Customer Review Summary
Introduction to the Neumann NDH 20
The Neumann NDH 20 represents the brand’s first foray into the headphones market, launched in February 2019. Priced at £469, these closed-back, over-ear headphones are designed for professional studio use, particularly music production, sound design, and mixing. They aim to deliver uncompromising linearity and clarity while providing robust isolation and a comfortable wear experience for extended sessions.
Build Quality and Design
The NDH 20 showcases a solid construction largely crafted from aluminium, giving the headphones a durable yet premium feel. The earcup covers are lightweight aluminium, contributing to the overall weight of 388 grams without cable. The headband is adjustable with a flexible steel framework, and memory foam ear pads provide firm cushioning around the ears.
In practical application, the build quality is praised for solidity and aesthetic appeal, though the headphones are somewhat heavy and bulky on the head. Some users, especially those wearing glasses, have required a settling-in period to find a comfortable fit due to the firm clamping force. The cable is fixed on the right earcup and comes with a choice of straight or coiled wire, including a 6.3 mm adapter for wider compatibility.
One notable downside is cable noise transmission. The cable is relatively stiff with a coarse texture, causing friction noises when it brushes against clothing or is handled during quiet passages. This makes it necessary to stay very still during critical listening to avoid interference.
Sound Signature and Performance
The NDH 20 is characterised by an impressively neutral and revealing sound profile, suitable for detailed studio monitoring. Its frequency response stretches from 5 Hz to 30 kHz, nearing a full-range reproduction with dynamic 38 mm drivers powered by neodymium magnets. The impedance is set at 150 Ohms, requiring sufficient amplification to reach optimal performance.
- Clarity and Precision: The headphones offer crystalline midrange detail and natural vocal presence, making them ideal for tracking vocals and acoustic instruments.
- Neutrality: Unlike many consumer models, the NDH 20 avoids artificial enhancement in bass or treble, instead presenting a flat and honest representation of source material.
- Bass Response: Initially perceived as slightly emphasised, the bass settles quickly after a brief break-in period to blend seamlessly with the rest of the spectrum without overshadowing mids or highs.
- High Frequencies: The treble is smooth and non-fatiguing, with very low total harmonic distortion below 0.10% at 100 dB SPL, ensuring crispness without harshness.
- Soundstage and Imaging: Being closed-back, the headphones offer less spaciousness compared to open-back competitors. The soundstage is relatively intimate, which some users find excellent for mixing, while others feel it restricts the perception of stereo effects and depth.
Comfort and Practicality for Studio Use
Users generally find the NDH 20 comfortable for long durations once properly fitted. The memory foam ear pads supress ambient noise effectively, although isolation is not quite as robust as some rivals like the Beyerdynamic DT770. The ear cushions can wear prematurely, requiring replacement to maintain comfort and fit.
The fixed right-side cable can annoy left-handed users or those accustomed to left-cabled headphones. Additionally, the coiled cable option is considered heavy and cumbersome by some. The inclusion of both a straight and spiral cable, alongside a fabric travel pouch, enhances versatility, although the carrying case is basic.
Comparisons and Applications
Against other studio headphones in the mid to high price bracket such as Beyerdynamic DT1990 Pro, Sennheiser HD660S, and Focal Clear, the NDH 20 stands out for its neutrality and midrange accuracy. Those headphones offer more open soundstages or brighter tonal characters, but the NDH 20 excels in its truthful, non-embellished sound, which is priceless for critical mixing and recording.
The NDH 20 especially shines in classical, orchestral, and vocal recording contexts, where the faithful reproduction of instrumental timbres and fine details is critical. Electronic and rock genres are well represented but may reveal the closed-back limitations in spatial imaging.
Amplification and Compatibility
With 150 Ohms impedance and 114 dB sensitivity, the NDH 20 benefits from a dedicated headphone amplifier or audio interface with strong headphone out. Some struggles have been noted using laptops or mobile devices without amplification, leading to less dynamic sound and reduced clarity.
Summary and Verdict
Neumann’s NDH 20 is a professional closed-back headphone that brings exceptional clarity, tonal accuracy and solid construction to the studio environment. Its neutral tuning makes it ideal for mixing and monitoring where uncoloured audio is crucial. Limitations include somewhat heavy weight, cable microphonics, and a less expansive soundstage typical of closed designs.
While not perfect, especially regarding cabling and fit nuances, the NDH 20 is an excellent choice for users prioritising precision and fidelity, who are prepared to provide suitable amplification and careful handling. It competes strongly against established models at a comparable price point, expanding Neumann’s distinguished reputation into the headphone market.
