If you are talking about "Bluetooth" audio, if it supports iOS/Android, then it also supports Windows Phone. They just specifically name those 2 because most people need to see it works with their system, but if it's Bluetooth, then it works with Bluetooth, which Windows Phone has as good as iOS and Android. It would also be compatible with Blackberry, just to cover additional bases.
IMPORTANT NOTE: If the audio system relies on a special "remote control" that pairs with a special app, then it may not work with WP. That would be a very rare circumstance, however.
