Headphones with extended frequency range

Extended frequency range

— the perceptual standard of the human ear is 20 – 20,000 Hz. However, ideally even less. However, a wider frequency range has a beneficial effect on sound quality. It's not that you'll hear additional notes, they'll just sound completely different, smoother, with less distortion. Therefore, an appropriate filter allows you to separate classic headphones with a range of 20 - 20,000 Hz and select somewhat more advanced ones.
