In this article we look at the Audeze Euclid IEM, selling for $1.299 USD.
Disclaimer: The Audeze Euclid IEM was sent to us by Audeze directly, in exchange for our honest review. Audeze is not related to Headfonia in any way.
If you’ve been following the personal audio world for the last 10 years, then Audeze will ring many bells. The California, USA based company completely changed and upped the headphone game to new levels. Bio from the Audeze site:
Audeze’s origins go back to 2008 when founders Sankar Thiagasamudram and Alexander Rosson met engineer Pete Uka who developed specialized flexible circuit materials for NASA. They quickly realized the material might be perfect for headphones. That’s when Dragoslav Colich, who has 30+ years’ experience in designing planar drivers, joined the team as CTO to create the LCD-1 headphone.
We’ve reviewed almost all of the Audeze products here on Headfonia, the latest one being the LCD-i4, Mobius, LCD-MX4 the LCD-2 Classic, the LCD-1 and the Penrose headphone.
Planar Magnetic Technology
As the Euclid is a planar magnetic technology IEM, we’re giving a short summary of the tech for those not familiar with it.
Audeze feature proprietary planar magnetic designs with extremely thin-film driver materials and powerful custom magnets. Planars overcome many limitations inherent in typical cone drivers; our lightweight diaphragms are, for example, faster and more responsive than heavier moving-coil or dome drivers. Planar magnetic diaphragm also have a voice-coil circuit spread across the diaphragm surface. The diaphragm’s voice-coil circuit interacts with the magnetic field to produce an electromagnetic force that moves the diaphragm back and forth creating the sound you hear when energized by an audio signal.

The Euclid is Audeze’s first planar magnetic IEM which has a closed back design. The miniaturized 18mm single planar magnetic driver has no crossovers and that, according to Audeze, is resulting in superior cohesion across the entire frequency spectrum. The Euclid is engineered for an incredible 105 dB/mW efficiency and a max SPL well over 120dB, which is pretty impressive.
You can find out all about the Audeze Euclid on its dedicated webpage here: https://www.audeze.com/products/euclid
The 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 their patented Fluxor™ magnets and Uniforce™ voice coils to further reduce distortion, improve sensitivity, and create superior coherency across the entire frequency spectrum.

Box & Accessories
For this kind of money you expect a high quality package and a full set of accessories. Audeze here doesn’t disappoint, though the packaging itself is not very special.
The Euclid however comes with a very comprehensive set of accessories, which make you forget all about the simple box and foam interior. You get all of the following:
- A user guide & Driver download card
- A certificate of authenticity
- A lovely soft carrying pouch
- A pelican hard case
- A shirt clip
- A cleaning tool
- 1 set of Spinfit tips (S/M/L)
- 1 set of Foam tips (S/M/L)
- 1 set of normal silicone tips (S/M/L)
That’s a very complete package where only a cleaning cloth is missing. Check it out for yourself here:
Design & Housing
The Audeze Euclid has a precision-milled aluminum body and each monitor is smoothly contoured with an elegant matte black finish. The face plate shows the Audeze logo and that sits on a layer of carbon fiber, making it look really nice. Audeze describes it as a look that doesn’t sacrifice elegance for comfort.
The ear pieces are not the biggest but they’re not small either, so the units do stick out of your ears quite a bit, but it’s still acceptable. This of course strongly depends on the shape of your ears, but listeners with smaller ears will for sure notice this.
Design-wise I like these IEMs: smooth edges, discrete L/R markings, a pretty face plate and eye for detail with a golden ring in the middle of the shell. The nozzle size is reasonably normal. The length is actually short, but because of the typical design of the shell, it looks quite long. The width of the nozzle is quite large, so this should be taken into account if you have small canals, especially of you want to use foam tips.
Talking about the nozzles, you’ll find that there is no mesh grill covering it, so make sure you keep your ears, and the nozzle clean. In fact when you look inside the nozzle you’ll see that there is some kind of foam, or fabric stuffed inside. Special.
All-in-all a pretty design and a great looking IEM.
