This is perfect! Although I have a Roku, there are some things that I cannot stream on Roku (like WatchTV for AT&T). I have an app on my phone that I can stream from and this was the perfect cable! It is so easy because I just connected it and it mirrored from my phone screen. I have a Samsung Galaxy S8. Super handy and perfect. The sound transmitted easily.
GREAT quality! And it's long enough for me to put on a separate table. This works well. Just what I needed if you don't want to buy additional streaming tools!
