Koss KEB9i In-ear Headphones, Blue

The Koss KEB9i are wired in-ear headphones that connect to devices using a standard 3.5 mm audio plug. They are designed with an angled port to facilitate a more direct fit within the ear canal. The audio specifications include a frequency response range of 18 Hz to 20,000 Hz, an impedance of 16 ohms, and a sensitivity of 110 dB. To help users achieve a proper seal and stable fit, the package includes multiple sizes of ear cushions.

For everyday functionality, the KEB9i incorporates an in-line microphone, enabling hands-free calls. The 1.2-meter cable also houses a single-button remote for managing calls and media playback. As these are wired earbuds, they do not require batteries or charging, providing continuous audio as long as they are plugged into a source. The simple, lightweight construction is suited for listening while commuting or at a desk.
