For as long as it worked it was good with average sound but after about 2 years it started producing some high frequencies and stopped working. Buy something better with more money if you want something reliable

I connected it to the TV via the optical port and the RCA to a vintage amplifier. While at first the converter was working normally and I had plugged in a USB stick with songs and movies into the TV, it shorts the amplifier while playing songs, stops for a few seconds (if I turn off the amplifier and listen from the TV, they play normally) and then starts playing again. It hasn't done this with movies. The amplifier works perfectly with a turntable, tuner, and CD player without interruption. I do not recommend it for purchase. I have ordered another one from abroad of a different brand.

It does exactly what it needs to do. I have it connected with optical fiber to PS2 and there is not the slightest delay in the output, with clear sound without noise.

Decent product, ideally I would also like an adapter from USB to power, because otherwise you occupy a port from the TV.

It does exactly what it claims. I easily connected a modern OLED TV to my existing home audio system via the digital output using RCA. The result is excellent, without the need for soundbars or unnecessary home cinema speakers, and without wasting money. The sound quality from the speakers of the home audio system is very good, you can adjust the volume as much as you want, and it feels like you're listening to a CD or radio through YouTube. I highly recommend it if you already have a home audio system infrastructure.

I give it 3 stars because although it does what it promises quite well (Crystal Clear Sound), when using the device with the TV (LG) via Toslink, the TV does not have the ability to control the volume, which for me, if I had known from the beginning, would have been a deal breaker.

After researching how to achieve this on my TV, I will need to find a compatible device (Converter or Soundbar) that will communicate with the TV's software and Magic Remote.

I have not yet found such a Converter from what I have searched, and I am not interested in getting a Soundbar because my audio system, although analog, does its job well.

For now, I will stick with the Knob in hand.

(Caution with the power supply, I recommend a power supply with an output capability of at least 5V, 1A)

Value for money device! Along with the cables needed for connection, which you buy separately depending on the audio device you want to connect to the TV, I saved my 20-year-old home cinema and saved a significant amount of money by not buying a soundbar or other type of audio output device.

Excellent sound quality. The sound is comparable to much more expensive DACs...
It was connected with optical fiber at the source and the output to a Harman Kardon amplifier with Rolland cables. Balanced, clear, and detailed sound.

Very good sound but be careful, in my case the channels were reversed, meaning the left one had to be connected to the amplifier's right channel and vice versa. It played fine like that, but I realized it from the sound separations, they were reversed. Other than that, very good

It does all that it really promises, perfect for its price, and most importantly, no loss in sound quality. I recommend it 100%

The best by far!! It works even on a 5.1 home cinema sound system, it produces excellent sound from all five speakers and the subwoofer, don't even think about it..!

I have connected it to my SONY 55" television through the optical output and DENON amplifier, and it has very good sound quality. It is powered by the television's USB. The television has options to disconnect its own speakers or leave them with adjustable volume. The volume of the amplifier's speakers is adjusted by the amplifier itself. The quality of the box is very good and sturdy.

I use it to connect the optical audio output of my smart TV to a hi-fi amplifier. It receives power from a USB cable that is included in the package, which you connect to a USB port on the TV. Everything is fine.

It is worth it and more
There is a difference in sound, even in the low frequencies, especially in the bass if you have 5.1

I have been almost amazed by the product. I have tried 3-4 cheap DACs, and they all had their problems... This is the cheapest one I have purchased and it has better sound quality than DACs that cost five or ten times as much.
