When PSB’s Paul Barton recently called me to chat about headphone measurement, it soon became apparent that he’d read every scientific paper ever written about headphones. The first headphone to which Barton brings his ultra-scientific approach is the M4U 2, a noise-canceling model poised to go up against the likes of the Bose QC15.

Maybe back in the 1920s, when Sound + Vision was called Superheterodyne Journal, we might have reviewed some giant tube amplifier that put out 2 watts at full blast.
