Amazon Echo Frames (3rd-gen) hands-on: Refined look, better sound, faster Alexa

Amazon's smart glasses have yet to impress us, but the company made big changes for its third-gen Echo Frames that could go along way in changing our minds. First, the company has upgraded the design, slimming down the area around your temples that houses all of the components. Amazon has also changed the look, continuing to make the glasses and sunglasses options look more like something you'd actually want to wear. What's more, it's working with the more fashion-minded Carrera Eyewear on smart glasses with a refined touch -- in addition to its own versions. First, there's the improved sound quality.
