I got this cable as a work around to always having to carry a great number of adapters.
It lasted less than a year, with the connection on the Mini Jack side breaking contact, hissing and finally not passing through any sort of audio signal.
I took it apart to figure out what had happened.
Turns out the connections are as flimsy as they come, with just about 2 strands of thin wire making up the connection. The Mini Jack side of the wire broke off.
Impossible for me to actually repair as the wires are just too thin, it is now useless and a complete waste of money.
Terrible cable, stay away
