And there are literally hundreds of... Read More »


Obravo EAMT-2C IEM - Breathtaking Musicality, Transparency, and Engagement!


We review products across a relatively narrow band, a niche, if you will.

That so much transparency—detail, macro/micro-dynamics—and music lies within these small and, relatively, inexpensive IEMs is, no doubt, a wondrous discovery.
