Newegg via eBay offers the Philips HiFi Precision Over-the-Ear Headphones, model no. SHP9500, for $59.99 with free shipping. That's the lowest total price we could find by $15, although we saw them for $14 less in August. These open-back headphones feature 50mm neodymium drivers, a frequency response of 12Hz to 35kHz, and a 10-foot cable.
