Product Details from the Brand

↓ Details provided by Empire Ears

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.

In order to increase the usability and lifespan of our cabling we have partnered with Effect Audio to bring to market an evolution of their well loved cable, the Ares II, known as the Alpha IV (A4).

Rocking new y-splits and over-molded 2-pin barrels, this new cable delivers the same high performance in a package truly built to last.
