Both the Echo Dot Max and Echo Studio share a spherical design, with a control panel on the front. The Amazon Echo Dot Max and new Echo Studio each retain the sphere shape, but this time with a control panel front and centre. The Echo Dot Max is the smaller of the duo, and runs on Amazon's own AZ3 chip. The microphones have been improved too (over previous Echo Dot variants) to better pick up your voice commands. As for the Echo Studio, this is said to be the most advanced Echo to date.
