It’s obvious that Amazon is trying to make its Alexa personal assistant as ubiquitous as possible. At today’s marathon product introduction, the company debuted a wide variety of its Echo-branded Alexa-powered products, both for the home and for the outdoors.

But that presents the problem: with all these new and upgraded Echo devices, which should you get? What follows is a rundown of the basic specs, prices, and availability of the most interesting products introduced today. Take a look, and see if any strike your fancy.

Echo for the home

Amazon has updated a couple of its current smart Echo speakers and has introduced several new ones for use inside your home.

The Echo Studio is Amazon’s new high-end speaker. It’s been designed with a one-inch tweeter and three two-inch midrange speakers, 3D audio, and Dolby Atmos technology; it also offers a built-in smart home hub.

Amazon’s Echo Show line of smart displays may look like picture frames, but according to Amazon, they do much more. This version offers an eight-inch screen and a built-in camera, and includes integration with the Food Network so that you can use it as a way to watch and possibly build new recipes.

Echo for the road

If you want your personal assistant to be used everywhere, that can’t just include the home. These more portable devices give you access to Alexa anywhere you go.

Amazon is going straight up against Apple’s AirPods with its own set of wireless earbuds. Aggressively priced and including technology designed to reduce ambient noise, the Echo Buds also include a passthrough mode (so you can hear what’s happening on the street), two armature drivers in each earbud for quality sound, and the ability to access not only Alexa, but Siri or Google Assistant as well (depending on what your phone uses).

One of two products that can be considered more experimental than anything else, the Echo Frames will accommodate your eyeglass prescription, but are available by invitation only (you can request an invitation on the product page). Unlike the notorious Google Glass, Echo Frames are designed to look like regular glasses and do not include a camera or display; the idea is to keep Alexa at your beck and call anywhere you go.

Availability: On invitation

Price: $179.99

This smart ring is, like the Echo Frames, meant to keep Alexa with you no matter where you wander. Another invitation-only product, the Loop uses a button to give you access to your personal assistant and haptic technology to vibrate when you receive a call — and yes, you can hold the ring up to your ear to receive and answer that call.
