Koss The Plug, Wired, 10 - 20000 Hz, Music, 7 g, Headphones, Black

Koss The Plug is a stereo earbud for the discriminating listener. It delivers accurate acoustical reproduction and unbelievable isolation typically found in more expensive, closed-style stereophones. The Plug features a dynamic element that is positioned just outside the ear and connected to a tubular port structure that is inserted on a soft expandable cushion into the ear canal. The soft foam cushion expands for a custom fit to improve isolation and enhance deep bass and treble clarity.

The Plug has special ear cushions made of hydrophilic, formed urethane, for a custom fit each and every time it is inserted into the listener's ear. The custom fit enhances isolation when you want to plug out ambient sounds that interfere with the listening experience. The Plug delivers the full sound of Koss. Combined with your favorite music and a portable sound system, it is the ultimate accessory on the go. A mute switch on the cord provides connection to the outside world without having to un-plug. Four extra ear cushions and a colorful vinyl carrying case are included.
