Analog to Digital Audio Converter, Hdiwousp RCA R/L or 3.5mm Jack AUX to Digital Coaxial Toslink Optical SPDIF Audio Adapter for PS4 Xbox HDTV DVD Headphone (Aluminum)

UPDATE: After experiencing some unsatisfactory results with my W11 upgrade, I decided to roll back to 10. The volume is back to 2 bars just like it was with 8.1, so I added a 5th star to this review.After "upgrading" to newer hardware, I was missing my Dolby surround sound card that fed my Logitech Z-5500 for the last 20 years or so. The newer PC I migrated to only has a 3.5mm external jack, so there's no way I could plug directly into the Logitech. This adapter seems to work just fine, and since I no longer use my PC as a HTPC, I won't miss the surround setup at all. I do believe that there's some loss of volume though in the transition from analog to digital, as previously 2 bars on the Logitech display was plenty loud enough. With this adapter, I have to have it set a 4 to get the equivalent volume, even with Windows set at it's max.

This is a great device for anyone who needs to connect equipment that only has a 3.5mm audio output. I bought it to connect my projector, which doesn’t have an optical audio port, and it worked perfectly for that purpose.One tip to keep in mind, this might be obvious to some people, but it wasn’t to me: use a short 3.5mm cable and a long Toslink cable, not the other way around. At first, I tried using a long 3.5mm cable and a short Toslink cable to connect to my soundbar, and the audio was very distorted and almost unusable. I actually thought the device was defective.Then I reversed the setup, using a short 3.5mm cable and a longer Toslink cable to the soundbar, and the sound quality improved dramatically. Compared to running a 3.5mm cable straight from the projector to the soundbar, this converter produces much clearer, cleaner audio and eliminates a lot of the buzzing noise you sometimes get when no sound is playing.If you have a projector like the Epson Home Cinema 2150, which only has a 3.5mm audio output, and you want to enjoy digital audio without annoying background noise, I highly recommend this device. It’s definitely worth the price.

Great for now. Nice and easy to set up. Very straight forward. Couldn't notice a drop in sound quality of my Bose lifestyle 38 surround sound system which I had for more than a decade and a half. Will tell if am disappointed in the near future. Hopefully not...

One of the previous Bose speakers attached to my Echo Dot was blown. I had an unused high end Yamaha sound bar that I wished to attach to the Echo Dot. The bar required an digital optical connection. The Dot needed an analog 3.5mm connection. The converter worked, but the sound emanating from the beautiful Yamaha sound bar sounded like the speaker on a small cell phone. I have returned it and ordered speakers from Amazon.

It functions as an A-D converter but adds quite a bit of noise to the signal.

I needed something to convert an analog signal from my computer to an optical signal for my sound bar. The sound bar only comes on automatically when there is an optical input. this device does what it says it will do. My only complaint is the cords provided (optical cable and ac cord) are pretty short which limits your options for where you want to place the device.

Did exactly what it said it did. Used it to hook a turntable with RCA outputs to a high end soundbar system that only had optical and HDMI inputs. Took 2 minutes to install and the sound was gorgeous, signal strength was great. Actually sounded better than it did through my mid range amp system. The included cable did NOT fit the sound bar and didn't really fit into the adapter though. I don't know the difference between TOSLINK and standard digital optical, but I had to use another standard Digital Optical cable for it. The one that came with it would sit in the adapter and slide out (same on the soundbar). Looked the same as a Dig Optical cable for the most part, but was pretty much worthless.

Hooked up from RCA tv to optical to sound bar. Right off the bat works good and sound quality is great. We'll see how long it works for.
