Koss KEB9i In-ear Headphones, Gray

The Koss KEB9i are wired in-ear headphones that connect to audio sources via a standard 3.5 mm plug. The audio hardware operates within a frequency response range of 18 Hz to 20,000 Hz, with a sensitivity of 110 dB and an impedance of 16 ohms. These earbuds feature an angled port design, which directs the sound into the ear canal. This structure is intended to create a secure fit and provide a degree of passive noise isolation from ambient sounds.

For everyday functionality, the KEB9i includes an inline microphone for making calls. A single-button remote is integrated into the 1.2-meter cable, allowing for management of media playback and call handling without directly using the connected device. The total weight of the product is 40 grams, contributing to its portability for daily transport and use. To accommodate different ear sizes, the package comes with additional sets of ear tips, enabling users to find a suitable fit.
