NF ACOUS NM25 Studio-Grade Dynamic Monitoring Earphones
NF ACOUS NM25 is engineered to deliver studio-level sound precision and the highest reference value for musicians and sound creators. Designed for creators who demand accurate feedback, dynamic transient response, and crystal‑clear detail, the NM25 offers faithful reproduction across instruments, vocals, recording, mixing, editing, and live monitoring.
Professional Studio Sound, Anytime
The frequency response is tuned toward a Diffuse Field reference with a subtly enhanced low end, compensating for bone‑conduction bass loss. The result: a balanced, analytical sound signature perfect for accurate monitoring in any environment.
Main Features
MC2L‑100P Dynamic Driver
Equipped with a dual‑magnetic, dual‑chamber electro‑tuned dynamic driver featuring an advanced damping system. This architecture provides precise control of instantaneous dynamics across frequency bands, offering superior clarity and resolution with rich micro‑details.
Noise Trap 2.0 Acoustic Tuning Technology
Traditional in-ear designs show a resonance peak near 5 kHz. The NM25 counteracts this using a precisely engineered Helmholtz resonator (±0.02 mm tolerance), delivering smooth high‑frequency response without distortion — acting like a physical EQ with high Q‑factor precision.
Next‑Gen Monitoring Design
An upgraded internal acoustic structure integrates five air‑pressure control meshes and two custom acoustic sponges for exact chamber pressure balance — ensuring consistent, reference‑grade sound for professional mixing and monitoring.
Premium CNC‑Machined Metal Housing
Crafted from a solid block of aerospace‑grade aluminum using 5‑axis CNC milling, the NM25 blends matte and glossy finishes for a bold yet refined look. Lightweight yet durable, it shines both on stage and on camera.
Ergonomic Fit, Enhanced Comfort
Leveraging NF ACOUS’s extensive custom earphone design experience, the NM25 refines every angle — from nozzle to cable exit — for maximum comfort, secure fit, and long‑term durability during extended studio or stage sessions.
6.35 mm to 3.5 mm Premium Adapter
Many professional audio setups still rely on 6.35 mm outputs. The NM25 includes a precision-crafted aluminum and gold‑plated adapter for secure connection, enhanced conductivity, and premium tactile feel — a thoughtful addition to every studio setup.
0.78 mm | 2‑Pin Detachable Cable
Enjoy flexibility across devices with the 5N oxygen‑free silver‑plated copper cable (1.3 m, 3.5 mm jack). The reinforced 0.78 mm connector with anti‑misalignment slot improves durability for everyday professional use.
Passive Noise Isolation up to 25 dB
Providing up to 25 dB of passive isolation, the NM25 effectively blocks environmental noise, ensuring pure focus on your mix, even in noisy surroundings — perfect for travel, stage monitoring, or recording sessions.
Ballistic Nylon Protective Case
The NM25 comes with a durable ballistic‑grade carrying case featuring EVA inner padding for outstanding hand feel and superior protection during transport.
MS42 High‑Quality Silicone Eartips
Includes four pairs (XS, S, M, L) of NF ACOUS MS42 antibacterial silicone eartips, engineered for secure fit, optimal acoustic sealing, and lasting comfort during long listening or mixing sessions.
