, it's much more comfortable producing truly room-filling sound. With twin 3/4" tweeters and a 4" long-throw tweeter, all powered by a 40W Class D digital amplifier, it produces truly hi-fi quality sound. The Sonos One is slightly less expressive, whereas the speaker tech and layout of the Addon C5A means music of all genres has enough space to really shine. Features

This range of speakers has always been blessed with straightforward musicality, but as part of a multi-room system the range of tasks the Addon C5 is asked to perform is likely to be wider. Talk radio and podcasts are on the menu, perhaps even services as an upgrade to TV speakers. The Addon C5A has impressed me for a couple of years. I love the speaker's look and think it’s one of the best looking on the market. The multi-room wireless audio works great, but Audio Pro does need to improve its app to keep it up to date with Sonos etc.In front of the handle is the control panel. The panel is well laid out and provides users with additional functionality beyond the App that we will discuss in the next section. Centrally located, you find the volume up and down toggle switch to the left power, source, play/pause, and pairing. On the right are buttons numbered 1-4, which can be used for presets.

The C5A is designed for a normal-sized living room or bedroom. Pumping out volume loud enough to fill that area without having to push volumes above 80%, where distortion will start to occur. The Addon C5 is as happy expressing the irreverence in Mortimer’s tone – and the desperation in Dawson’s as he attempts to say something funny – as it is laying down the grooves on Echoes. You will need the Audio Pro Control App to have full functionality, linking your speakers, controlling where music is playing, and connecting them to a wireless streaming service.

Attractive design with clean lines and Scandinavian inspiration means they will suit many modern homes. Audio Pro C5-A, more lengthily titled ‘Audio Pro AddOn C5-A Wireless Voice-Controlled Speaker’, is a versatile take on the original Addon C5 model, with an increasingly wider universe of connectivity and convenience – combining modern ‘Alexa’ virtual assistant technology with an already-high spec domestic speaker for the trendy home user. The styling is reminiscent of old transistor radios but manages to blend modern and retro design aspects using high-quality materials. The cabinets are made from a high, relatively dense wood, which accounts for the weight, and they all have an aesthetically pleasing driver configuration on the front to bring cohesion to the speaker line that also includes a smaller battery-powered C3 and larger, more powerful C10. Have a speaker in every room and play to one or all at the same time, listen where you want and how you want. Enjoy high quality streaming or play music from your computer: the choice is yours. In terms of features, both the Sonos One and the Audio Pro Addon C5A are fairly evenly matched. They both come with built-in voice controls via Alexa (the Sonos One also supports Google Assistant too), which definitely makes them a lot easier to use. Simply ask the speaker to start playing something, whether that's a song, playlist, or even an internet radio station, and it will- simple!
