Loyal readers of my reviews would know that these are not aspects that I often write about, much less dedicate an entire section for, but I feel like I should make an exception in this case.

The shells of Gaudio’s IEMs are, to put it simply, the best universals shells I’ve come across. I truly believe that if every single IEM in the industry was built like the Nair and Clariden, I wouldn’t even mind. Now this may come off as hyperbole or straight shiling, so allow me to justify.

In terms of build, the shell is segmented into three parts: the main aluminium frame, the aluminium faceplate and the stainless steel nozzle. This means that the shells have two seams that join the three parts together, and if I were to really nitpick I would say that I wished that the faceplate seam was a little more discreet and flush, since I could feel the inconsistent finishing when I run my fingers over them (especially around the edges). But overall, the shell materials are dense, sturdy and have considerable (but not overly so) heft to their overall weight.

Not only its build, but the fit is also one of the main highlights of Gaudio IEMs. The overall shape of the shells is undeniably pseudo-custom, which is not a particularly special attribute in today’s IEM market. What makes Gaudio IEMs stand out is the well thought-out nozzle barrel extension that really helps with maintaining a consistently deep insertion depth and thus, a secure fit. Couple that with the nicely contoured concha area, and what you get is easily the best fitting metal-shell IEM out there.

Basically, what you get is the build quality of Campfire Audio IEMs in combination with the fit of great pseudo-custom IEMs like the In-Ear ProPhile-8. Without taking into consideration its sound, I think Gaudio IEMs have at least earned the right to be considered “luxury” and/or “premium”.

That said, these are IEMs we’re talking about. So speaking about sound…
