The third-generation Echo Dot looks and sounds better than previous generations and supports Amazon's stereo-pairing feature that lets you use two Dots together to rock out in stereo sound -- or, better yet, pair them with the Echo Sub for bigger, booming bass. > Lastly, Amazon's three-pack Echo Dot deal is good for any of the three color choices: charcoal, heather gray or sandstone. You can mix and match colors and still get the three-pack deal.
