Could MEMS be the next big leap in headphone technology?

If you have a pair of in-ear headphones, there’s a good chance they are using a technology that’s several decades old. Despite attempts to introduce different, exotic-sounding systems like planar magnetic, electrostatic and even bone conduction, most IEMs or in-ear headphones still use either balanced armature or dynamic drivers. But there’s another contender, promising high fidelity, low power consumption and a tiny physical footprint. The twist is, it’s a technology that’s been in your pocket for the last ten years already.
