This update to Belkin's classic Stereo Link Cable ($15) now uses a smaller, iPhone-compatible 3.5mm headphone plug in addition to the nickel-plated contacts and chrome-finished bodies we've seen in past Belkin cable designs. RCA-style left- and right-channel stereo connectors are at the other end. Six feet in length, the cable's designed to let an iPhone, iPod or other audio device connect to a stereo system.
