I was getting tired of my headphones falling out of my ear mid-run every 2-3 minutes. I was tired of fiddling with my headphones throughout my run.
I have gone through 3 or 4 different types and styles of headphones, and finally found some that I absolutely love. If your looking for some great running headphones, you need to check out the Sennheiser PMX-70 Neckband headphones.
They have an arm that goes around the back of your neck, they stay in your ear great, and they sound awesome. I was tipped off to these through the Runner's World forums, got some, and tried them out today on my 6 miler. I couldn't be happier, these headphones are great. There is your consumer tip for the day!
