These are later versions of Beats popular wired headphones. They feature metal sliders in the headband that are much sturdier than the plastic ones in their other models. The audio cable is permanently attached, thereby eliminating a common failure point-the audio jack.
These headphones are in good condition with very little wear on the ear and headband cushions. I have replaced the stock molded plug with a metal one made by Sennheiser for increased reliability. There a plastic insert on the left side that is missing (see photo).
Included with the headphones is the original cloth pouch for storage.
