Please do not show sympathy to people selling buds on roadside or at Signals. Just wanted to warn you people not to buy those packs of ear-buds you get at the roadside.
It's made from cotton that has already been used in hospitals.. They take all the dirty, blood- and pus-filled cotton, wash it, bleach it and use it to make ear buds. So, unless you want to become the first person in the world to get Herpes Zoster Oticus (a viral infection of the inner, middle, and external ear) of the ear and that too from a cottonbud, DON'T BUY THEM!!
Use Branded Ear Buds only to stay away from any such Possible Problem..
