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

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.

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 own custom design.

Precision-Milled Aluminum Body

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

The Perfect Fit

To give you the best fit with the best comfort, Euclid comes
with 2 different styles of silicone and foam eartips including Comply models.

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.
