I run and bicycle on alternate days in gross humidity, and I have been using the "resting on the back of the neck" design of the Philips/Nike Flite Sport headphone for ten years: https://www.amazon.com/Nike-HJ020-headphones-Discontinued-Manufacturer/dp/B0009MFKDQ https://www.amazon.com/Nike-HJ020-headphones-Discontinued-Ma... For bicycling, I am mainly on bike paths but when I have to enter traffic for a bit, I would never, ever ride with any kind of ear bud or closed headphones. The Flite design has gentle pressure pushing the phones against my ears, for a very open design that keeps me aware of what is happening around me. They are very stable, resting on the back of my neck, even while running. I don't remember them every falling off from exercise. The original Flite headphones were somewhat overpriced, and lasted about a year before they failed. The Chinese clones moved in and the price collapsed. I bought a batch of ten knockoffs for $17 a few years ago, and they still last a year or so. http://www.ebay.com/sch/i.html?_nkw=sport+headphones+behind+neck&_sacat=0 http://www.ebay.com/sch/i.html?_nkw=sport+headphones+behind+...
