DESIGN AND CONSTRUCTION OF HEADPHONE AMPLIFIER
ABSTRACT

Headphone amplifier drives headphones instead of loudspeakers. Most commonly they are found embedded in electronic devices such as integrated amplifiers, portable music players and televisions, but standalone units are not uncommon.
Headphone amplifier can provide the voltage levels necessary to drive the headphones. Most headphone amplifiers provide power between 10 W and 2 W depending on the specific headphone being used and the design of the amplifier. Certain high power designs can provide up to 6W of power into low impedance loads, although the benefit of such power output with headphones is unclear, as the few headphones that have sufficiently low sensitivities to function with such power levels will reach dangerously high volume levels with such amplifiers.
