Detail 01
150 ohm input impedance
A low input load. Feed it from a driven output, not straight off a passive instrument pickup.

Independent shopping perspective
A single-purpose box that taps an existing signal off to headphones. For engineers and players who need a monitoring feed without rewiring the whole chain.

What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
A low input load. Feed it from a driven output, not straight off a passive instrument pickup.
Detail 02
It derives a listening feed from a signal already present rather than generating its own drive stage.
Detail 03
Sits in the middle of common headphone impedances. Low-impedance earbuds and 250-600 ohm studio cans behave differently here.
Detail 04
You are paying for a clean monitoring point. Budget separately for anything that shapes the sound.
Detail 05
Disappears in a dark rack or under a desk. Label it if you run several small utility boxes together.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
The 150 ohm input impedance sets the load it presents, not its output power. High-impedance cans such as 250 or 600 ohm models will play quieter than low-impedance pairs.
It is a monitoring tap, not a processor. There are no EQ, gain, or effects controls, so anything you hear comes from the signal you feed it.
Plan on one listening point per unit. For multiple performers on separate feeds, a dedicated multi-output headphone distribution amp is the better fit.
Yes, plan on patch cables plus your own headphones. Match the connector type and length to where the box sits in your setup.
