Newegg offers the Sennheiser HD 518 Over-the-Ear Audiophile Headphones in Titan for $44.95 with free shipping. That's tied with our mention from three weeks ago as the lowest total price we've seen. (It's the best deal today by $12, although most retailers charge $70 or more.) These open-back circumaural headphones feature a 14Hz to 26kHz frequency response, Duofol diaphragms, aluminum voice coils, and 10-foot cord.
