Bluesound Bluetooth speaker out of phase

Hi there , first post.
Often my bluetooth speakers work well , but are slightly out of time phase , which makes for some irritating unwanted remixes, can you help

thanks andrew

IMHO Bluetooth is a woefully poor transmission method for synchronised playback to different speakers YMMV

Have you synced them in BluOS or Roon?

sorry I’m a bit new to this how do you sync in roon , still having different players at different stages of the song ?

You need to group endpoints…but you can only group similar types like Apple with Apple or raat with raat
