Bought Sony MDR-EX38iP headphones to replace Apple MA850G/A In-Ear Headphones with Remote and Mic, complementing Klipsch S2M. Sony has deeper bass and less sparkle than Apple. Now surprised how unnatural Apple headphones sound. Klipsch has more detail in both bass and treble, but wanted cheaper headphones with remote while bicycling. Sony MDR-EX38iP controls work on iPod 3G, Klipsch S2M controls don’t.
