is an excellent site for this, it has a wizard and all. It's aimed at audiophiles but has some cheaper stuff too.
You'll not get anything great for $50, not near it, but you can get decent for $50. You can spend $10K on headphones if you're crazy. I have Sennheiser 280 Pro headphones which I quite like, but the bass is a bit light (but very low), and the treble's a bit harsh, and after 2-3 years the headbands crack. $100 or so I think. With a good EQ they work well, I use them at home all the time. I use Audio-Technica A900s as my headphones at work, they're great, well ballanced, but quite large and US$200. Lately i've been using Creative EP-630 earbuds at work, i'm quite impressed given their cost - < US$50. If you get 630s try and find the model with asymmetrical cord lengths. Koss has a good reputation for your price range.

Not really. Unlike a wife, you can turn the headphones off, however.
I dunno, I think you can turn a wife off, but not in the way you mean
