Why? That's my biggest question. How could the brains behind this idea even think to pair headphones with a bottle of vodka? I wonder if it is a new MP3 player shaped like a bottle of vodka and full of vodka, I'm guessing that you plug them into the cap. Sure, it looks cool, but I don't see the point (it almost looks like a nicer version of the new theft deterrent system that one of the stores near my house is using).
If anyone living in Taipei needs a new pair of headphones and a quick way to get smashed, I guess this is the place to go.
As one of the commenters put it, "Absolut iCrap".
I think attaching a shot glass to the top would have been a better combo.
