14 Balanced Armature Drivers

14 Balanced Armatures

Zeus-XR boasts 14 proprietary balanced armature drivers, each individually tuned via our advanced crossover network in order to achieve maximum coherence and resolution. Each and every driver at Empire Ears is subject to strict quality control tests before we apply a patent-pending nano magnetic coating. This conformal coating not only resists moisture and other harmful contaminants but also optimizes performance by shielding each driver’s magnetic field to eliminate all interference.

Using only the most exceptional components the Zeus-XR’s internals are individually wired and insulated with 7-strand, sapphire and gold, silver-plated copper Litz wires to eliminate acoustic feedback and further soldered with robust, ultra pure quad-eutectic for maximum conduction.

Dual Crossover System

8 Way Crossover

The Zeus-XR features a state-of-the-art, industry leading dual crossover system that allows the user to switch between both the Zeus XIV and Zeus R instantaneously at the flick of a switch on the faceplate. The up position activates the Zeus R’s 14 driver, 8-way crossover network and the down position activates the Zeus XIV’s 14 driver, 7-way crossover network. Unlike other in-ear monitor companies, Empire Ears does not use filters or dampers to manipulate the frequency curve. That method of tuning forces the drivers to operate outside of its intended frequency range, often duplicating too many of the same frequencies from numerous drivers. This means you’ll have to turn the volume up to hear what you want.

Our method of tuning allows the drivers to behave naturally as our crossover network is engineered to assign the proper frequencies and levels to the corresponding transducer. The end result is a crystal clear, full range frequency response that can be heard even at low volumes.

Quad Bore Design

Quad Bore Design

The Zeus-XR features 4 precision ported sound bores with a designated bore for highs, mids, mid-highs, and lows. Each bore is engineered and hand ported in-house to our exacting clearances in order to achieve optimum phase alignment, consistent performance, and the truest sound possible every time.



Bespoke Handcrafted Cables

Ares II Cable

Every Zeus-XR in-ear monitor includes a bespoke, handcrafted Ares II cable by Effect Audio. The Ares II boasts a proprietary blend of 26 AWG UPOCC Litz copper with ultra-flexible insulation for maximum signal speed transmission, performance, and ergonomics. Each cable is terminated in an ultra durable 3.5mm, 24k gold plated right angle plug. 

Effect Audio’s extensive engineering and manufacturing background gives them the edge over all other cables. After extensive testing with numerous other cable manufacturers we’re proud to announce our official partnership with Effect Audio to bring you the finest cables in the industry and to ultimately defeat the weak link in IEMs.

 Proudly Handcrafted In The USA

Empire Ears has long prided itself for home-grown craftsmanship, with artisans donning lab coats and honing years of OEM factory experience before being entrusted to handle the Empire lineage. While several of our competitors have taken their manufacturing overseas we’ve remained true to our USA roots to not only provide jobs to our local community but to ensure that quality is never compromised.

Every Empire Ears in-ear monitor is proudly designed, engineered, and manufactured in Norcross, Georgia USA. The process of building each Empire in-ear monitor is unique, a seamless collaboration of technology and human touch. Engineers and technicians guide each IEM along its journey to completion, a process of 22 stations for a total of 14 hands-on hours. It all begins with your unique ear mold.
