The NF ACOUS NH20 is the brand’s first foray into full-size over-ear headphones, expanding from their long history of in-ear monitors into a closed-back studio monitor design. Positioned around ~$199 USD, the NH20 aims to offer both studio-ready neutrality and enjoyable everyday musicality, bridging the gap between professional monitoring and consumer listening use. This makes it appealing to creators, audio enthusiasts, and listeners who prefer accurate yet engaging sound.
It is interesting product on a market. It tries to bring closer the idea of musical headphones, that can be enjoyed by Audiophiles, but also to be accurate enough to be used for mixing and studio work. And it is headphones that are closer than ever to that ideal. I think this can be used for listening music when you are walking, sitting, running... and yet for work in Abelton etc.
It is an incredible thing as there is not many headphones that do that, or starve for something like that. Making them an interesting proposition on market and something you should definitely check out if you can.
Specifications & Features
Here’s what the NH20 brings to the table:
40 mm dynamic driver with dual magnetic circuit and beryllium-plated polymer diaphragm for high resolution and wide dynamic range.
Frequency Response that is Wide 5–50 kHz range for detailed highs and extended bass.
Impedance of50 Ω, making them easy to drive with both portable devices and desktop DAC/amps. And sensitivity around 110 dB/mW — responsive and imprinting clarity at moderate power levels.
It is a Closed-back earcups designed to enhance low-frequency response and isolate sound in noisier environments. Two detachable 6N OFC cables (1.2 m and 3 m) plus a 3.5 mm-to-6.35 mm adapter; clever bidirectional connection means you can plug on either side without flipping channels.
These specs show the NH20 isn’t just another consumer headphone — NF ACOUS built them with studio mindset features like neutral tuning, flexible cabling, and extended bandwidth.
Build Quality & Comfort
In terms of build and ergonomics:
The NH20 feels robust and well-engineered, using a combination of strong plastics, stainless pivot joints, and a steel-reinforced headband — all built for durability.
Ear cups are padded with cashmere microfiber and resistant PU leather, offering a comfortable seal and good passive isolation.
At about 270 g without cables, these are light enough for extended studio sessions or listening periods without undue fatigue.
Detachable cables and a hard-shell carry case add to practicality, although you may need to disconnect cables to store them tidily. Overall, the design feels purposeful rather than flashy — built for use more than just shelf appeal.
Sound Quality
Bass
The NH20’s bass response is controlled yet satisfying. It offers firm mid-bass punch without overwhelming the rest of the spectrum, and its sub-bass extension adds depth without bleeding into the mids. This fits a monitoring-oriented signature while still remaining engaging for everyday listening.
Midrange
Mids are natural, clear, and forward enough to allow vocals and instruments to shine without sounding artificially scooped or recessed. Some recordings show a slight dip around lower mids depending on setup, but overall the NH20 maintains intelligibility and warmth.
Treble
Highs are crisp and articulate, thanks to the beryllium-plated driver design. There’s good detail retrieval and clarity — a benefit for critical listening and identifying subtle mix cues — but the treble might lean a bit bright for listeners sensitive to sharp highs.
Soundstage & Imaging
For closed-back headphones, the NH20’s soundstage isn’t cramped; it feels surprisingly spacious and layered, with good imaging for positioning instruments and elements in a mix. This makes them functional for both music and gaming.
Pairing & Usability
Because of its mild impedance and high sensitivity, the NH20 pairs easily with a variety of sources — from smartphones and portable DACs to desktop rigs and interfaces. They don't demand a powerful amp yet respond well to better amplification or EQ shaping. The included 1.2 m cable suits portable use, while the 3 m cable and adapter are perfect for studio desks or home setups.
Competition
At ~$199, the NH20 competes with:
vs. Audio Technica ATH-M50x
Audio-Technica ATH-M50x – A classic reference headphone with stronger bass punch but less openness. The NH20 feels more detailed and balanced in comparison.
vs. Adam Audio H200
Adam Audio H200 – Another closed-back that trades off slightly more emphasis on warmth and bass for a different listening flavor. Compared to it, the NH20 leans a touch more neutral and analytical.
In this segment, many traditional monitors either emphasize one trait (bass, warmth) or lack technical neutrality. The NH20’s strength is its combination of monitoring accuracy and everyday usability, which many rivals don’t balance as well.
Conclusion
The NF ACOUS NH20 is an impressive first full-size headphone release from the brand, successfully translating their sound signature from in-ears to over-ears. They manage a neutral-tuned yet engaging sound, good build quality, and practical features like detachable bidirectional cables and a solid carrying case. They are especially suited for listeners who want studio-oriented accuracy without sacrificing musical enjoyment.
If you’re after pure fun-oriented bass or rich coloration, there are warmer options out there. But if you want a versatile, detailed, and comfortable headphone that works for both mixing and casual listening, the NH20 stands out at its price and is worth serious consideration.
