I am adding a wireless speaker with 3.5 audio capability to this set of bookshelf speakers and I connect all three speakers to my tablet with a 3.5 extension cable to get stable sound at both ends of the room . No, it's not as easy as using Bluetooth, but the wired option WORKS. EVERYONE. TIME. No annoying noises, no abrupt entrances and exits. And my "wireless" speaker's battery lasts longer because it doesn't have to maintain a BT connection. I wish I had bought this many, many years ago.
