I use a pair of Apple Earpods as my jogging headphones, and they're quite decent for R300. They have two drivers, and the inline mic controls are the business if you're using an iPod.
Otherwise, give Saint_Dee a shout. The man is a headphone guru.
Good earphones in this price range is a tough thing to get. Earpods are good but you should probably look around and see what type you like (As in what they look and feel like).
