HiFiGo CVJ Kumo Flagship 8 BA Balanced Armature IEM Earphones with 4 Tone Tuning Switch and 3 Interchangeable Plugs In-Ear Monitors, In-Ear (Kumo)

------------------------------------------------------------------------------------------------------------------ 【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. ------------------------------------------------------------------------------------------------------------------ Each balanced armature serves a purpose: never blindly stack units. The compact 29689 mid-frequency balanced armature and 22955 low-frequency balanced armature drivers deliver superior audio density and incredibly dynamic low frequencies. The addition of the 31736 composite balanced armature driver creates a longitudinal sound field, complementing the high and very high frequency ranges. Switch between over 12 sound styles with 4-tone tuning: You're both the listener and the sound engineer. Freely switch the 10 rotary switches to adjust bass, mid-high, and ultra-high frequencies, and access more than a dozen great system cards to fully explore the fun of tuning. No longer do you need to passively apply a uniform sound, you can customize and fine-tune high-fidelity audio to individual tones. [Hand-assembled sound guide tube, smooth connection, pure sound emission] The sound guide tube sound emission system is hand-assembled by professional acoustic engineers. Knowles damper softens the balanced armature sound, effectively reduces burrs and filters excess noise. Ensure a smooth connection, easily drive 16 sound units, and refine the pure sound from your source. PCB Board Electronic Tuning Proud Frequency Response Curve: Based on an oversized configuration of multiple pure balanced armature units, the professional grade PCB board crossover circuit design maximizes the performance benefits of each unit. A unique reverse output process adds extra charm to your sound. KUMO's frequency response curve, listening texture, and performance parameters are sufficient to outperform similar products in the same price range. CNC aviation grade aluminum alloy, matching excellent sound quality and elegant appearance: using CNC machining technology. Aircraft grade aluminum is hollow throughout. Adopting a lightweight and robust metal cavity, it effectively reduces resonance and maintains stable high sound quality. Simple geometric contours highlight the novelty and give elegance in all aspects.
