What the AI looks for in Headphone Amps

Power at your headphone's impedance
Compare output power at the impedance of your headphones, not the headline figure, which is usually given at a low impedance. High-impedance and planar headphones need far more voltage or current than earbuds.
Output impedance
Keep output impedance below one-eighth of the headphone's impedance. A high output impedance changes the frequency response of low-impedance headphones and IEMs.
Noise floor and gain steps
For IEMs, choose a low gain setting and confirm silence with no music playing. Sensitive IEMs reveal hiss and channel imbalance at low volume.
DAC included or not
Buy a combo DAC/amp for a computer or phone source. Buy an amp-only unit if you already have a DAC with line out. Paying twice for a DAC adds cost and clutter without improving the sound.
Balanced output
4.4mm or 4-pin XLR outputs only help if your headphone cable is or can be made balanced. Balanced outputs often give more power but are useless with a single-ended cable.

Brands that matter

  • FiiO: Broad range covering portable Bluetooth units, dongles and desktop DAC/amps.
  • Topping: Measurement-focused desktop amps and DACs with low noise.
  • Schiit: US-made desktop amps such as the Magni line, popular as value amp-only options.
  • JDS Labs: Well-measured desktop amps such as the Atom line.
  • Moondrop: Compact USB dongles aimed at IEM users.
  • iFi: Portable and desktop DAC/amps with extra features like bass and soundstage switches.

What to avoid

  • Buying an amp for efficient earbuds or headphones that already reach comfortable volume from your source
  • Cheap tube 'hybrid' amps with high output impedance for low-impedance headphones
  • Stacking an amp after a phone's headphone jack instead of using a USB DAC

Questions

Do I need an amp for my headphones?

Usually only if they are high-impedance, low-sensitivity or planar, or if your source can't reach comfortable volume without distortion.

DAC or amp, which matters more?

For hard-to-drive headphones the amp matters more. For quiet, hiss-free playback on a computer, a clean USB DAC/amp combo is enough.
