Technically, these aren’t headphones. They’re wireless mini-speakers. But by functioning as a personalized stereo around your head, they help you stay present while reducing disruption to others that comes from blasting a stereo (and who’s going to run with a stereo?). Secure these to your shoulders on the outside of your shirt using the small magnets provided and you’re ready to rock. Listen to your tunes or take a call while you run while ensuring your ears are free to pick up critical sounds like bicycle horns, traffic signals, and ice cream truck jingles. Just be aware that your music is audible to others, so these aren’t the best choice for the office or public transportation.
