How we ranked these headphone amps
Every pick ranks in Amazon's best-seller list for its category and has a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.
- Built-in DAC weight 2
- Balanced output weight 1

Buying advice: headphone amp for soundstage
Match the amp power to your headphones
Output power decides whether an amp drives demanding headphones with headroom to spare. The Fosi Audio ZH1 delivers up to 2300mW, and the Schiit Gunnr delivers up to 2000mW RMS per channel, so both suit high-impedance and planar magnetic headphones. The beyerdynamic DT 990 Pro carries 250 ohm impedance, ideal for dedicated headphone amps and pro studio interfaces. Check the impedance of your headphones first, then pick an amp whose output covers them.
Use soundstage controls to shape the image
Some amps let you adjust the soundstage directly. The Schiit Gunnr has Width and Presence knobs that expand or contract the soundstage and enhance specific sounds. The Fosi Audio ZH1 takes a different route with Smart PEQ, where you describe your ideal sound or pick a one-tap preset for Gaming, Movies, or Music. The iFi GO blu Air offers XSpace to tune the soundstage. Pick knobs for direct control during listening, or PEQ and XSpace if you prefer presets and software tuning.
Check outputs and inputs before you buy
An amp only works with headphones and sources it can connect to. The Fosi Audio ZH1 offers 3.5mm, 6.35mm, and 4.4mm headphone outputs, with USB, optical, and coaxial inputs and RCA outputs for active speakers. The iFi GO blu Air offers 4.4mm and 3.5mm outputs over Bluetooth 5.2. The Schiit Gunnr runs from a single USB-C connection and adds a mic input. Match the outputs to your headphones and the inputs to your source before choosing.
Frequently asked questions
Do I need a headphone amp for 250 ohm headphones?
The beyerdynamic DT 990 Pro carries 250 ohm impedance, which is ideal for dedicated headphone amps and pro studio interfaces. An amp with enough output, such as the Fosi Audio ZH1 at 2300mW or the Schiit Gunnr at 2000mW RMS per channel, gives the headphones the power they need.
What is the difference between balanced and single-ended outputs?
Balanced outputs use separate signal paths for each channel, while single-ended outputs share a common ground. The Fosi Audio ZH1 offers 3.5mm, 6.35mm, and 4.4mm headphone outputs for single-ended or balanced listening, and the iFi GO blu Air offers a balanced 4.4mm output and an S-Balanced 3.5mm output.
Can a headphone amp improve soundstage?
An amp with soundstage controls can expand or contract the soundstage. The Schiit Gunnr has Width and Presence knobs for that purpose, the Fosi Audio ZH1 offers Smart PEQ with a wider soundstage option, and the iFi GO blu Air offers XSpace. Open-back headphones such as the beyerdynamic DT 990 Pro have a wide, natural soundstage.
Do I need a DAC with a headphone amp?
A DAC turns digital audio into an analog signal your headphones can play. The Fosi Audio ZH1, the Schiit Gunnr, and the iFi GO blu Air each include a built-in DAC. The beyerdynamic DT 990 Pro is a headphone, not an amp, so it still needs an amp or an interface to drive it.
