Radius earphone High-MFD structure installed Dynamic driver Canal type HP-NEF31K (black)

High-MFD structure driver Equipped with "High-MFD structure driver". "Sensitivity" and "sound quality" are improved by confining the magnetic flux leaking from the voice coil of the dynamic driver by the repulsive magnetic force of the magnet and increasing the magnetic flux density.;Deep mount earpiece radius Originally developed "deep mount earpiece" is adopted. Unlike the conventional type, it features a wide fitting area, and has an excellent fit that is easy on the ears, has high sound insulation, and achieves rich bass reproduction.;Adjustable port The earpiece mounting position can be adjusted in two stages with the unique "adjustable port", and it can be mounted in the position that suits your taste. By fitting it firmly to your ears, you can improve the sound insulation without missing the bass range and reduce the stress on your ears.;We have adopted a "super multi-layer film" in which hundreds of polyester resin films are laminated on the vibrating film inside the driver unit. It is more rigid than general PET film and realizes more glittering sound quality reproduction.; Type: Dynamic type Driver: 13mm Output sound pressure level: 105dB / 1mW Playback frequency band: 4Hz-25000Hz Maximum input: 200mW Impedance: 18Ω Plug: 3.5mm Gold-plated stereo mini plug Cable length: Approx. 120cm (Y type) Mass: Approximately 14g (including cable)
