Jaybird's Run headphones aren't meant for you to stick them in your ears and forget about them. They're not ear-puters. Like all Jaybird headsets, they're made for runners, and I guess all exercisers, but mostly runners. They're designed to stay put in your sweaty ears for a whole trail run, blasting music until you've crossed the finish line. For $180, they'd better shave some serious time off your personal best. The Runs pump out rich, detailed sound, especially punchy in the low end.
