I predict that as cellphone users get younger and younger, it will be only a matter of time before the Plugys Earphone Jack takes off. Plugys Earphone Jacks are little cellphone charms that you insert into your, you guessed it, earphone jack.
The purpose of the charms is to let you customize your smartphone, and to keep you from getting dirt and dust in your earphone jack. The Plugys Earphone Jack comes in several different styles such as a water faucet and a mushroom.
While I can't see adults latching onto something like this, I can see kids eating it up. More and more youngsters will be getting their hands on smartphones in the coming years -- after all, you don't just throw out your iPhone 3 when you get the iPhone 4 -- which means there may be a huge market for accessories like the Plugys Earphone Jack.
