Sescom Inline Stereo Headphone Level Control with TRS Connectors (3.5mm)

This Sescom Inline Stereo Headphone Level Control with TRS Connectors features 3.5mm jacks for input and output. Supporting a stereo signal, this audio volume control affects both the left and right audio signal using a single knob. This passive unit requires no power, nor does it work with audio signals that have phantom power. Small enough to take with you anywhere, keep this unit handy for adjusting the volume of your headphones when working with a recorder or playback unit that does not allow you to adjust the headphone volume.
