Headphones — Koss CL/80

The Koss CL/80 is a full-size cabled over-ear set in the Koss clear lineup, pairing a vintage inspired look with a clear shell. It is the over-ear option in a range that otherwise leans on smaller on-ear sets.

Key specs that matter

Its stated range runs from 16 Hz to 22,000 Hz. Impedance is 60 ohms and sensitivity is 101 dB SPL at 1 kHz and 1 mW. Connection is through a 1.8 m cord with a 3.5 mm stereo plug.

Engineering and use context

Extra large leatherette ear cushions surround the ear for isolation, and the headband is fully adjustable for fit. The clear housings leave the internal parts on show.

Pairing

The high sensitivity lets phones, computers and portable players drive the CL/80 directly.
