First it works well with an external DAC and the first time you connect via USB, everything is set. But since Apple no longer cares about iOS compatibility with third party apps and devices, I have not been able to use it at all with my iPhone for a few months. but it works quite well with my Amazon desktop app. And since the node is Bluetooth discoverable, you can make your loudspeaker system, the sound system for your laptop. But one complaint, even hooked up to an extender over Ethernet, I lose network connectivity regularly and every time that happens, I need to reset the node.
