Query: Great Radio But Replace the Headphones

Great little radio with less background noise than the previous M35 model. But do yourself a favor and ditch the headphones that came with it. Instead get the Koss Sportapro(~$30) and get dramatically better sound. It may seem crazy to spend as much on headphones as the radio itself but you'll be amazed at the sound quality when you do. The Sportapro gets great reviews and you can't do better for a $30 set of headphones--they also fold backwards in "street style" mode and keep out of your hair when exercising.
