Radius HP-NX100 Hi-Res Audio Earphones: MMCX Re-cable Compatible, NeEXTRA Series RAF Driver, Wired, In-Ear Type, HP-NX100R (Red)

[RAF Driver] Featured is the newly developed [RAF Structure (Rear Air Flow system) Driver]. A chamber at the rear of the driver unit precisely controls back pressure, achieving high diaphragm damping. By suppressing diaphragm vibration and reducing unnecessary vibration, the driver delivers improved response to audio signals and excellent transient characteristics with minimal reverberation. [Excellent Acoustic Design] A meticulously engineered acoustic approach delivers a powerful yet wide sound field and high spatial expression. The diaphragm is made of PEEK (Polyether Ether Ketone). Compared to standard PET materials, it offers high rigidity, a good balance of propagation velocity and internal loss, and excellent stability across the entire frequency range. [Excellent High-Frequency and Crisp Low-Frequency] The voice coil uses copper-coated aluminum wire, CCAW. Lighter than standard copper wire, it achieves high diaphragm response and reduces unnecessary vibration. This enables excellent high-frequency extension and crisp low-frequency reproduction. [Deep Mount Earpieces] These earphones feature radius' proprietary [Deep Mount Earpieces]. Unlike conventional earpieces, they feature a wide fitting area, providing an excellent fit that's gentle on the ears, high sound insulation, and rich bass reproduction. [MMCX Re-Cable Compatible] The earphone headset is compatible with MMCX connector re-cabling, so you can change to your preferred cable and enjoy the difference in sound quality. Even if the cable breaks, you can extend the life of your earphones by simply changing the cable.
