Amazon's Echo Loop looks almost like a normal titanium ring at first glance — albeit bigger and bulkier. But when you take a look at the ring's underside, you'll notice that there's a tiny button for triggering Alexa. After you're done asking Alexa a question or issuing a request, you must hold the ring near your ear to hear its response. This is all possible thanks to the ring's tiny speaker and two microphones.
During my time using the Echo Loop, I pressed the button and spoke into the ring to set a reminder and ask for the weather. It was a bit difficult to hear Alexa's response in such a crowded room, but Amazon's digital helper seemed to respond just as quickly as it would when being used through any other Echo device. Users will be able to control the volume of its voice in the Alexa smartphone app.
Making phone calls through Amazon's smart ring is certainly possible, although I wouldn't recommend doing so for any conversation that takes longer than a few seconds. Because you have to move your hand close to your mouth to speak and then hold it near your ear to listen, I imagine making phone calls through the Loop is uncomfortable.
If you want to do so, you can designate a contact that will be called whenever you double press the action button.
You can also press and hold the button to access whichever virtual helper you normally use on your phone — Siri or the Google Assistant.
