## Description

LiNKFOR 3.5mm to Optical Converter - Analog to Digital Audio Converter with Optical Cable for HDTV Projector PC to Soundbar : desertcart.co.uk: Electronics & Photo

Review: Works great - 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.
Review: Resolved connectivity PS5 to JBL soundbar - It worked as expected and able to connect PS5 to a JBL sound bar!

### ⭐⭐⭐⭐⭐ Works fine
*by M***S on 24 October 2025*

I had my doubts but this is great for connecting an old CD Player to a modern set of speakers. It does require USB power. Cable length is excellent with a LED indicator so you know it is powered. Just what I needed.
