Query: Not Good For Running

I've been using these headphones for two weeks now. I like to listen to music while jogging; typically no longer than 4 miles at a time. The headphones are comfortable (at first), they stay in place, and sound great, but they don't work out well if you're going to be sweating.My right ear will fill with sweat, creating a suction cup effect with the headphone, this is INCREDIBLY annoying. Its just the right ear, the only thing I can think of is that the cord coming out of the left headphone pulls that side down, allowing sweat to funnel out on that side, thusly pulling the right side up and not giving the sweat anywhere to go.I really wanted to like these headphones; they will jump to the top of the non-running headphone rotation, but just another pair in a long list that doesn't work out for jogging.
