## Description

desertcart.com: SYNCWIRE Optical Cable for Soundbar 3.3ft [24K Gold-Plated, Ultra-Durable] Digital Optical Audio Cable for Home Theater TV : Electronics

Review: It works. The cable enriches the sound experience - My soundbar system had a weak sounding treble and it would not adjust louder. I replaced the optical cable provided with the syncwire cable and the treble was boosted up. I then lowered the already rich bass a little and now I have an even sound. The cable is quality made (twice as thick) and the connectors are beefy and yet they fit. The cable has a quality look and feel. It's a value for the money. The plastic see through covers on the connectors offer protection and are tethered to the cable so you can cover them again if it's necessary.
Review: Works great - I bought and LG sound bar. It came with a thin junk Audio cable. I hooked everything up and of course the sound bar would not work. I started to think I got a faulty sound bar, and should have went with the Sony, but that thin POS Audio cable looked suspicious. Before attempting to disconnect and haul the sound bar back to Costco for a refund, I order this audio cable to see if my suspicion was right. I hooked this audio cable in, and Boom, huge sound coming from my sound bars. Works great, and still working. Quality looks good too. More than double the size of my included LG one, and with the gold tips. Very sturdy. If you need an audio cable, don’t hesitate to get this, even though it is a few dollars more that that desertcart basics and other cheapies, you get what you pay for with this.

### ⭐⭐⭐⭐⭐ Best Value Toslink Cable
*by D***K on May 12, 2022*

I needed new Toslink cables to reconfigure an optical audio patchbay in my studio, so looked around for a couple of days reading specs of the various cabling generally available. Specs were audio quality, cable build quality and of course price points... in that order. These cables made the 'short list' for purchase due to the price (obviously) and the perceived quality from the description and product images. Ultimately, I purchased these cables with the mindset that these were well constructed at a very good price point... only question would be the audio quality for obvious reasons until I could actually test and listen for myself... And they did NOT disappoint - hence the 5 star rating. Upon receipt and unpackaging, it was apparent right away they were robust with nice fitting connectors. The 'rubberized' cable outer jacket is extremely rugged and should last the test of time. They're also easy to work with, not too stiff as to present issues when using cable management accessories. The audio... when testing it was stellar with extremely LOW latency, exactly what I was after. Verdict for me, these check ALL the boxes on my requirements list and I'm sure they'll work for anyone doing audio and/or video work. Great 'Bang for the Buck' factor and I'm glad I found them... as I'll be purchasing 6-12 more in the near term future.
