The Koss SPARKPLUG model is a mid-grade, "budget" headphone set designed to imitate more expensive models and provide an exceptional listening experience at a cheaper price. The headphones are targeted for pure music audiophiles of all ages, and Koss claims the headset provides accurate acoustical reproduction and sound isolation. The SPARKPLUG headphones feature a dynamic element that sits just outside the ear, and a connected tubular ear-bud port structure designed to expand in order to fit snugly inside the ear canal and block out excessive ambient noise. The SPARKPLUG ear-bud cushions are made of soft hydrophillic, formed urethane, for a comfortable and custom ear fit. Additional SPARKPLUG features include extra ear cushion sets, a 4 foot tangle free cord with a white color that matches the design of most modern mp3 players, a gold plated mini stereo plug for maximum conductivity, and a Koss "No-Questions asked" lifetime warranty. The Koss SPARKPLUG ear-bud headphone set was released on May 2, 2006 and has an MSRP of $14.99, which is listed on the official Koss website.
