You think that your headphone’s loudspeaker is not loud enough? If you wished to make the sound even louder, then you must be interested in this DIY Headphone Amplifier.

Before that, you should know some important details about the headphone amplifier. The headphone amplifier is one of the types of audio amplifier, where it’s designed to drive headphone. You can find the headphone amplifiers embedded in electronic devices, such as integrated amplifiers, portable music players (MP3) and televisions.

Most of the headphone amplifiers provide power between 10 mW to 2W, where it depends on the specific headphone being used and the designation of the amplifier! Technically, a headphone amplifier is a palm-sized power amplifier that can be connected to a standard headphone jack or the line output of an audio source. The headphone amplifier will improve the sound quality, by simply increasing the amount of power available to move the transducer. Furthermore, it enhanced the control that the source has over just where the transducer is in space! This whole process is known as the “damping factor.”

The advantage of using this palm-sized DIY headphone amplifier is it can act as gain enhancer for your gainclone when you’re watching movies from PC!
