Google may have more than one Chromecast to show when it announces new products later this month. 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.

You'll 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.
