Chromecast
Google may surprise everyone with more than one Chromecast when it announces new products in late September. According to 9to5Google, Google is also working on a Chromecast that's designed for streaming music and other audio. It's apparently called Chromecast Audio, and it'll hook up to speakers through a standard 3.5mm headphone cable.

User will apparently be able to hook up multiple Chromecast Audio units to speakers throughout a home and have them play music in sync, too. The key use of this device will certainly be playing music, which makes it a big deal that Spotify is said to be among Google's partners — a key addition to Chromecast's existing support from Google Play Music, Pandora, and Rdio.

An announcement is expected September 29th. In addition to Chromecast Audio, a second-generation Chromecast is also supposed to be introduced with faster Wi-Fi, according to the report. While 9to5Google's original story mentioned the audio-only product, it was unclear at the time if it was a mode for the video Chromecast or a separate device — its new report clarifies that it'll be the latter. The bigger story, of course, will be Google's two new Nexus phones, apparently named the Nexus 5X and 6P.

The device was allegedly going by the codename “Hendrix,” which makes sense given it being audio and music-focused.

This device will, according to the documents and sources, have multi-room support, which could mean that several devices could power multiple speakers outputting the same audio at the same time. Additionally, the device is said to have the ability to mirror the audio coming from the user's Chrome browser or an Android phone. Google brags that the device will feature “high-quality” audio, and that Spotify will indeed support it.
