J&R offers the Grado SR60i Prestige Series On-Ear Headphones for $54.99 plus around $6 for shipping. That's the lowest total price we could find by $18, although we saw them for $2 less two weeks ago. It features a soft adjustable headband, 1/4" screw-in adapter for use with professional equipment, and frequency response of 20Hz to 20kHz.
