I'm a developer (currently not a MAC one, if anybody wanna give me a mac, I can solve it ) and in my current house where I work the outside is very loudly. I can't move by now, but wanna reduce the noise levels. I know about noise canceling devices, but wonder which is the BEST way to reduce noise. The problem is that in the night the noise is high, bastard people around!. My budget <US 300.
