Does It Pew shows you how you can take a cheapo pair of $30 headphones and turn them in a set that gives you the same quality sound that you might normally pay $300 for. Basically you gut a standard pair of cans and swap in these SFI tweeters. Don’t be thrown off by some of the terminology on Stacy’s post, you’ll need to be handy with a Dremel but this is actually a pretty easy and fun DIY weekend project.
