I scrambled for a bit trying to find a sound card or USB audio device with optical out. I could only find expensive options. I discovered that my motherboard had optical out later, so all was well.Cue this year, I went with a smaller motherboard for my machine. My foresight and planning prowess came back to bite me though, and I found myself without an optical connection.This fit my need perfectly. I had been running the speakers using Bluetooth while I was waiting for this to come in, and the difference in quality was amazing.Setup is as follows: plug it into the computer, connect the optical cable, select "USB AUDIO CODEC" as your output, and you're done. No fuss.Build quality is great too. Feels overbuilt, quality connectors and hefty aluminum enclosure. ### ⭐⭐⭐⭐⭐ Works great for audio *by on Reviewed in the United States October 10, 2025* It worked right out of the box. I'm taking audio out of a micro PC USB port and connecting to my receiver's optical-in port. Music is great. I'm not experiencing any extraneous noises or any transfer issues. ### ⭐⭐⭐⭐⭐ Works Great! *by on Reviewed in the United States April 16, 2025* I'm using this item in a recording studio for plain ol' reference monitoring (no high-bitrate stuff), and it does the job perfectly. I've not tried the coax output, we're running just the optical. Seems pretty solid and indestructible. ## Frequently Bought Together - DSD TECH SH-AU01A USB to TOSLINK Coaxial Optical Audio Adapter - KabelDirekt TOSLINK – Optical Audio Cable – 1.5ft – Fiber Optic Cord, S/PDIF Digital Audio Optical Cable for Soundbar, Stereo Systems, Home Cinema, Xbox One/PS4 – Designed in Germany - FosPower Digital Audio Coaxial Cable [24K Gold Plated Connectors] Premium S/PDIF RCA Male to RCA Male for Home Theater, HDTV, Subwoofer, Hi-Fi Systems - 6ft --- ## 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.kr/products/511396325-model-sh-au01a](https://www.desertcart.kr/products/511396325-model-sh-au01a) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-08-21*
