Radius Earphones Dynamic Driver with High-MFD Structure, Canal Type HP-NEF31S (Silver)

High-MFD structure driver Equipped with "High-MFD structure driver". Magnetic flux leaking from the voice coil of the dynamic driver is confined by the repulsive magnetic force of the magnet, and by increasing the magnetic flux density, "sensitivity" and "sound quality" are improved.Deep Mount Earpiece Uses the "deep mount earpiece" developed by . Unlike the conventional model, it features a shape with a wide fitting area, realizing an excellent fit that is gentle on the ears, high sound insulation, and rich bass reproduction.Adjustable Port You can adjust the mounting position of the earpiece in two stages with the unique "Adjustable Port" mechanism, so you can wear it in the position that suits your preference. By fitting it tightly to your ears, you can reduce the stress on your ears by improving sound insulation without missing the low range.A "super multi-layer film" made by laminating hundreds of polyester resin films is used for the diaphragm in the driver unit. It has higher rigidity than general PET film, and achieves more brilliant sound quality reproduction.Format Dynamic type Driver 13mm Output sound pressure level 105dB/1mW Reproduction frequency band 4Hz - 25000Hz Maximum input 200mW Impedance 18Ω Plug 3.5mm gold-plated stereo mini plug Cable length Approx. 120cm (Y type) Weight about 14g (including cable)
