Look, it's a shortish adapter cable - there's not much more to say. It looks to be well-made and it works fine with no noticeable noise. However, note that the 1/8" cable does not work well into Apple 1/8" sockets: They are designed not to grip non-Apple plugs, which need a beefier (i.e. larger diameter) plastic case to fit tightly into the socket. That's not the cable's fault, it's Apple's...
