Noble Kaiser K10 – Custom In-Ear Monitor

A while back, after spending a little time with the Shure SE846, I decided to part with my Unique Melody Miracle custom IEMs. In time I came to regret not having a custom-molded IEM in my collection so I began considering a replacement. Somewhere around that time I also had the chance to try the Noble PR universal IEM which, although not to my sonic tastes, showed a degree of tuning expertise that instantly intrigued me – the PR managed to deliver a crisp, super-clean, treble-focussed sound without harshness or sibilance – a huge feat in my experience. With Noble firmly on my radar and a clear sense of the type of sonic presentation I wanted, I started to consider their other offerings and decided eventually on the Kaiser 10 CIEM.

Before I get into the normal format, I wanted to say that the K10 is the first earphone / headphone that has ever left me wanting more… I’ll let you read on to see what that really means…

Overview

Noble hardcaseIn the world of personal audio, the ultimate sound experience generally comes from custom molded in-ear monitors (CIEMs). In recent times, top of the line (TOTL) CIEMs have gone from 3-6 balanced armatures per side to 10 and even 12 BAs per side. The Kaiser 10 is an example of a 10 driver CIEM and has 10 individual drivers in each ear-piece – a pretty awesome piece of spatial design, but also a challenge of epic proportions when it comes to ensuring that all of those drivers are delivering their frequencies in time with and in support of the other drivers in each ear piece.

One of the largest challenges of any multi-driver setup (including speakers) is to have each driver deliver its optimum frequencies without interfering with the frequencies coming from the other drivers. A speaker manufacturer faces challenges with 2-3 drivers so imagine what happens when you get 10!! Add to that the challenge of placing the drivers at slightly different distances from the sound outlets and the possible timing / phase challenges this presents and getting everything right to the level expected of a flagship CIEM becomes a daunting prospect.

Noble PR IEM

I find myself in the enviable position of having way too much gear to review at the moment thanks to a couple of purchases (Mr Speakers Mad Dogs and Shure SE846s) in addition to being included on some product tours for IEMs such as the Audiofly AF180s and these Noble PRs. I also have an upcoming review of the very interesting FIDUE A83s. For that reason I’m going to keep this review brief in words, but hopefully heavy on meaningful content. So here we go…

Overview

The Noble PR is one of 2 IEM models from Noble that include a switch on the IEM body that allows you to change the signature of the IEM on the fly. In the case of the PR, the options are a “Pure” sound (P) or a “Reference” sound (R). This is a first (as far as I know) because it is essentially two IEMs in one. For more detail, please take a look at the Noble website and while you’re there, do your eyes a favour and take a look at the “Wizard” range of universals – they are strikingly beautiful one-off, unique IEM designs that are incredibly affordable as a great sounding piece of artwork!

The only other specs I want to provide here are that these IEMs have two distinct impedances – approximately 240 ohm or 30 ohm depending on the mode.

By the way, before I continue I’d like to say thank you to Noble and Head-Fi’er, d marc0, for arranging this tour!! It’s a great initiative in the community to get people experiencing and talking about gear they might not otherwise try. Playing with the PRs has certainly got me very interested in Noble’s other products thanks to the great build quality and execution of the PR.
