Koss Noise Reduction Headphone 180125

Keep critical audio intelligible in noisy environments. Koss 180125 is a passive noise reduction stereophone designed to isolate the listener from ambient sound without relying on batteries or active electronics. That makes it a practical fit for racing scanners, metal detectors, and other field applications where dependable monitoring matters more than extra features. The earcup volume control allows quick level adjustment without reaching for a separate device, while the stereo/mono switch adds flexibility when source material or operating conditions change. A single-entry 8-foot coiled cord gives you reach without excessive slack, helping the headphone stay manageable during movement and equipment handling. Compared with basic consumer headphones, this model is built around utility: isolation, control, and field-ready cabling. For users who need to hear the signal, not the room, Koss 180125 delivers a focused listening tool with the kind of practical detail that supports real work.
