Tonal Profile

Worth putting side by side with the Superlux HD681 in this same batch: 50 mm neodymium driver, semi-open chamber, 10 Hz to 30 kHz, 300 mW maximum power, 32 Ohms, and a sensitivity printed in the same words — '98 dB SPL (1 mW)'. Six specifications and one phrasing in common is the signature of a shared original equipment manufacturer rather than of two independent designs, and it is the reason measurements of one tend to describe the other.
