|■A hireso sound source-response model of the "Grand Bass" realizing 重低音 of the force series. Hireso sound source-response headphones "Grand Bass" to adopt a compound vibration board of three levels of structure, and to realize depth and 重低音 of the sharp force in high definition.
■In correspondence with "the hireso sound source" that is a high-resolution music file, it is stereo headphones "Grand Bass" realizing powerful 重低音 of high-quality sound.
■I adopt a dynamic driver of large-diameter φ 12mm and play dynamic sound with a sense of reality by a wide range from a low level to a high level.
■It is richer and, in spite of being a single driver, realizes powerful 重低音 by adopting a compound vibration board of three levels of structure of PEEK+TPU+PEEK.
■If the PEEK film is heat-resistant, an internal loss is high and can hold down a distortion to a minimum. In addition, because rigidity is high, good high level properties are provided and they control unnecessary vibration and regenerate a high minute, delicate sound of the resolution.
■Harmonics distortion rate is low and reproduces depth and 重低域 of the sharp force by the TPU film which had flexibility and strength.
■I go berserk in dynamic and reproduce the low level that の is good for by adopting a high magnetic force neodymium magnet to a magnet.
■I improve a response of the vibration by adopting lightweight CCAW voice coil and realize clear sound quality with a wider range.
■I adopt a stabilizer made of brass to the leg of the driver and realize sharp rich 重低音 by restraining the reaction of the vibration board occurring from driver York.
■I adopt the semi-opening structure that I made a duct for in front and behind a driver unit and realize overwhelming 重低音 and good clear sound of the omission by smoothening the operation of the vibration board by the duct which optimized ventilation resistance more.
■In addition, I realize rich low tone reproduction by adopting a large-diameter sound pipe.
■I adopt ear cap "that the depth direction can regulate mounting location and I raise sealing characteristics and improve low tone expression.
■The electrostatic noise between right and left decreases an electromagnetic noise by becoming the independent separation, and doing the grand code of right and left in 4 lines and realizes soundscape and a firm low tone.
■I use OFC high-purity copper wire realizing the high level reproduction that there is little signal deterioration, and is clear for a cord.
■Gee, the chief balances a feeling of fitting with sound quality improvement by changing the internal and external hardness.
■An ear cap is attached so that a feeling of fitting is available. 4 size that increased smaller XS size is attached to general S M, large size.
■The cord adopts a cord of 1.2m that can be connected relaxedly and can gather up a cord in attached cord goalkeepers.
■It is hard to coil itself round the cord and adopts an elastomer material superior in tolerance.
■Sound insulation characteristics are high and, by earplugs type to fit an ear well," reduce an omission of sound and are available in peace without being influenced by neighboring noises.
■I store headphones well, and the exclusive case of the semi-hardware type that is convenient for carrying around is attached.
