Sennheiser MX75 Sports Headphones

The problem with working out with most headphones (like those notorious iPod earbuds) is that they are too flimsy, and pop right out of your ears at just the wrong moment, like when you’re looking both ways before crossing the road. Sennheiser’s MX75 headphones are built especially for working out, with rubber stoppers made to keep the headphones securely in your ear where they belong. There’s also a great “twist-to-fit” feature, and a heavy duty cord that can take the pounding your last set of phones couldn’t.
