Headphone amplifier

A headphone amplifier is an external device that amplifies the electrical signal from an audio source before sending it to the headphones. It can be a crucial component of your audio equipment, especially if you are involved in professional audio production, as it can help to improve the sound quality, sound accuracy and volume of the output sound that you hear through the headphones.
In other words, a headphone amplifier can act as a powerful and necessary device to optimize and enhance your audio experience, whether it's for listening to music or mixing tracks.

For studio recordings, a headphone amplifier with multiple inputs and outputs is used to distribute and regulate one or more monitor mixes to the musicians in the recording room.
