Headphones — Koss CL-5i

The Koss CL-5i is a cabled on-ear set that puts a cable microphone with remote buttons onto the retro styled see-through design of the Koss clear series. It is meant for tablets, smartphones, gaming devices and computers with a standard 3.5 mm headphone jack.

Key specs that matter

Response extends from 60 Hz to 20,000 Hz. Impedance is 32 ohms and sensitivity is 94 dB SPL at 1 kHz and 1 mW, so portable sources can drive it without a separate amplifier.

Engineering and use context

These cable controls manage calls and music playback, which makes the CL-5i suitable for calls and voice chat as well as listening. Plush leatherette cushions and an adjustable headband set the fit, and the see-through housings keep the drivers visible.

Alternatives

For a full-size over-ear design from the same clear range, Koss makes the CL/80 with extra large leatherette cushions.
