ESR MKII Custom IEMs

The Empire Studio Reference - ESR - has invariably found its way into the hands of recording and mixing engineers the world over. Endorsed by professionals from every corner of the globe, the ESR was the detail-king of the Empire Ears line-up, and now the MKII version's inclusion of a dual EST array raises the bar even higher.

Presenting with a much larger soundstage and absolutely ludicrous resolution, the ESR MKII's exceptionally linear sound signature gives the listener a pristine image of every element in the music - every detail is highlighted and positioned with extreme accuracy across the frequency spectrum.
Delivering with a mathematical authority more reminiscent of a scientific instrument than a personal listening device, the ESR MKII has set a new standard for those seeking resolution and detail. The ESR MKII comes dressed to deliver surgical precision with its Brushed Silver faceplate.
