## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great
*by T***R on 11 February 2025*

No issues at all, needed this as I bought a soundbar which has optical connection only and use a gaming monitor with VRR which has 3.5mm out only for audio.Xbox series x has no optical out and when using a HDMI audio extractor you would lose the ability to use VRR (Variable refresh rate) which is what i experienced and couldn't get used to the downgrade.With this item i am now able to connect the xbox directly to the monitor with a HDMI cable to keep VRR and I use the linkfor adapter to connect from the 3.5mm out of the monitor to the optical in on soundbar so really happy about that as if you've tried gaming with VRR and without there is a noticeable difference with framerate drops and stuttering.Easy to set up, sound quality is unaffected and cable length is good.

### ⭐⭐⭐⭐⭐ Good product
*by W***S on 30 July 2025*

Works well good quality does the job

### ⭐⭐⭐⭐ Convert digital coax output to optical easily to connect a soundbar to TV
*by S***5 on 19 July 2024*

This is a great little product allows use of a soundbar with optical input with a TV/DVD with a phono digital output.Powered by USB, plug and play, the only drawback I have found is with my cheapo soundbar there is a short burst of white noise when changing sound modes. otherwise OK.
