Awww, will you look at that? Brought to you by a company named Newman (not to be confused with Newman, left), it’s two halves of a heart-shaped MP3 player exchanging a tender kiss.
You and a loved one could exchange your own tender kiss before work, split the MP3 player apart, and each listen to your half on your separate trains. Then when you get back home, reattach the two MP3 players to become one passionately-beating, music-thumping heart again.
Details beyond that are scarce, except that I think this right here might be the product page (my Chinese is a little rough non-existent).
