The SPARKPLUG with New Improved Cushions
The SparkPlug 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. Now with improved
slow memory ear cushion made of hydrophillic, formed urethane, you are
guaranteed a custom fit every time.
Ths SparkPlug also featues a white cord to compliment many mp3 players. The fit
enhances isolation when you want to plug out ambient sounds that interfere with
the listening experience. The SparkPlug has a frequency response performance of
10Hz-20,000Hz and full Sound of Koss. Combined with your favorite music and a
portable sound system, it is the ultimate accessory on the go.
