SAMSUNG Q90R 7.1.4 DOLBY ATMOS eARC Samsung Soundbar

Hello. Selling SAMSUNG HARMAN KARDON HW-Q90R 7.1.4 WIRELESS 4K SOUND BAR DOLBY ATMOS. Used for approximately 5 years. I bought it online for over 5,000 when it first launched. Reason for selling: It requires a voltage converter from 220 to 110 because I purchased it from America. The remote has an issue; the button that increases volume doesn't work, but you can adjust volume using the TV remote.
