What are the best portable headphones for sound quality designed for MP3 players?

[Daveb2012]

I have read that most MP3 players headphones are bad sound quality, I was wondering if any one would recommend a good set of earbuds/head phones under $50-60? I aprecieate any input. I would like to buy some thing asap.
