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 metal
Match the input to your mixer or player
Start with the jack your source uses. The STABCL takes XLR or 6.35mm TRS input, so it plugs straight into a mixer or audio interface. The PROZOR takes a 3.5mm input, so it suits MP3 players, smartphones and laptops with a 3.5mm output. The STABCL 8-channel and the Horse take 1/4 inch and 1/8 inch plugs. Pick the amp whose input matches the source you already own, and check the output jack fits your headphones.
Count the headphones you need to drive
One listener needs one output, and a group needs one output per listener. The STABCL in-ear amp and the PROZOR each serve one pair of headphones through a 3.5mm output. The Horse serves 4 channels with a separate volume control on each one. The STABCL 8-channel serves 8 channels, each with its own volume control. Count listeners first, then pick the channel count that covers them.
Check battery life and power before you buy
Power decides where an amp works. The STABCL in-ear amp runs on a built-in 500mAh battery for more than 30 hours after 15 minutes of charging. The PROZOR runs on a 1500mAh battery for 8-10 hours and charges through a Type-C port. The STABCL 8-channel runs from an included 12V AC adapter, and the Horse runs on DC 12V. If your sessions run past the battery hours, pick the amp with the included 12V AC adapter.
