How we ranked these headphone amps
Every pick has at least 100 customer ratings on Amazon and 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: 4 channel stereo headphone amplifier
Count heads before you count channels
Channels and outputs are different counts here. The HA400 runs 4 channel output for up to 4 pairs of headphones, the HP4 runs 4 stereo headphone amps, and the ART runs 8 outputs across 4 channels. If 4 outputs cover your sessions, the HA400 or the HP4 fits. If you need more than 4 pairs at once, the ART gives you the extra outputs. Match the output count to the number of listeners in the room.
Decide how each listener sets volume
Personal volume control is the point of a distribution amp. The HA400 gives each channel a Phones Level control, so each listener sets a personal volume from the main mix. The HP4 gives headphone level control plus monitor control with a Monitor Mute button for the room feed. Pick the control layout that matches how your sessions run: per-channel level controls, or monitor control with a mute button.
Match jacks and power to your setup
Jacks decide which headphones plug in without adapters. The ART takes both 1/8 inch and 1/4 inch inputs and outputs, while the HA400 uses TRS connectors and the HP4 uses 6.35mm jacks. Power differs too: the HA400 includes a dedicated 12-Volt DC adapter, and the ART runs on corded electric power. Check the jack types on your headphones and the power you have at the desk before you buy.
