LG’s Music Flow line of wireless speakers are the first Google Cast speakers available for purchase, and I’ve had a chance to test them out for the past few weeks. The Music Flow speakers are very similar to what Sonos offers: there’s a large one (H7), a medium one (H5), a small one (H3), and a couple of soundbar options. The most interesting option of the lot is also the smallest: the diminutive, battery-powered H4 is the size of a regular Jambox, but has all of the same connectivity options, including Wi-Fi, of its larger siblings. Pricing ranges from $179 for the 30-watt H3 on up to $999 for the top of the line soundbar, making the Music Flow line just a hair less expensive than Sonos’ options.

All of the Music Flow speakers support Google Cast, Spotify Connect, and Bluetooth

All of the Music Flow speakers support Wi-Fi streaming with both Cast and Spotify Connect, which means they are compatible with most any audio app you might want to use. The speakers also support direct Bluetooth connections, so you can play any audio from any app if you’re not using a Cast compatible service or Spotify. If you have an Android phone, there’s NFC to make pairing over Bluetooth easier.

Playing music on a Music Flow speaker is very similar to using an AirPlay speaker. Once you’re on the same Wi-Fi network as the speaker, open your app, press the Cast button, and choose which speaker you want sound to come out of.

LG also has a Music Flow app for both iOS and Android that is used to set up the speakers on your wireless network, pair them in stereo or surround sound modes, and send music that’s stored on the phone or tablet to the speaker system. Chances are that if you’re interested in these speakers, you’ll use the app to get them set up on your network and then just head over to Google Play Music, Rdio, Spotify, or any other compatible app to play music on them.
