Review: Sound Quality Is Superb - This device works very well. My new PC had no SPDIF Optical out. Plugged this into a USB port and I now have crystal clean 24 Bit audio to listen to my music on the BIG speakers and my AV Amplifier. It's a more cost effective option than installing a PCI card in the computer. One minor issue: The first one I ordered had a short in the USB cable. The sound would stop under the weight of the Optical cable plugged into it. Hanging there caused a short. Must be manufacturing issue. Given the reasonable price, I just bought a second one and it works fine. Now I have two. One as a spare I guess. I can get the bad one to work if I hold up the cable in a manner to take the weight off the USB connecter. Strange issue, but I didn't bother to send it back. The cost of shipping wouldn't be worth it. It's a great product but needs better quality control in manufacturing.
Review: Great Little Adapter, Huge Sound Difference - I picked this up to improve the audio quality from my PC to my Samsung HW-S50B soundbar. Bluetooth just wasn’t cutting it, the sound was hollow, lacked bass, and didn't use the center speaker at all. This inexpensive adapter completely changed that. It was plug-and-play on Windows, I just had to switch my sound output from Bluetooth to SPDIF and I was good to go. Now I get clean, full sound with strong bass and much better center channel clarity. Movies and music actually sound how they should. Build quality feels solid too, no signal dropouts, and the optical connector fits snugly into my soundbar. The price is excellent for what it delivers, especially compared to some of the overpriced alternatives out there. If you're looking to squeeze better sound out of a setup that supports optical input, this adapter is a no-brainer over Bluetooth.

### ⭐⭐⭐⭐⭐ Plug and play! Great for Laptops or adding DAC support to PC
*by D***S on June 10, 2026*

This works fabulously! Had to replace my 11yo PC build and lost the onboard SPDIF port I use to connect my DAC/Headphone amp. Only other alternative is a $100+ PCI card with ton of features I wouldn't be using. Saved a lot of money, and works great. Flawless installation, and Just Worked with Windows 11. No configuration needed other that switching Audio Output Device in the Sound settings. Highly recommend if using DAC with a laptop or any PC that doesn't port onboard.
