Does the Vizio pair with bluetooth speakers of any brand?
If it does then it should work with the Sony speakers too. TV manual should tell you how. Only 1 speaker will pair with the TV.
If it doesn't then you could get a bluetooth transmitter that can pair with 2 speakers. You won't get stereo with 2 separate speakers. You will get mono out of each. You can only get stereo out of a stereo pair or the JBL speakers that work with their Connect+ app.
