SOUND! Worked perfectly. There are instructions if you need it. Silly me plugged the USB into the sound bar thinking that would power it 😅 read the instructions, you need to connect the USB to a plug. Maybe I'm just stupid, but it might help someone. Review: Great with Sonos Beam soundbar - I needed a solution to connect my speakerless monitor to my Sonos Beam soundbar via the monitor's 3.5mm audio output socket. The Sonos Beam only has an HDMI input but is supplied with a SPDIF to HDMI adapter cable. To be honest, I had quite low expectations for this LINKFOR analogue to digital converter based upon some of the reviews. I, however, can't fault it. The sound quality from my Xbox Series X via the monitor and LINKFOR converter is great with no whining or high pitched noises as reported by others. Easy to connect and good quality for the price. One happy customer who would have no hesitation buying another. ## Features - 【By LiNKFOR - 3.5mm to SPDIF Audio Converter】Convert the 3.5mm Jack AUX Audio to Digital Optical or Toslink SPDIF 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. ## Frequently Bought Together - LiNKFOR 3.5mm to SPDIF Converter Analog to Digital Audio Adapter for Enhanced Sound Toslink Optical Output 3.5mm to Optical with Optical Cable for Amplifiers & Soundbars - PROZOR 192KHz Digital to Analog Audio Converter DAC Digital SPDIF Optical to Analog L/R RCA Converter Toslink Optical to 3.5mm Jack Adapter for PS3 HD DVD PS4 Amp Apple TV Home Cinema - LiNKFOR 192kHz DAC Converter Digital to Analog Converter Digital Optical SPDIF Toslink to Analog Stereo Audio RCA L/R Audio Adapter with Optical Cable for HDTV Blu Ray DVD Amps (RCA Male) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/610271810-linkfor-3-5mm-to-optical-converter-analog-to-digital-audio](https://www.desertcart.tn/products/610271810-linkfor-3-5mm-to-optical-converter-analog-to-digital-audio) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-19*
