Simphonio Dragon 3 - D3

SimPhonio Dragon D3 Dynamic Driver HiFi Audiophile Earbud


On the basis of D2 +, the D3 driver is upgraded to a new 15.8mm 4-layer composite diaphragm, and the driver drive coil is upgraded to a composite material. At the same impedance, the weight is reduced by one third compared to the traditional enameled coil. The dynamic impedance is about 150ohm, but the sensitivity Up to 118dB, which ensures that the mobile phone can also be easily driven. The cable is upgraded to Japan's Furukawa monocrystalline copper wire base-8 core 640 wire thin wire core, which is precisely matched with the left and right light body exhaust.

D3 improves the low frequency on the basis of the sound of D2 +, so that the quality and quantity of the low frequency of the earbud can also compete with the in-ear earphones, and it can be easily retracted. Under the low frequency, the middle frequency is wide and natural, but the high frequency is clear but not bright , smooth but not sharp, making the vocal softer, and the depth of the D3 sound field is significantly improved than that of the D2 +, which gives the wide left and right sound field depth and a stronger sense of stage. This comprehensive new improvement allows D3 to have both the charm of the previous earbud and the quality of the current earbud, achieving a combination of hearing and quality.
