RA15

The warmth and brightness of sound bring completely different emotional experiences,and these experiences cater to different musical styles.These emotional experiences are what music enthusiasts truly value.Starting from the aspect of 'tone'. RA15's two sound tubes achieve high completion in different tonalities through precise subjective tuning.

Our technical team,under the premise of excellent objective parameters, through extensive subjective listening,adjusts the material,structure, damping material,and other aspects of the two sound tubes.Finally,we adopted "brass"and "stainless steel"sound tubes to achieve high completion "warm"and "bright"tones with better musical adaptability.

The RA15 follows NF ACOUS' design and ergonomic principles based on the shape of the human ear. The new appearance design,family-style pick modeling panel, and matte surface treatment create an acoustic cavity that highlights quality.The metal cavity created by alloy casting, excels in both aesthetics and acoustics.

Optimized for music appreciation, featuring electronic tuning dynamic driver with high dynamics,large output,and a frequency range of 10-40kHz. Grand soundstage and passionate tone.

Wearing comfort is an important factor in whether the earphones can be used for a long time. Relying on many years of experience in manufacturing customized IEMs,NF ACOUS have developed a complete set of ergonomic rules, including the angle of the ear canal, the angle of the cavity and the angle of the wire,etc,to make full use of the structural shape of the human ear to support and reduce the pressure of wearing.

The usage scenarios of earphones for computers,mobile phones,and professional equipment are different.The replaceable cable design brings more possibilities for earphone usage scenarios.Equipped with a 3.5mm plug and a 1.3m 5N oxygen-free copper silver-plated cable,it is more suit- able for use with music players and other devices with a 3.5mm earphone connector
