The NF ACOUS NH20 is a closed-back dynamic headphone designed to deliver high-fidelity sound. It features a 40mm dynamic driver that delivers a wide frequency response. It is designed to provide optimal comfort thanks to its ear cushions made of cashmere microfiber and PU leather, as well as its adjustable headband, and to ensure long-lasting durability with its nylon carrying case.
The NH20 is equipped with a 40mm NF ACOUS MC2L-400 dynamic driver featuring a beryllium-coated polymer diaphragm that enables an ultra-high magnetic flux density exceeding 1.5 Tesla in the air gap. The zone damping system ensures an extended frequency response from 5Hz to 50 kHz, an ultra-wide dynamic range, and low distortion.
To optimize the low-frequency response (below 100Hz), adjustments were made to improve the perception of bass and harmonies.



To enhance listening comfort, the NH20 features earcups designed to align with the ear thanks to a two-axis tilt mechanism, making it easier to position them parallel to the ear and delivering superior acoustic performance without compromising comfort. The earcup shells, made of cashmere microfiber and hydrolysis-resistant PU leather, are combined with high-density memory foam, providing excellent sound isolation and extended durability.
In addition, to accommodate different user setups, the headset features left and right ports for connecting the cable. Its specialized circuitry supports a standard 4-pole 3.5mm jack, ensuring optimal sound quality regardless of the connection method.
To ensure optimal protection for the helmet, it comes with a stylish and durable nylon storage case featuring a high-strength EVA-lined interior.
