Amazon's Alexa can hit the town with you, thanks to these smart headphones

If you've become fond of Alexa, a new pair of wireless headphones lets you take Amazon's digital assistant with you on the run -- literally. "When (Apple co-founder) Steve Jobs announced the iPod, the pitch was: A thousand songs in your pocket. Now, it's 20 million songs at the sound of your voice," said 66 Audio CEO and founder Kristian Kay. "You can ask Alexa to play you any song from multiple services ... and instantly, without ever touching your phone, you have this unlimited jukebox where you now can listen to any music that you want, on demand." This is just the latest evolution of Alexa-enabled technology.
