Crushing who's skull?

I bought these headphones thinking they would be cool. I mean sub-woofers right on your ears. I overlooked one thing the sub-woofers are "vibration sub-woofers". They make your ears go numb and feel a bit itchy. The headphones are fairly quiet, and are very flimsy (the subwoofer broke within a week). I do not recommend buying these unless you are in for the experience of having a pair of vibrating headphones.
