Expert Audio Engineering Commentary

Tonal Profile

53 mm drivers in an open frame with the self-adjusting wing headband — no clamp to speak of, which is why the bass depends on how the cups happen to sit. 100 dB/mW at 48 Ohms is undemanding. Note that Audio-Technica names the unit here but not on the M20x/M30x pages: same catalogue, same year, two conventions.
