I purchase an Element TV with Roku installed using the basic remote. Am I able to purchase the voice remote and make it compatible with Element TVs?
Yes, buy the $19.99 Voice remote, the Enhanced Voice remote only works on certain Roku tv with these model numbers:
Roku TV (model series 6000X, 7000X, C000X, 8000X, A000X)
The Enhanced Voice remote has the headphone jack, thats the feature that doesn't work on most roku tv's. The rest of the remote including the Voice search will work on all roku tvs.
