Kinera Imperial, electrostatic / BA / DD hybrid 5-driver earphone "ImperialURD"

"Imperial URD"

Sound Earth will release a hybrid earphone "ImperialURD" equipped with an EST (electrostatic) driver / BA driver / dynamic driver from the company's brand Kinera Imperial on March 8 (Tue). The price is open, but it is expected to sell at around 79,990 yen including tax. A model whose name is derived from the "Well of Urd", which is located at the base of the world tree Yggdrasil, which appears in Norse mythology. The driver configuration consists of two Sonion's new-generation composite double electrostatic unit (EST driver) "EST65DB01", two 8mm diameter titanium crystal diaphragm coaxial double dynamic drivers, and one Kinera custom "K26005/9" BA driver. , Equipped with a total of 5 drivers. Regarding the direction of tuning, the 3 bands are evenly distributed for each of the high frequency EST driver, low frequency dynamic driver, and mid frequency custom BA driver. It is appealing that it clarifies the vocal area while snuggling up to the original sound and gives a sense of wrapping the whole sound. The housing is molded by 3D printing. A dent in the center of the faceplate and a complex design with a total of 6 layers that gradually swell toward the edge is expressed. Furthermore, by mixing special pigments with different densities, casting the structure of each layer separately, and solidifying it, the water surface of the "well of Urd", which is also the naming motif, was reproduced. The attached cable (approximately 1.2m), which uses a detachable plug that can be easily replaced with 2.5mm balanced, 3.5mm unbalanced, and 4.4mm balanced plugs, uses a mixture of gold-plated OCC and silver-plated OCC on the outside to improve sound quality. Pursuit. By adopting a special shield structure, it is said to have stable impedance and high sound signal transmission efficiency. A 2-pin plug is used for the connection with the earphone. In addition, 3 types of silicone earpieces and 1 type of foam type are included. You can enjoy different sounds. The playback frequency band is 5Hz - 50kHz, the impedance is 20Ω, and the sensitivity is 107±2dB.
