“Khan uses a ten millimeter dynamic driver for lows, four balanced armatures for mids and high mids, and a ten millimeter ceramic piezo electric super tweeter. The interesting thing about the piezo and the dynamic is, that they sit on top of each other. The low end DD is placed above the ceramic tweeter, and both share one stainless sound tube.
Noble is not very keen on disclosing too many technical details on the Khan, other than that it’s sensitive enough to be used with smartphones and digital audio players, but that really counts for almost all IEMs. Khan does pair very well with my gear, but due to its nature of design, it proves to be slightly harder to drive than other monitors in my inventory.”

“A problem with armature-based IEMs, such as my Ultimate Ears 18 Pros, is that their vibrating reeds start to run out of excursion with high levels of low-frequency tones, producing “doubling” (second-harmonic distortion). This was not the case with either the KSE1500 or KSE1200SYS earpieces, which played the low-frequency, 1/3-octave warble tones on my Editor’s Choice (CD, Stereophile STPH016-2) cleanly and with full weight down to 32Hz, provided the sleeves were making good seals with my ear canals. The combination of low-frequency clarity and weight in “Happiness Is Easy,” from Talk Talk’s The Colour of Spring (DSD64 file ripped from SACD, EMI 591452), made the sparse interjections from Danny Thompson’s double bass and Alan Gorrie’s electric bass sound suitably forceful. No, in terms of low-frequency weight, the in-ear Shures still couldn’t match my long-term headphone reference, Audeze’s LCD-Xes, driven in balanced mode by Ayre Acoustics’ EX-8 integrated amplifier. However, the over-ear LCD-Xes weigh my head down after the first couple of hours; the lightweight Shures remained comfortable throughout far longer listening sessions.”

“For the money, both earphones pack a punch. The Kickstarter sets the MS1 to 99$ (regular 149$) but would be a steal at full price. And the MS4 competes well against pricier earphones, both at its Kickstarter discount and its full price.Eventually, the cable prongs may wiggle themselves out of the earphones. Otherwise, both are well finished and well-built and should look good in years. Their cables should outlast the market.”

“The boosted low-end on the Model X bass-on mode does mean you will hear a bit more body to instrumental timbre. Lower pitched instrumental work, particularly guitar work with sound richer and more authoritative on this switch setting much like the custom Model X.
Vocals for me do not actually change their position or presence with either switch but due to the more elevated nature of the low end with the bass-on mode they will struggle for a bit more air and fall a bit further back in the mix. When there is less bass energy, however, vocal timbre does sound a little fuller and warmer than when the bass mode is off which I prefer at times, especially for female vocals.
Staging does change on the Bass-On mode compared to Bass-Off. I find the depth to improve on the Bass-On mode with relatively the same level of height and air compared to the Bass-Off mode. With the bass turned off the Model X sounds more linear, not quite as deep or forward sounding but the mids are a bit more open and spacious sounding as a result.”
