Update #2: Sold out! Product delisted at Dell Home.

Dell Home is today offering the Logitech Metro.Fi 150v iPhone Earphones for only $19 shipped, which reflects a $50.99 discount off the suggested retail list price and the lowest total price we know to be available by a wide margin.

As described, "It features integrated voice functionality and is specifically designed for use with the iPhone (and other mobile music phones with the same headset jack). With a miniature high performance microphone for hands free phone calls, this headphone has an in-line multi-function button to answer and ends calls as well as controls music/video on your iPhone."
