The NF ACOUS NM25 IEM is a professional in-ear monitor built for musicians, engineers, and discerning listeners who want reference-level accuracy without sacrificing musical detail. Pairing an MC2L-100A dynamic driver with patented CLUTTER TRAP 2.0 acoustic technology inside a machined aviation-grade aluminium shell, it keeps resonance tightly controlled across live monitoring, studio production, and critical listening.
MC2L-100A Driver and CLUTTER TRAP 2.0 Acoustic Technology
At the heart of the NM25 is the MC2L-100A dynamic driver working alongside NF ACOUS's patented CLUTTER TRAP 2.0 system to tame unwanted internal resonance and smooth out frequency peaks. The result is deep, controlled low end, natural midrange definition, and clear, extended highs across a 9 Hz to 40 kHz frequency response.
Rated at 32 ohms with 108 dB/mW sensitivity, a 125 dB maximum SPL, and distortion under 1%, the NM25 maintains composure and fine detail even when driven hard by stage monitor packs or studio headphone amplifiers.
Machined Aviation-Grade Aluminium Shell and 25 dB Isolation
Each earpiece is precision-machined from a single piece of aviation-grade aluminium, combining a solid, road-ready structure with a lightweight feel that stays comfortable through long sets or mixing sessions. A snug acoustic seal provides 25 dB of passive noise insulation to block out stage spill and room noise, letting you monitor clearly at safer volume levels.
Detachable Silver-Coated OFC Cable and Included Accessories
The NM25 uses a 0.78 mm dual-pin connection paired with a detachable 5N silver-coated OFC cable terminated in a 3.5 mm jack. In the box, you get ear tips in MS, S, M, and L sizes for a tailored ear-canal seal, a 3.5 mm to 6.35 mm adapter for consoles and interfaces, and a protective storage box.
