01 / Impedance & source

Heuristic picker: ohm “comfort” bands are illustrative. Real drive also depends on sensitivity, gain, and output power.

Runs locally on your device.

02 / Suggested tier

Sensitivity, balanced outputs, and phone USB-C power limits also matter.

Hard-to-drive cans usually need more voltage — desktop or powered sticks fit better.
