Planar Magnetic. Closed-Back. In-ear. Precision-milled Aluminum.

Our new Euclid combines all of these features to deliver superior detail retrieval and sonic accuracy with a soundstage and dynamic range so robust you'll forget you're listening to a closed-back in-ear. The extra-large 18mm single planar magnetic driver has no crossovers, resulting in superior cohesion across the entire frequency spectrum. Euclid is engineered for an incredible 105 dB/mW efficiency and a max SPL well over 120dB*, giving it the highest dynamic range of any in-ear in its category. The smoothly contoured light weight design incorporates precision-milled aluminum and carbon fiber for a look that combines elegance and comfort.

Patented 18mm Planar Magnetic Driver Technology

Euclid's 18mm planar magnetic drivers incorporate Audeze's patented Fazor™ waveguides to eliminate the phasing and distortion typical of most closed-back dynamic in-ears. The efficient single driver design also includes our patented Fluxor™ magnets and Uniforce™ voice coils to further reduce distortion, improve sensitivity, and create superior coherency across the entire frequency spectrum.

 

Ergonomic Design

Euclid's small 5mm ear port, contoured design, and light-weight construction work together to create an ergonomic fit suitable to most inner-ear shapes. The braided cable is routed behind the ear for enhanced stability, eliminating the need for ear hooks and improving comfort over extended listening sessions.
