Sennheiser RS 220 in my living room rig, which consists of a MacBook Air (2011 13"), Fostex HP-A3 DAC/amp, AudioQuest Forest optical cable, and Sennheiser RS 220 wireless headphone system. The drumsticks belonged to Alex Van Halen, and were given to me by Jerry Harvey of JH Audio, at a Van Halen concert (February 20, 2012, in Detroit) for which Jerry was the monitoring engineer.
