Beating out dynamic IEMs? How so? Some of multi-BA in-ears have good amounts of high treble, but in distortion performance, they are significantly worse than other dynamic in-ears (e.g. the RE400 and MDR-EX1000). The advantages of the balanced armature are in efficient sound output and size. I guess we can also count not needing a depressurization hole as a plus as well. Balanced armatures are old technology; they've been around since before the 1940s.
