Bought off Amazon for 120+tax Lightly used for 6 month for online meetings, selling as I'm no longer work from home. The build quality is quite decent for the price, and it does have a metal hinge. Sound quality wise think of it as a closed-back hd560. The headphone also has 2 sliders on top of the headband for clamp-force adjustments, which is quite useful. Near new condition, comes with all original accessories (3.5 cable for mobile devices + audio/voice split cable for PC) & original box 80 obo
