- There are two types of high-end headphones. One is high-impedance and low-sensitivity headphones. The headphone output of ordinary devices of this type is difficult to drive. There is also a class of headphones with a low impedance and high sensitivity design. Such headphones have high requirements for the stability of the current output. In view of this situation, an amp is needed to improve the headphone output of the sound source to exert the effect of the headphone.
