RA10

Following the appearance design and ergonomic rules formulated by NF ACOUS based on the spatial modeling of the human ea. The size of RA10 is small, firm and comfortable to wear, and it has a family-style pick-shaped panel. The sound quality is amazing for a tiny earphone like RA10.

The use of special air permeability tuning damping customized according to actual sound performance can finely adjust the sound balance that cannot be reflected in the test but can be perceived by the human ear, so as to obtain more delicate and calm musical expression. 6 sound tube tuning dampers are randomly provided and can be replaced by yourself.

Relying on NF ACOUS' many years of experience in custom earphone manufacturing, we have formulated a complete set of ergonomic rules, including ear canal angle, cavity angle, and cable exit angle, to fully utilize the anatomy of the human ear for support and minimize wearing pressure induced. Combined with silicone ear tips as small as 9.3mm diameter, most people can enjoy an excellent wearing experience in RA10.

RA10 comes equipped with MCL-6. It is a timbre-focused design which adopts a lightweight, medium-stiffness, high-polymer diaphragm with good elasticity. Combined with carefully designed surface textures, it achieves lower distortion and better musical performance. Strong transient profile is the result of strong neodymium magnets with powerful magnetic field.

RA10 takes the frequency response characteristics of HRTF under the optimized diffusion field as its core engineering goal. Through precise magnetic force, voice coil weight, diaphragm, and glue adjustments, it achieves great performance in terms of dynamics and timbre determined by harmonic characteristics.

The impedance, capacitance and inductance of IEM cables will have a significant impact on the sound. RA10 comes with 5N OFC silver-plated cable. It has the mistake-proofing plug but can still support other NF ACOUS cables.
