Video has no captions. Useless, as I am sufficiently deaf that video soundtracks just don’t cut it. Either do captions, or post a transcript for us “unhearing” folks.
Have you looked at the Zvox sound bar available on Amazon. Uses hearing aid technology to filter out background noise. I have on on my TV which is the same as my Computer, seems to help. Other wise I use captions and ear buds which also work. Have to have a little pre-amp to use ear buds but works fine for those tough times. I found a refurb of the small unit got it pretty cheap from one of Amazons other deals. Zvox 200 here.
