Not directly to most interfaces, which have one headphone socket. A passive splitter works at low volume and shares the power between both pairs; a headphone amplifier is the proper answer for two people.
The simple version
A Y-splitter. Cheap, immediate, and it halves the available drive.
The proper version
A small headphone amplifier fed from the interface’s output, with a level control per pair. That is how rehearsal rooms and podcast setups do it.
What not to do
Chain splitters. Each one divides the drive again, and the result is quiet and noisy.
Check your own manual before you plug anything in. Voltage, polarity and current draw differ from model to model, and the manufacturer’s figures take precedence over anything written here. A supply of the wrong polarity can damage a pedal in seconds, phantom power is safe for most microphones but not for every one, and the required voltage is printed next to the socket or stated in the manual — not inferred from a connector that happens to fit.
The questions players ask
Why does a splitter sound quiet?
The output has to drive two loads instead of one, so each pair receives less. With low-impedance headphones it is often acceptable.
What if I need four?
A dedicated headphone amplifier with individual level controls. That is also what lets two people set their own volume.
