I only have an AmazonBasic Soundbar which has Wireless Bluetooth which can be used to connect a smartphone, laptop, tablet with the wireless Bluetooth connection. I only got it because I wanted to buy a cheap soundbar for my TV, but I never used the Bluetooth wireless connection to connect it to a portable device like a smartphone.
I have one wireless Bluetooth speaker and a Google Home mini (although that's not wireless which is annoying). Would be great if these personal assistant devices were wireless.
