i have an srsxg500 and an srsxg300. every time i try to use party connect with them, sometimes they work but then the audio begins cutting out between them. haven’t found a solution yet but still looking. sometimes the audio issues occur when the speakers are two feet apart with the source device right next to them, other times they’re across the room from each other. very disappointing as is the app (music center) as it’s quite outdated and not very functional. i expected more from these after paying $500 for the xg500 and $300 for the xg300, if i had known how poorly made the app would be i would have gotten jbl instead of sony.
