An audio amplifier, often known as an amp, is an electronic device that increases the power of an audio signal. Amplifiers are used in a wide variety of applications, including home audio systems, public address systems, and musical instrument amplifiers. In the context of headphones, an amplifier can be used to improve the sound quality and volume of the headphones.
The Beyerdynamic Pro X M70 is a high-end pair of headphones that are designed for professional use. They offer excellent sound quality and are very comfortable to wear. However, they can be quite power-hungry, and as a result, they may not be able to reach their full potential when used with a low-powered amplifier.
