Make better earphones with noise cancellation

Cool.

I have these Bob Marley headphones and they work perfectly at blocking sound

SMH. I whole generation of deaf people.

The Sony noise proof headphones work just as well...the only side effect is that you can't hear when someones calling you...(aka. Mum)

Clever, but not noise canceling.

I'll stick with mine thanks. Though I want to try this.

So much "thats what she said" I canot take it.

You really shouldn't wear headphones/earphones when you are going out as you wouldn't be able to hear what's going on around you, which will obviously lead to accidents.

I work in an engineering factory, I'm totally doing this.
