Didn't work. I had a set of headphones I used for my computer. They also worked on my TV, but of course the cable was too short. So I ordered the extension. At first the male part of the cable wouldn't fit into my TV, so I bent back the tabs. It fit then, but still wouldn't work. It only cost about $6 including shipping, so I didn't bother to return it. Also, since I had damaged it, they probably wouldn't accept the return.
