The cables are very flexible. They are covered with what appears to be a nylon braiding. The cables are much thinner that is usually expected. I am using them to connect my Bose Mini-Link speaker to a small TV to improve the sound. The cable is doing its job. At this level, you probably could use baling wire and get some decent sound. So I am unable to attest as to the transmission capabilities of these cables. They serve my need and that is all that is important at this point. They are good for what they are.
