eSynic Portable Optical to RCA Converter with Volume Control 192KHZ Digital to Analog Audio Converter 7ft/2.1m Optical to Analog Audio DAC Converter Support PCM Audio Output for HDTV Blue-ray PS4 etc

I have no idea what this is needed in the car. Hubby was happy so am I.He said easy to set up, and connect, and control and value for money.

To improve sound quality of wall fixed TV, as usual TVs have small speakers and amps.I wanted a better, clearer, sound, perhaps I'm going deaf but don't want to admit it.Anyway old 15 yr old tv sounds much better now.

Does the job what it’s designed to do

I had no problem installing this to a very complicated hifi set-up a customer had. Connection was straightforward, perfect functionality, great build quality and value for money. I'd definitely buy again.

I now get great quality audio through my stereo. Just a couple of things to be aware of, in case you don't already know how this works:It does require a power supply from a USB port (I've used one in the TV) but the power cable is supplied.You may need to configure your TV audio output format, but instructions are easily available for most TVs

Good Quality

I use this to take the digital optical out from my TV and convert it into analogue into my amp. When the TV is on it works fine, but when the input is off it does have a fairly quiet whine / static hiss, this is enough that it means my amp things it's still getting a signal and doesn't turn off automatically.

looked to be exactly what i wanted when it arrived. connected it up and yea! sounded fine. wanted it to play my sky q box through my stereo system (i'm blind and don't use the tv as i can't see the thing, and proper speakers sound better anyhow). 24 hours later, sound was badly distorted. tried different cables i had, even different speakers, but no joy. so back it went for a refund. and bought an alternative device that is going strong still 2 weeks later. guess any device can go wrong, but inside 24 hours is a bit extreme.
