Review on Monoprice 108729 Keystone Jack TOSLINK Female 🔌 to Female Coupler Adapter, White, 1-Pack: Efficient Connectivity Solution by George Thorson

I used 2, one in each wall panel to hide the wires to my hanging TV. I couldn't line up the connectors properly to send the signal to my Bose sound system. I even bought 2 more thinking it was user error and maybe I distorted them when installing them in the tablet. Same problem. Again I thought it was a bad setup as I can see a red light on the other end, removed them from the wall plate and connected them in series from the TV to the Bose and they only worked when I held them horizontally. I ended up buying a 15 foot fiber optic cable, running it through the wall and fixing the connections. Problem solved. Haven't used them.
