We specifically replaced the Roku remote with the one with the headphone jack. We needed some kind of wireless/wired headphone setup with a mid-to-low budget 4K TV for an elderly family member with kind of special needs. They have trouble hearing the TV speakers and a surround sound setup in a bedroom is...not ideal. Replacing the remote was pretty cheap and easy enough they could use it.
We've yet to figure out another (low cost) option since when you use the remote like this it drains the batteries insanely quickly. Regular wireless headphones won't work for him since the power button is...too confusing in his case. The Roku remote is the best bet, yet, unfortunately.
