My Sony Sports headphones recently stopped working. The left channel keeps cutting out.

I need to pick up a good set of headphones for running & working out. Any recommendations?

I need them to be weather & sweat resistant. My budget is $20 -$40 since these will get thrashed around.

You should try the Koss KSC-50, KSC-55, or SportaPro (whichever style of headphone you prefer (they're all based on the same driver which means they should sound the same)). They sound great (especially if you can use an EQ to lower the midbass) and they come with a lifetime warranty so you can have them replace or repair it for $6 if you ever break them.
