The spherical Echo might look like the Echo Dot, but it’s physically larger and has improved speakers. There’s a 3.0″ woofer, along with dual front-firing 0.8″ tweeters. Unlike any of Google’s smart speakers, the Echo has a 3.5 mm line in/out port, so you can connect different speakers or plug in a new audio source. Finally, the speaker can act as a hub for Zigbee devices, and it might have support for the new Matter standard in the future.
