Наушники — Koss KEB9i

The Koss KEB9i is an entry-level wired in-ear headphone with 9 mm drivers and an angled port shaped to follow the natural line of the ear canal. S, M and L silicone eartips are included so the fit and noise isolation can be adjusted to the listener.

Key specs that matter

Koss specifies 18 Hz to 20 kHz. With 16 ohm impedance and 110 dB sensitivity it runs directly from a smartphone. A 1.2 m cable finishes in a standard 3.5 mm plug.

Engineering and use context

Calls are taken hands-free via the in-line remote and its microphone. Finishes include black, grey, white and pink, and the model is backed by the Koss limited lifetime warranty.
