The rare 3DD dynamic earphones make a stunning debut. The 3DD dynamic driver released this time is believed to have the chance to become the new benchmark for dynamic drivers in the whole industry. 
Compared to any form of dynamic earphones in the entire industry, whether single or 2DD dynamic drivers, the CCA 3DD IEM is expected to become a legendary presence.In terms of the combination and crossover of dynamic driver units, the two dynamic driver units of the CCA 3DD IEM are responsible for the Bass and Sub-bass ranges, while the last dynamic driver is responsible for the high-frequency and ultra-high-frequency ranges. In comparison to conventional single dynamic drivers, traditional dynamic drivers or dual dynamic drivers need to compress the low-frequency to highlight the mid-to-high frequencies. The CCA 3DD IEM uses a three-driver crossover design, with each driver unit responsible for one frequency range, ensuring no interference and maintaining the coloration of the three frequencies.In terms of acoustic structure, compared to traditional molded earphones, which are often cumbersome to produce with low consistency in handmade products and difficult to meet complex structural design requirements, the CCA 3DD IEM adopts a 3D printed inner support combined with mold forming design. This design perfectly solves the complex requirements for acoustic structure. The high-precision 25-micron DLP 3D printed inner support ensures higher production consistency for irregular constructions, smaller tolerances, precise transmission, and stability in quality due to reduced use of glue.
