It begs the question: What is a smart ring, and why is it considered “smart?” What Is the Echo Loop? The Echo Loop is a smart ring, designed to work with Alexa, Amazon’s voice assistant, and the company’s line of smart home products. Just like a wedding band or conventional ring, the Echo Loop is meant to be worn on your finger—which hand you choose doesn’t matter. Amazon While the Loop has most of its functionality built-in, you'll need to use the Amazon Alexa app to alter settings and sync up with the ring in certain ways. This is an important distinction to make, because it means in addition to the ring, you need access to a supported mobile device or smartphone. The ring itself is made of scratch-resistant titanium and has a water-resistant design so it’s safe to wear almost all the time. You don’t have to worry about taking it off when you’re doing the dishes, or hopping in the shower. But this is more than just a piece of jewelry. The Echo Loop functions similar to any Echo or Alexa-enabled device, Amazon’s Echo smart speakers being the prime example. With the ring, you can interact with Alexa by asking questions, sending messages, calling contacts, adding items to your grocery lists, and much more. Essentially, anything you can do with another Alexa-enabled device, you can do with the Echo Loop. How Does Echo Loop Work? The Echo Loop allows you to communicate and interact with Alexa without having your smartphone or mobile device in-hand. On the back of the band is a small button, which calls upon Alexa as soon as you press it. Embedded within the ring are two microphones, a speaker, a battery, a Bluetooth 5.0 wireless antenna, and a Piezo haptic feedback module. When you press the action button on the rear of the band, it activates the microphones, which you then use to communicate with Alexa. After you issue your command, Alexa will respond, as she does via similar devices, using the built-in speaker. The haptic feedback module will let you know through a minor vibration that everything worked as intended, just like when you receive a notification on your smartphone. Alexa is, for all intents and purposes, an incredibly useful voice assistant that can record appointments, make calls, create to-do lists, perform web queries, and much more. Getting Fitted for an Echo Loop Before buying the Echo Loop, Amazon recommends ordering the free sizing kit. The kit includes a demo of the various ring sizes you can use to identify the ideal ring size for your finger: small, medium, large, or extra large. Amazon After receiving the kit, you're instructed to wear the demo ring(s) for at least a day to ensure you chose the appropriate size.

Unfortunately, the Amazon Echo Loop is available to select customers by invitation only. The Loop is considered a “Day 1 Edition” product, meaning it’s being made available early and in limited quantities to a small testing group. Those accepted into the program must contribute feedback that will eventually see the Echo Loop improved before a public release. Most likely, Amazon is choosing customers who are already heavily invested in the Echo product ecosystem—this is an Alexa-enabled device designed to work with all of Amazon’s other products, after all. Regardless, you can buy the Echo Loop through Amazon directly. If you’re not one of the lucky few to receive an invitation, you’ll have to wait until the public release.
