Audeze introduces Euclid, its first closed-back in-ear headphone


Audeze is a California based premium technology company that has been engineering some of the world’s best audio devices. We’ve reviewed several of its gaming headphone offerings, which you can find here. Now, the company has announced its new closed-back planar magnetic in-ear headphones.

Euclid is the first closed-back in-ear headphone from Audeze and is priced at US$1299. Euclid features custom built 18mm Audeze planar magnetic drivers, MMCX cable terminations, and ergonomically designed precision-milled aluminum housing.

The company targets its products for audiophiles, but these IEMs should also work brilliantly for on-stage musicians and audio engineers. While US$1299 is a lot for a pair of headphones, these are on a slightly different level than what we’re used to. Here are some of the features and specifications of the Audeze Euclid and a look inside the Euclid.
