Samsung 200 Watt, 4.1CH, Bluetooth Sound System

Would it work with my weeks-old Samsung 55" uhd tv?

Would it work with my 65" curved tv?

Your TV’s should work with it. As long as they have a “optical audio out” port, they should be fine.

Are the rear speakers battery-powered?

I hope to God Samsung has not produced a battery powered set of rear speakers that also require the power from using Bluetooth. Has anyone heard the wireless surround speakers to give an opinion on quality?
