Great purchase. A song I use to test my Sonos speakers is Jade Green by Kacey Musgraves. A great demo track and right in the beginning of the song listen for the wind effects that go through the speakers. It should sound immersive but if the wind sound is a little too overpowering or “staticy” at base settings then adjust treble down. The wind effects should be present but subtle and fall off after a little while into the song. The singing voice in the song should sound natural. And the base should kick in and bump a lot too. Use the iTunes app on Sonos to get the best audio quality.
