Adorama offers the Sennheiser HD7 DJ Closed-Back Professional Over-Ear Headphones for $119 with free shipping. That's $5 under our mention from December and the lowest total price we've seen. (It's a current low by $131.) They feature an 8Hz to 30kHz frequency response, 95-ohm impedance, swiveling ear cups, coiled and straight detachable cables, leatherette and velour earpads, and protective case.
Dollar stores lure us in with their rock-bottom prices, but not everything is a bargain. We suggest you steer clear of these items.
