I recently saw this one on a YouTube video a guy was using. It was crystal clear on the video, so I imagine it looks good in person. I’ve got it in my list at Amazon.

My only complaint with all of them, is the need for a shorter optical wire. Maybe 3 to 5 feet versus 16 feet.
I bought one a couple years ago, that had promised but was difficult to set up/operate. I threw it away.
