Why aren’t all music players built into headphones? Okay, don't answer that. The Sony Walkman NWZ-W260 is light, water-resistant for the sweatier gent, and even washable for the even sweatier fellow who wants to take a shower with music still blaring. There's also drag-and-drop music transfer and iTunes or PS3 syncing. The built-in Zappin software lets you build a playlist as you pound the pavement and, unless you're a marathon runner, it'll keep running longer than you can – a three-minute charge will last an hour. The fully charged cell goes for eight hours, plenty for even the most masochistic workout. Due at the end of July with a price to be announced.
