It took eight years of stubborn engineering for the
headphone masters at Shure to shrink down the complexities of
electrostatic drivers and reduce them to something that could fit perfectly inside your ear canal.
We eluded to the wild world of
electrostatic drivers in the intro, but let's do a crash - course review for those who aren't yet intimate with the technology: Most in - ear
headphones use one of two driver technologies: dynamic drivers, which are essentially micro-sized versions of the speakers in your home, or balanced armature drivers, which are extremely tiny tubes (armatures) wrapped in a voice coil that vibrates when electrified, again, creating sound.
