On paper, these Neumann headphones promise a relatively high impedance. In practice, a high sensitivity ensures this is fit for task even with lower spec headphone amplifiers such as the tech found within your favourite smartphone. Fitment on the fixture was VERY difficult. It would not fully surround the artificial ear, and I could not get it to fully seal no matter what I did. Slight movements and changes would vary the levels but in practice, I noticed frequency response did not substantially change. Still, be on notice that my confidence in measurements are not super high (although EQ settings verified that they were good enough for that purpose). The NDH 30 owes its superior linearity, among other things, to frequency-selective absorbers that eliminate the overemphasis in the high frequencies that leads to incorrect mixing decisions in many other headphones. For example, the NDH 30 will accurately reveal whether a voice sounds muffled or needs a de-esser. I used the Merging Anubis audio interface for sound quality testing because it’s the closest available thing to the just-released Neumann MT48. The Anubis was connected to my PC via the Ravenna AES67 network connection. I used my usual suite of music from many different genres and sources, both lossless and lossy.
Having headphones tonally sound like calibrated speakers in a decent room has been the gold standard for developing target curves. The NDH 20 implements newly designed 38mm driver with high-gauss neodymium magnets for high sensitivity and low distortion. According to Neumann, these drivers eliminate the need for a dedicated headphone amplifier as they can be just as easily powered by mobile devices like smartphones and laptop computers.Die Stereobühne ist auf Grund der geschlossenen Bauweise nicht so weittragend wie bei den DT990 oder NDh 30, aber dafür dringt absolut kein Geräusch nach aussen oder nach innen. Für mich deutlich wichtiger, das Panorama mische im Feintuning über die Monitore. The treble and upper-treble on the NDH 30 are detailed yet slightly uneven. There’s no severe peaking that imbues the sound signature with faux detail, just enough to make overtones sound strange if they hit the right regions. Not terrible, but also not too remarkable. Where to Buy Versteht mich nicht falsch, auch ohne die Monitore machen die Kopfhörer einen hervorragenden Job. Sie sitzen bequem, trotz des Gewichts, sie sind absolut tadellos verarbeitet und der Sound ist so präzise, wie ich es noch nie vorher gehört habe. Jede kleine Veränderung am Mix stellen diese Kopfhörer direkt dar. I suspect that once again, this is totally related to the gear being used, with the "treble enhanced" reviewer using something that is SS and bass lean. I would also like to give a special thanks to Jeff Jent at sweet water for his help though out the many years.
Mids...........Neutral, yet, because the tone of the overall sound of the headphone is so flat, there is a perception of dryness to the presentation, as would be expected. There is one credible video review online and the reviewer cites their sound as dead flat and amazing. I had to play a lot with these dials as the sound wound up being too bright after my initial correction. I was mostly happy with it but not quite there. It is possible some would prefer the heavier bass response.
Neumann NDH 20 Closed Back Headphones
Neumann states that these headphones sound like their monitor speakers calibrated to flat in a treated control room. The NDH 30 can be folded flat for transportation, but there is no hard case. Neumann don’t publish frequency response plots for either model, but quote upper and lower limits of 34kHz and 12Hz for the NDH 30s. Without any tolerances, these figures are of limited value, and I doubt anyone will notice the differences compared with the NDH 20s’ alleged 7Hz‑30kHz bandwidth. What may be more noticeable is that the NDH 30s improve significantly on the NDH 20s’ already impressive distortion figures, taking THD from below 0.1 percent for a 1kHz input at 100dB SPL, to less than 0.03 percent. Whatever they’ve done, it’s worked, because these headphones sound really, really good. Drawing A Line The Neumann's are Interesting headphones that will appeal more to the professional recording musician, first and foremost, and also to the discriminating Audiophile who can appreciate the idea that each (Model) of (good sounding) headphones is a unique experience that is not like any other. The NDH 20 uses newly designed drivers (38 mm/1.5”) with high-gauss neodymium magnets to ensure high sensitivity and minimized distortion, thus allowing the user to listen to the pure audio signal without unwanted coloration. The mechanical construction, too, meets the highest standards. The adjustable headband is made of flexible steel while the ear cup covers are machined from lightweight aluminum. For easy transportation the headphone is foldable and can be placed into the supplied soft cloth bag. Two detachable cables (one straight, one coiled) and a 6.3 mm (1/4”) adapter are also included. Applications
There is less roll-off than on the HD6XX series headphones, and deep notes carry almost no distortion or noise. Just like with the NDH 20, Neumann engineers are doing wonders with the Sennheiser 40mm (or 38mm?) driver. However, if there's one other part that rivals the microphone in significance, it's the monitoring system. No self‑respecting studio can afford to skimp in this area either, and in 2005, Neumann's parent company Sennheiser acquired German loudspeaker manufacturers Klein+Hummel. Four years later, the studio monitor arm of K+H was folded into the Neumann stable, and since then, there have been numerous loudspeaker releases under the Neumann brand. These have built on K+H's already strong reputation to develop a very highly regarded product portfolio. In my opinion, this headphone is exactly what its designed to be.........a studio monitor on your head, first and foremost, and an Audiophile tool for those who prefer flat and clear, vs sweet, or rich, or overly extended. Delivery prices are subject to change and delivery is not guaranteed due to circumstances beyond our reasonable control.These are Keepers and every one I sent a photo to is Jealous! they look like a piece of audio artwork, and well sound great. Neumann is known for being an objective audio lover’s darling in the audio monitoring scene. All of their speakers exhibit state-of-the-art measured performance, yet they haven’t quite reached the mythical status of Augspurger, ATC, or PMC, mainstays of superstar studios around the globe. Technical Specifications The removable headphone cable is light but has this spring action to it that was annoying. I literally had to put something on top of it on my desk to keep it from interfering with my mouse.
It’s not the “feels like I’m wearing nothing” act the Sennheiser HD800 pull off, but I could wear the NDH 30 for a full day. The pads are circular, huge, and cushy. These headphones use clamping force to stay on your head, but it’s never annoying. There are no pressure hotspots and no HD650 cheekbone death grip. The pads on the NDH 30 are plush and let me listen to music for hours without discomfort. InternalsPlaying the "Aja" album by Steely Dan is a "go to" to discern if any cans are able to dig out the bass response, as this album does not have an overly projected bass, its quite neutral....nd many headphones are lost trying to find it. Let me tell you exactly the sound of these headphones, as when i first started listening hours ago, i recognized such a similarity with another set of headphones. Warum nun sind Sie eine tolle Ergänzung zum KH120 (oder die KH120 eine tolle Ergänzung zu diesen Kopfhörern) ? While most of the frequency spectrum on the NDH 30 is faithfully reproduced, they have a curious upper-mid scoop starting at 1.5kHz right up to 3.5kHz. Audibly, it makes the overall tonality calmer and inoffensive but also robs voices, strings, and synths of their bite. Thus the listening experience is very easy on the ears but also quite uninvolving. Technicalities It’s not an understatement to call Neumann a legendary pro audio company. Their microphones have been used by all kinds of celebrities – starting from a certain controversial Austria-born politician in the 1930s all the way up to now with Billie Eilish and others looking to make their mark upon the world with sound.
