High-end in-ear headphones like Roxanne use " balanced armature" drivers, which are much smaller than other types of headphone drivers, so the designers can squeeze more drivers into each earpiece. For example, the Jerry Harvey Roxanne headphone has a total of 12 drivers per ear piece (four bass, four midrange, four tweeters). Jerry Harvey Audio JH-13 has 6 balanced-armature driversĪlmost all full-size headphones have just one driver per earpiece, but some high-end in-ear headphones have more.
