The dark sound signature, as you guessed, is the exact opposite of the bright sound signature. It enhances the lows (bass and sub-bass) and reduces the highs (treble) to give you that extra punch in your music.

Bright or Brightness is a term usually associated with treble or the higher frequencies. It makes the highs peak out, thereby making your audio sound more entertaining and enjoyable. Most music enthusiasts love bright sounding headphones, however, if overdone, your music can sound terribly sparkled.

“Bright” is the opposite of warm. Bright gear is better at reproducing high-pitched sounds. You'll see phrases in reviews like “Sparkle,” “Crisp,” and “Clarity” used to describe bright gear. Bright headphones are sometimes valued in production for their ability to reveal hisses and other imperfections in recordings.

• A bright sound has most of the spectral energy in the high frequencies. It is often a high-pitched sound that can be composed with a sharp attack. • A warm sound tends to be a low-pitched or mid-low-pitched sound.
