Only have used the product a handful of times since purchased back in early 2020. Unfortunately the audio seems to produce a gradual crackling sound until it completely cuts out entirely.
Do yourself a favour and purchase a different set of cables. I gave the product two stars because I had no complaints with the visuals (although you can get better quality elsewhere - you get what you pay for)
The cables work well when they actually work and if you're looking for a cheap alternative to connect your system to your TV. Hopefully if you purchase these cables you don't run to this issue as it seems a good amount of people experienced this same problem.
