Bose In-Ear Headphones give you the ultimate listening experience whether you are riding the A train, or rounding your 5th mile at the Reservoir in Central Park. We've all tried to get our triathlete on while listening to "Touch the Sky", but get caught readjusting our headphones every 2 minutes due to sweaty inner-ears. These headphones not only simulate surround sound, but they're comfortable and will stay in place. What's more is they come with 3 different sized removable tips to ensure a perfect fit. For about 100 bucks, you can round that 5th miles without any interruptions. Go to http://www.bose.com/ for more info.
