The Zoom ZHA-4 is designed for podcasters, musicians, and audio engineers who need a reliable, compact solution for multi-person monitoring in the field or the studio. Its primary benefit is the ability to split a single stereo source into four independent, powered headphone outputs, each with individual controls, though users should note it lacks balanced XLR inputs, requiring standard 1/8-inch connectivity.

Yes, provided your smartphone has a 1/8-inch headphone jack or you are using a compatible adapter.
No, the ZHA-4 is designed for standard stereo 1/8-inch (3.5mm) unbalanced connections.
Battery life varies based on headphone impedance and volume levels, but the unit is optimized for power efficiency during extended sessions.
While technically possible by sending an output to another input, it is not recommended as it may introduce noise and signal degradation.
No, the ZHA-4 is designed primarily for portable use and relies on battery power.
Verify the mute switch is not engaged and check that the volume knob is turned up.
Reduce the output volume from your primary audio source (mixer or recorder) to avoid overloading the amplifier input.
Replace the batteries immediately with fresh high-quality alkaline or rechargeable cells.
To set up the ZHA-4, connect your main stereo signal from your audio interface or recorder to the input jack using an 1/8-inch TRS cable. Insert fresh batteries into the compartment, then connect your headphones to any of the four output ports. For care, keep the unit away from extreme moisture or dust. When not in use, remove the batteries to prevent leakage. Wipe the exterior with a dry, lint-free cloth to maintain the finish.
