Sennheiser's headphones stay in place everywhere you go, while Solio's
charger soaks up the sun
During the summer, I'm usually on the run all day without ever coming home for a pit stop. That's not a big deal, except sometimes my devices can't keep up with me. But Sennheiser's MX75 headphones ($50), part of its new Sport line, are up to the task. Not only are they durable, sweat-resistant, and lightweight; they're also amazingly comfortable.
