With a built-in Alexa connectivity, the Amazon Echo Frames 2nd Gen Smart Glasses provides you assistant and convenience all day. Hands-free prompting is better than a screen display that distracts you on the lenses. Furthermore, the Open-ear audio functionality allows the sound to direct toward your ears while keeping the noise level down for those around you. The Echo Frames features 2 hours of talk time, 4 hours of media playback, and touch use adjustment to modify the volume and other functions. In total, the glasses can go up to 14 hours charge, that far powerful than the previous model. If you prefer another voice assistant, the Echo also supports Google Assistant and Siri.
