Just what you'd expect from Polk, and more. Like Dynamic Balance driver tuning on a micro scale, using material technology to tune out resonances that are a common complaint of headphone performance. Plus, fine-tuned diaphram geometry, a detail usually missed by headphone makers, that ensures a more dynamic, expansive headphone listening experience. Is this magic? Is this technology? It's a little bit of both, and it looks and sounds simply amazing.
