Headphone amplifiers with treble control

Treble adjustment

— the presence of a separate treble control in the amplifier.

This control allows you to adjust the volume of high frequencies separately from the rest of the range. Formally, it has the same purpose as the LF control (see the relevant paragraph) and differs only in the frequency range; however, in fact, HF adjustment has its own characteristics. The main one is that for most users, the quality of the high frequencies is not as critical as the quality of the bass; therefore, this adjustment is quite rare and only as an addition to the bass control, expanding the overall possibilities for frequency adjustment of the amplifier.
