About Koss

Koss Plug is a Stereo Earbud. The Plug earbud is the first of its kind. 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 features special ear cushions made of hydrophillic, 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 has a frequency response performance of 10-20,000 Hz and full Sound of Koss. Combined with your favorite music and a portable sound system, it is the ultimate accessory on the go.

Sounds tinny to me


I was going to use them for listening to my computer mp3's but really my cheap headphones with the foam pad falling off sounded much better both hi and low. They're good for listening to Netflix or people talking but get some other headphones for music. They are extremely comfortable to wear. You forget you have them.
