Azduou Optical-to-Coaxial or Coax-to-Optical Digital Audio Converter Adapter, Bi-Directional Coax Digital Audio Converter, Digital Coaxial to Optical Converter

Works exactly as promised. Simplified connecting our TV with S/PDIF (RCA-style) Coaxial Digital Audio Output, to a sound bar with Toslink-style Optical Digital Audio input. Set-up took very little time and effort. However, It would be helpful if the description mentioned that the device requires a free USB connection for the power. It does show the connector to plug into the back of the device is a micro USB connector, but it does not indicate the other end is a standard USB connector with no adapter for an AC outlet.

Works as intended. Came with the cords coaxial and optical. I didn't expect that and now I have extras.

Works well for my needs

I needed this to connect one of my PCs to a Logitech Z550 with 3 digital inputs where optical and 2.5mm were already used. Plugged optical to this device and coax to Z550. Works fine with no issues.

As described with no issues as of yet
