Our take on the Koss Ke5k 3.5mm Connector Earbud Earphone

The Koss KE5K is a wired in-ear earbud with a 3.5 mm plug, a 4 ft cable and an inline volume and play/pause control. It uses 16-ohm dynamic drivers with a 60 Hz to 20 kHz range and a closed acoustic seal that blocks some surrounding noise. It suits people who want a simple plug-in pair for a phone, laptop or player and do not want to charge anything. Against Bluetooth earbuds it gives up wireless freedom but needs no battery and no pairing.
