Echo Dots and Nest Minis are great for setting up a smart home, but are limited when it comes to audio. To use them as a multi-room audio system, you can only use a handful of compatible apps (for example, neither can play Apple Podcasts, SoundCloud, or Facebook Live) and they need internet connectivity to function, creating a privacy risk for your home. Those issues, plus the speakers’ poor sound quality, make them fine for smart home control, but Dio Node wins out for a robust and private home audio experience.
