Always Included

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 lightweight 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.

Universal Connectivity

Euclid's high sensitivity and low impedance make it an ideal companion to any high-resolution audio player. The gold-plated MMCX plug terminations ensure a secure and durable connection whether you're using the braided cable we've included or your custom design.

Precision-Milled Aluminum Body

Smoothly contoured with an elegant matte black finish, Euclid's lightweight and durable body is precision-milled from solid aluminum and capped with a layer of carbon fiber.
