For me, I combined the small SWA-9500S speakers with the HW-K850 bar without any problems. Everything works fine once the BT connection is established between the two. Nothing else to deal with.

I have had a lot of problems with these Samsung sound bars, I would advise you to get another brand. Normally, if you take everything from the same brand, it should be compatible together. If not, you can take a pack sold directly with all the equipment
