The Audio-Technica ATH-SR9 came in a great looking color printed box with photos and specs of the headphones. Opening the box I found a well protected product held by a semi-hard zipper case. Materials used in the construction was metal and plastic, and memory foam for the soft headband and earcups. Quality of materials used was very good, as was the fit and finish. Also included was the manual and two sets of cables, one standard and one with mic and music controls, and a ¼” adaptor.  Now lets hear how they sound!
