After 2008′s popular Image X5, which debuted at $100 less than the X10, Klipsch began expanding the affordable line of their inner
earphones. In 2009, the S2 and S4 join the Image line at the more reasonable prices of $49.99 and $79.99. When Klipsch designed the new earphones, they utilised brand new drivers which were made specifically for their sound signature. So, the S4 houses a special 8mm dynamic driver which packs dual neodymium magnets and the audio performance for which Klipsch is famous. Happily, Klipsch also introduced the iPhone-friendly S4i
which features a mic and remote and is priced at $99.99.
