Amazon now has these Sennheiser HD201 Circumaural Headphones on sale for just $18.28, the lowest online. These are well reviewed, with an average rating of 4 out of 5 from over 300 buyers and come with both 3.5mm and 6.3mm gold-plated jacks. I use these at the BradsDeals offices and have found them to be a great value. Shipping is free with $25 and there's no sales tax (except KS, KY, ND, NY, WA).
