Koss Pathfinder 178378 In-Ear Earbuds with Volume Control accessory

Koss Pathfinder In-Ear Earbuds

The Koss Pathfinder 178378 are wired in-ear earbuds finished in black with a white cord. A dynamic element sits outside the ear and connects to a tubular port structure that feeds sound into the canal. Slow-memory ear cushions made of hydrophilic formed urethane expand for a custom fit that improves isolation and enhances deep bass and treble clarity. An inline volume control is built into the cable for convenient level adjustment.

Suited for portable listening with a custom fit

These earbuds suit listeners who want a secure, expanding foam seal that blocks ambient noise and boosts bass and treble detail. The four-foot cord and inline volume control make them practical for use with portable players at a desk or on the move. Buyers who need wireless connectivity, an integrated microphone for calls, or a shorter cable for highly mobile use should look at other models.

Frequency response 10 Hz to 20 kHz

The specified frequency response of 10 Hz to 20 kHz defines the audible bandwidth these earbuds are designed to reproduce. This range covers the full span of human hearing and indicates the capability for deep bass extension and clear treble detail. Match this specification to your source material and listening preferences to confirm the Pathfinder meets your tonal requirements.
