Make Noise Reduction Headphones for $20

You can head down to your local stereo store and get fleeced for about $150 (or more) to buy a good pair of noise reduction headphones; or you can watch this video demonstration from Metacafe on how to hack your very own noise reducing headphone set for around $20. You can find the headphones that the video talks about at any home improvement store—all together, this simple DIY project takes about five minutes (not counting your visit to the store). Definitely worth a try, especially since these things are so dang expensive.
