The Koss KEB9i are wired in-ear headphones that connect to audio sources via a standard 3.5 mm plug at the end of a 1.2-meter cable. This configuration ensures broad compatibility with a wide range of devices, from smartphones to personal computers. The internal drivers provide a frequency response of 18 Hz to 20,000 Hz. With an impedance of 16 ohms and a sensitivity of 110 dB, they are engineered for efficient performance with standard consumer electronics without requiring external amplification. The earbuds feature an angled port design to aid fit, and the package includes extra ear cushions to help achieve a secure seal.
Functionality is extended with an in-line microphone for voice calls and a single-button remote for managing media playback and answering calls. The binaural, in-ear design provides passive noise isolation by physically blocking the ear canal. The entire assembly is lightweight, weighing 18 grams, which contributes to comfort during extended listening sessions. This makes them a practical option for daily commuting and general media consumption where a simple, reliable wired connection is preferred.
