HeadAmp Pico Power Portable Headphone Amplifier

Our Take

Pico Power is our “no-compromise” portable amplifier—built for listeners who want desktop-grade drive in a genuinely travel-friendly form. The high-voltage design and discrete output stage give it the headroom and control to stay composed with difficult headphones, while the three-way gain switch makes it equally at home with sensitive in-ear monitors. If you travel or just want a small-footprint amp that still feels serious, Pico Power is a great fit.

Power & Control

Pico Power delivers 18V of portable power and a discrete output stage designed to maintain authority across a wide range of loads. An ultra-low 0.2Ω output impedance—lower than many desktop amplifiers—helps keep bass tight, improves damping, and supports consistent frequency response across different headphone impedances.

The three-way gain switch lets you tailor the amp to the voltage needs of your headphones: from high-sensitivity IEMs all the way up to high-impedance studio models in the 300–600Ω range.

Battery System & Build

Pico Power uses a dual, user-replaceable 9V battery system. You can run common alkaline batteries, environmentally-friendly rechargeable cells, or long-life lithium batteries depending on your listening habits and travel needs.

The chassis is precisely milled from a solid block of aluminum for an extremely solid build that’s made to hold up over years of use.

Pico Power includes two 9V alkaline batteries and a protective leather amplifier case.
