The full-range 5 linear hybrid driver composed of quad dedicated Balanced Armature drivers to produce bass, mid, mid-high, high frequency and one specially tuned dynamic driver to produce sub bass.

Proprietary Acoustic Design

The Core Array Technology ™ aligns all acoustic components coaxially in the structure to increase drivers' efficiency, controls sound waves accurately and reduces distortion. The result is less sound degradation, finer detail and a spacious soundstage. The rigid composite acoustic structure of the X5i Titanium can also greatly reduce unwanted resonance to reproduce the purest sound possible.
