A:AnswerHello Slg, The Harmony 665 should work with your Samsung Q6 and Sony Sound Bar. Here's a link to the Compatibility Check for you to make sure: https://support.myharmony.com/en-us/compatibility. - Richard from Logitech
A:AnswerYes, the 650 uses the same program as the 700. You can add the 650 as a new remote to the Harmony program and copy all setup functions from the 700.
