Audeze has announced Euclid, their first closed-back planar magnetic in-ear monitor.

Engineered with Audeze’s patented technology inside a precision-milled aluminium housing, Euclid claims to deliver a soundstage and dynamic range “so robust you’ll forget you’re listening to a closed-back in-ear”.

Audeze Euclid Planar Magnetic IEMs

The miniaturised 18mm single planar magnetic driver has no crossovers, resulting in cohesion across the entire frequency spectrum.  Euclid has a 105 dB/mW efficiency and a max SPL well over 120dB.

Audeze Euclid Planar Magnetic IEM have an ergonomic design

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. Euclid comes with three different styles of silicone and foam eartips including SpinFit and Comply models.
