T-shirt and music player, those two are complements each other, but absolutely not for substituting. Yet, crazy idea may come from everywhere, especially from creative minds of The Big Bang Theory creator. Meet the Personal Soundtrack T-Shirt. Initially appeared in The Bing Bang Theory Season 3 Ep. 16, entitled The Excelsior, Folks at ThinkGeek really want this mix-crazy-and-cool thing to be wore by any geek in the world.

The “magic” lies at speaker and wired remote implanted into this shirt. With this thing, people who wear this tees are able to play their own music playlist, even without bringing a dedicated music player. What’s the use of portable music player if you have already had it inside your shirt? Completing its coolness, it has own SD memory to store various mp3 songs of your choices.
What about the energy to run the player? Don’t worry, you don’t carry a boom with you. It is powered by 4 AAAA batteries that are easily found in market near your place. With all this stuffs loaded into this shirt, don’t you think US$29,99 ($39.99) price tag is too cheap?
