The Bravado MKII embodies Empire Ears' relentless quest to push the limits of design and performance to a new extreme. With bolder styling, more technology and performance than ever before the Bravado MKII takes its class-obliterating heritage to unprecedented heights. UPDATED DESIGN The Bravado MKII is the next generation of the Bravado and is the sequel to one of our best selling IEMs. At its core is a substantially upgraded 4 driver tribrid configuration designed to exude the same u-shaped fighting spirit as its predecessor while addressing the growing need for even more dynamic range, detail retrieval and soundstage. All of this is made possible with the most advanced IEM technology currently available: a next generation W9+ subwoofer, a proprietary balanced armature driver and dual electrostatics divided 6-ways via a reengineered synX crossover network backed by EIVEC and ARC resonance mitigation technology.
