Headphones — Koss CL-2

The Koss CL-2 is a corded on-ear model in the clear series by Koss, a range of retro styled models with see-through housings that recall designs of the 1980s and 1990s. It is a simple, lightweight set meant for everyday use with phones, laptops and portable players.

Key specs that matter

Rated bandwidth is 100 Hz to 16,000 Hz. Impedance is 32 ohms and sensitivity is 88 dB SPL at 1 mW, which lets a phone output drive it without an external amplifier. The cord is 1.2 m long and ends in a 3.5 mm plug.

Engineering and use context

The see-through enclosures leave the drivers visible, and soft foam cushions press lightly against the ear. The short cord suits portable listening more than a home system.

Alternatives

Within the same clear series, the Koss CL/80 is a full-size over-ear model with larger leatherette cushions and a wider rated bandwidth.
