An Excellent Neutrally-Tuned 4-Driver Custom IEM

Posted

Pros: Flat tuning with no dips in the frequency response makes this perfect for people who want a neutral sounding CIEM; Clarity is very good.

Cons: If you don't want a flat tuning? Those who travel may wish for extra bass to balance train/plane engine roar.

Synopsis: The Noble Audio 4C is a custom-fit in-ear monitor (ciem) characterized by a flat tuning with no peaks or dips from the lower bass to the lower treble range. This upgraded tuning eliminates the dip in frequency response found in the older model. The bass, while not boosted at all, has excellent extension , the mids are clear and the treble is flat until a lift in the upper range which adds a sense of clarity and air to the sound. The tuning is excellent for acoustic, classical, folk, jazz, and rock genres and generally for audiophiles looking for a flat, accurate sound. Those who prefer bass-heavy earphones and music genres as well as those who listen primarily while travelling...

Simply Outstanding

Posted

Pros: Balanced signature that works with many music genres; bass, midrange and treble are all excellent

Cons: No real cons (this is one of the pros), although people should read the review to see if the sound signature matches their own needs.

Synopsis: The Noble Audio Kaiser 10 is at the summit of custom in-ear-monitors representing the flagship of new designs from Dr. John Moulton. The Kaiser 10’s 10 drivers have been brought together seamlessly for superior coherency and a very realistic, natural sound. These drivers give great depth and extension to the Kaiser 10’s balanced tuning. The bass is present and very capable but not boosted or forward, the midrange is clear and very smooth with slight warmth, the vocal range has a gentle lift to bring it to the forefront, and the excellent treble is smoothly bright and non-fatiguing. With no sonic weaknesses, the Kaiser 10 does very well with a wide array of music genres, making...

Pros: Adjustible bass with real energy, rich mids and non-fatiguing treble to balance it all. It's a very envolving, lively sound.

Cons: Only works with Shure and Sensaphonics iems;

Sensaphonics 3MAX Custom-fit Stage Monitor

Posted

Pros: Superior comfort and isolation; excellent bass, nicely warm with vocal-centric tuning and very nice treble

Cons: In general, vocal-centric stage monitor tuning can be too much for some at high volumes

Synopsis: The Sensaphonics 3MAX is a top-tier, custom-fit, in-ear monitor with a sound designed by an audiologist and tested by pro musicians.  With a professional clientele in mind, the 3MAX has been superbly engineered for a natural-sounding tuning. Vocal music comes to the fore with a smooth midrange and a non-fatiguing, yet well-extended treble. While its sister, the two-driver 2MAX aims for a more neutral version of this sound, the 3MAX adds an additional bass driver for a judicious warmth and depth. One of the keys to making this sound possible is the excellent silicone shell which gives the 3MAX superior comfort and isolation over the standard acrylic. The end result is a...

An Enjoyable, But Flawed Earphone Not Worth The Price

Posted

Pros: Great Tuning--These Are Fun To Listen To, Good Detail In the Midrange And Treble

Cons: Incoherency Between The Drivers Is Noticeable, Harsh treble with best detailed filter, detail loss with others, High price, Reliability is a concern

Short Review: All observations made with the high pass filters. Naturally I listened with each of the three filters, but the high pass was my preference.   Pros: I really liked the tuning of these. With the K3003, you get an approximation of a neutral sound in terms of a good balance between treble, midrange and bass and the filter system gives you a means of adjusting this balance (at a cost of slightly loss of detail with the non-reference filters). What's great is that the sound is still very fun. I'm not sure I can put my finger on exactly why, but these were great to listen to. I think the combination of the brightness of the treble with the full bass give the fun of a...
