“Preface This is a short review intended for concise information presentation. The data presented in this review was provided by a good friend and a disinterested third party to whom I owe many thanks! All data is uncompensated (except for 1/12th octave smoothing), and measured with a fully IEC-60711 (IEC60318-4) compliant ear simulator. Why Review the AM70? Over the past...” --tomscy2000
“Foreword: I'm a production manager, but focus mostly on sound engineering and installations. I install and tune a lot of P.A equipment, and also mix live acts. My work environments consist mainly of: - live venues, - concert halls, - bars - nightclubs. - festivals - events I've taken a huge liking to headphones - IEM's in particular. I like the idea of having my own personal PA...” --White Lotus
“Astrotec has been mostly into budget IEMs until recently, when they introduced their AX60, AX7 and now their AX30/35. The version I have here today is the AX35. I’m not sure of the prices yet, but from what I hear, the AX30 will be around $65 while the AX35 will be $80 (USD). The AX30 is supposed to be the bassier model of the two while the AX35 was tuned to be more neutral. Me generally...” --lin0003
“ (copied and pasted from the thread) Intro Noble Audio is the new brain child of John Molton, who is known around these parts as the Wizard. Formerly of Heir Audio, his CIEM designs are usually his calling card. However, his initial universal-fit 4.Ai and 3.Ai, and 5 designs saw a...” --eke2k6
The Noble 4 is a neutral sounding product that should appeal to those who desire a flatter frequency response. An update from the Wizard’s four-driver design, the Noble 4 lacks the controversial dip in the high frequency region. The smooth, clean, sound makes for an ideal pairing with vocal, acoustic, and classical music.
The Noble 5 was inspired largely by the demand for a universal version of the Noble 8C (eight-driver acrylic CIEM). With deep, thick layered, bass and highs that never fatigue the ear, the Noble 5 strikes a balance between fun and articulate.
The Noble 3 is a complete overhaul of Wizard’s original three-driver design, a process that involved lots of consultation with Knowles (leading balanced-armature driver manufacturer). With a ‘V’ shaped frequency response, the Noble 3 is characterized by a controlled, impactful, low end and far-reaching highs.
“ 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...” --Kunlun
“ 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...” --Kunlun
“I'm listening to these through a Schiit Modi DAC and Schiit Asgard 2 amplifier (totally overkill for these, but I was listening with DT990's before). I listen mostly to CDs which I own and rip securely, in addition to Spotify's subscription-quality streaming. I'm not very experienced with reviewing headphones, but I will say this: These are my first CIEMs, and with this I purchase...” --Baldoak
