As Sonos learned at great expense, users won't tolerate a bad app experience for long — no matter how good the hardware or sound. PSB has a quiet strength here, as it's part of the same family of companies that makes the BluOS controller app. The app is compatible with a number of streaming speakers from different brands, but the iQ2 benefits from what feels like near native integration. It's here in the app that you swap music sources, add any local libraries and control any playing media. It didn't take long, but long enough for me to start Googling around for a solution.
