The wider the frequency range, the better the sound
Headphone companies love emphasizing the wide frequency range of their products. The common understanding is that the bigger the range, the better the headphones sound. The human frequency range is 20Hz to 20kHz, and anything that doesn’t lie within this range isn’t audible to us. Hence, an overly exaggerated frequency range on headphones, such as 5 to 33,000 Hz, should make no difference to us.
These inflated ranges are of little use to us and don’t say anything about performance between the two frequencies. Sean Sullivan claims that specific info on the amount of energy the headphones produce within this range is more valuable. He adds that it’d be ideal to know how much power is made between 100Hz and 10kHz since our ears are most sensitive to that range.
