Shockingly poor integration with Echo devices. I really expected much more from Amazon with this product. Today, music streaming is more than just for Bluetooth Headphone connected to a smartphone. Let me outline the short falls, so others can lower their expectation. If you wish to continue listening when you get home, say on your Echo, you must select Cast in the app, on your phone, which almost works. You will not be able to control the volume from your phone, LIKE IN CAN from Spotify. Why???
