What is this? What does it do?

My brother got me this for Christmas. I'm just copying the name of it from eBay.

1pc 1/4 Male Stereo Phone Plug Headphone Cord Amp Amplifier NEW

I'm unable to find out what it does and can't find anything about it online. Some one please help! What does this thing do?

My guess is that it would allow you to plug a headphone size input into your amp sized input or perhaps vice versa. Not sure what the use for plugging a headphone sized jack into your amp jack might be but??? I could be completely wrong though. Good luck with the search.

If it's this, you could replace a faulty 1/4" stereo plug on you headphones with it.
