Amazon took a whole damn Echo speaker and put it into a ring and called it the Echo Loop. It’s part of a program Amazon is calling “Day1,” which is code for “here are a bunch of products that are not really ready for mass sales, but we want to put them out there anyway.” The first two are the smart eyeglass frames and this little ring.
It works, but the audio is not very loud. That is probably a combination of design and necessity, as the idea here is you don’t want everybody to know what you’re doing. There is a small button on the inside, and you reach in and press it with your thumb. When you do, there’s a tiny vibration that confirms that Alexa is listening.
