LINSOUL CCA Trio 3DD Black HiFi Earphones Professional Filters with Switch for Customizable Adjustment Earbuds High-End Built-in 4-Level (with Mic)

---------------------------------------------------------------------- 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ---------------------------------------------------------------------- Innovative ultra-thin 4-layer voice coil, Trio's dynamic driver uses an internal 4-layer voice coil with a diameter of approximately 0.05mm. A sufficiently thick voice coil improves the speaker's power handling compared to ordinary dynamic drivers, resulting in more pleasant bass performance. Development of CCA's strong magnetic circuit structure The magnetic circuit system directly affects the final output frequency response, harmonic distortion, etc. of the speaker. CCA's uniquely developed magnetic circuit structure has been repeatedly adjusted to achieve a more rational structure. This significantly improves the magnetic properties of the speaker and reduces nonlinear distortion. It delivers better and better tone quality than any other dynamic IEM from any other brand. In terms of sound, the CCA Trio can be described as a "versatile Harman." Compared to the traditionally conservative "Harman" sound, the CCA Trio inherits the natural feel of the traditional Harman sound, with deep sub-bass and well-controlled bass impact to deliver full, natural vocals. Structural optimization improves high frequency details and vocal separation. We also add 4 adjustable modes to provide you with a unique and enjoyable hearing experience. 3DD's innovative dynamic driver structure design. Each driver works independently. In the dynamic driver unit combination and crossover, the previous DQ6S used two dynamic drivers for high frequencies. In contrast, the CCA Trio employs two dynamic driver units, each responsible for the bass and sub-bass, and the last one for the mids and treble. Unlike a traditional single dynamic driver or two dynamic drivers, which must compress the bass and accentuate the mids and treble, CCA Trio uses a three-driver crossover design. Each frequency band is processed by three independent units to ensure interference-free performance and maintain the integrity of the three frequency bands. Precise electronic three-way crossover technology for stunning audio quality Trio uses a crossover switch design to precisely calculate how each unit's frequency affects the sound quality of different frequency bands. This ensures seamless integration between bass, midrange, treble, and ultra-treble, resulting in an overall tri-frequency balance, delicate auditory sensation, and rich detail. Precise division of three dynamic drivers Trio uses a unique design and is equipped with three 8mm high-performance dynamic drivers. Each driver focuses on a specific frequency range to accurately represent every detail of your music. Attention to detail reveals extraordinary quality. In the process of pursuing superior quality, we spare no effort. Attention to detail reveals true excellence.
