After resolving the problem, it turns out to be a very useful product to extend the length of a jack too small for example ...
And as this is a STEREO coupler (see two parallel lines visible on the slice), you can also extend your headphone cord (often too short), as long as you have a jack STEREO switching with this beautiful craft.
Anyway, as I said before, at the sight of the price: it can only do so!
