20 Best Headphone Amp Under 100 (2023 Updated)

A headphone amplifier is a device that takes a weak audio signal and amplifies it to a level where it can be used to drive headphones. Headphone amplifiers are used in a variety of applications, from portable music players to high-end home stereo systems.

While there are many different types of headphone amplifiers on the market, they all share one common goal: to provide clean, clear sound at a reasonable volume. Headphone amplifiers typically have one or more audio input ports, a volume control, and one or more headphone output ports.

Some models also include features such as tone controls, bass boost, or other sound-enhancing options.

Headphone amplifiers can be powered by batteries or AC adapters, and some models even include USB ports for charging your headphones. When choosing a headphone amplifier, it’s important to consider the type of headphones you’ll be using, as well as the amplifier’s power output.

Most headphone amplifiers can drive any type of headphones, but some are designed specifically for high-impedance headphones or in-ear monitors.

If you’re looking for a great headphone amplifier under $100, there are many great options available. Some of our favorites include the FiiO A5, the Schiit Magni 2, and the Topping A30.
