Over the weekend I lost most of my hearing in one ear due to earwax buildup. For reference, I am 25. Today I went to the ear doctor to have him vacuum out both my ears with a tiny straw and a microscope. It was Awesome 
Now, not only is my hearing back to where it was before, it's improved tremendously, especially in the higher frequencies. I'm listening to my lowly Porta Pros and an entire new sound register has opened up. They sound like $300 cans now. My junk bin car stereo has also gotten a hi-fi upgrade.
Best $85 I've ever spent on audio equipment!
