Newegg via eBay offers the Klipsch Image X5 Noise-Isolating Earphones in Black for $54.99 with free shipping. That's tied with our mention from two weeks ago as the lowest total price we've seen. (It's also a current price low by $53.) They feature armature technology, frequency response of 10Hz to 19kHz, 50" cable, five sets of tips, compact magnetic case, airline adapter, and cleaning tool.
