Audeze Euclid Review | 93 Data compared

The Audeze Euclid closed-back planar magnetic IEMs are lauded for exceptional technical performance, including immense detail retrieval, excellent microdynamics, and a wide, 3D soundstage, according to Head-Fi user reviews. They feature a robust, precision-milled aluminum build, comfortable fit, and strong, controlled bass, with high transparency that responds well to EQ. Conversely, the stock, often-dark treble tuning can feel recessed for some, while a forward, nasal-sounding upper midrange can lead to piercing vocals. Further criticisms focus on the large, finicky shell design, thin stock cable, and susceptibility to scratches on the carbon fiber faceplates, often making EQ necessary to unlock the driver’s full potential.

The MMORPG.com review of the Audeze Euclid praises these IEMs for their superb build quality, featuring a precision-milled aluminum chassis and an 18mm planar magnetic driver. The device delivers excellent tonal balance, exceptional detail retrieval, and a wide, airy soundstage, with a fast, dynamic performance that emphasizes high-quality, articulate bass. MMORPG.com Conversely, the review notes that the bulky, unvented, egg-shaped shells can make achieving a proper fit difficult, often causing ear fatigue during long listening sessions. Furthermore, while refined, the bass may be perceived as lacking impact by some, and the stock 3.5mm cable is considered underwhelming for a high-end product. YouTube ·

The Audeze Euclid is a groundbreaking, closed-back in-ear monitor (IEM) that utilizes a singular 18mm planar magnetic driver without crossovers, packing proprietary technologies like Fazor waveguides and Fluxor magnets into a lightweight, precision-milled aluminum housing with carbon fiber faceplates. On the positive side, it delivers an exceptionally wide, cohesive sound stage that rivals full-sized, open-back planar headphones, alongside effortless neutrality and immaculate micro-detail in the mid-to-high frequency ranges. It features high-quality accessories like SpinFit eartips and a Pelican case, accommodates multi-hour usage comfortably via a self-supporting geometric design, and uses a highly versatile, tangle-resistant stock MMCX cable. However, the Euclid suffers from a noticeably minimal bass response that largely lacks the sub-200Hz micro-detail and deep texture typically associated with Audeze's full-sized gear. Its single-driver configuration struggles with complex, modern genres like heavy metal, hip hop, and pop, causing the upper mid-range to dissolve into a mesh of sound during busy tracks. Furthermore, the upper-frequency range can occasionally sound sibilant and scratchy, while male vocalists lack the necessary lower-midrange depth to accurately reproduce deeper, huskier voices.

The PCMag review of the Audeze Euclid positions these $1,299 in-ear monitors as a high-end audiophile tool, praising their 18mm planar magnetic drivers for delivering superb, accurate, and dynamic audio with exceptional midrange and treble clarity. The earphones are noted for their secure, comfortable fit and comprehensive accessory package, making them ideal for critical listening, jazz, and orchestral music. However, PCMag highlights that the steep price tag does not include a custom-molded design and the sound signature is not tuned for mainstream, bass-heavy preferences. Additionally, the drivers may distort when pushing extreme sub-bass levels on certain modern tracks.
