Re: ROKU Remotes have gone downhill since early 2000s
Sorry but the Roku Premiere 3920 will not work with headphone jack on the Enhanced voice remote. You can pair the wifi remote to 3920, and even program the 1 & 2 voice search keys, but it is not compatible with the headphones. THe 3921 Premiere + will work with the headphones.
As for the Roku tv, I doubt the 32" will work, if you want to know for sure go into the settings> system> about> Roku tv: what is model number on this line? Only the following roku tv models work with the Enhanced voice remote headphone jack:
Roku TV (model series 6000X, 7000X, C000X, 8000X, A000X)
Its the first number or letter that matters, the three zeroes change with where it is purchased or features.
