Audeze Euclid

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 miniaturized 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 size category. The smoothly contoured light weight design incorporates precision-milled aluminum and carbon fiber for a look that doesn't sacrifice elegance for comfort.
