Guitar Center offers the AKG K 44 Studio Over-Ear Headphones for $15. Opt for in-store pickup to dodge the $5.39 shipping fee. That's $5 under our April mention and the lowest price we've seen. (It's also $30 under the best shipped price we could find elsewhere.) These closed-back, circumaural headphones feature a self-adjusting headband, gimbal suspension, and leatherette ear pads.
