From the Google blog:
Today we’re introducing two new Chromecast devices. The new Chromecast has a fresh design, and is easier to plug into TVs with crowded ports. It supports the latest Wi-Fi standards and adapts more easily to changing Wi-Fi conditions in your home, so you get higher quality video with less buffering. Most importantly, we added two new colors. 😉
Chromecast Audio is a small device that plugs into your existing speakers, so you can stream your favorite music, radio and podcasts over Wi-Fi, similar to Chromecast. It works with tons of apps, including Spotify, Pandora and Google Play Music. Just like Chromecast, it works from anywhere in your home with your favorite devices, including Android, iOS, and laptops. And it’s available on the Google Store and other online retailers for just $35—way less than most Wi-Fi speakers today.
We’ve also updated the Chromecast app to make it easier for you to find great things to watch or to play, across the thousands of apps that work with Chromecast—whether you feel like browsing or want to search for a specific TV show or movie. For Cast-enabled apps that aren’t already on your phone, we’ll suggest one for you. The updated Chromecast app is rolling out on Android and iOS over the next few weeks.
Cast your media to the biggest screen or loudest speaker for a better experience.
